-# HackMD CE became CodiMD
+We welcome contributions! There's a lot to do: If you would like to report bugs,
+the [issue tracker][github-issue-tracker] is the right place. If you can help
+translating, find us on [POEditor][poeditor-url]. To get started developing,
+take a look at the [docs/dev](docs/dev) directory. In any case: come talk to us,
+we'll be delighted to help you with the first steps.
 
-CodiMD was recently renamed from its former name was HackMD. CodiMD is the free software version of HackMD. It was the original Version of HackMD. The HackMD team initiated CodiMD and provided a solid code base. Due to the need of paying bills, A fork was created and called HackMD EE, which is a SaaS (Software as a Service) product available at [hackmd.io](https://hackmd.io).
+To stay up to date with our work or get support it's recommended to join our
+[Matrix channel][matrix.org-url], stop by our [community forums][codimd-community]
+or subscribe to the [release feed][github-release-feed]. We also engage in
+regular [community calls][codimd-community-calls] ([RSS](https://community.codimd.org/t/codimd-community-call/19.rss)) which you are very welcome to join.
 
-We decided to change the name to break the confusion between HackMD and CodiMD, formally known as HackMD CE, as it never was an open core project.
 
-Just to more confusion: We are still friends with HackMD :heart:
+## Installation / Upgrading
 
-*For the whole renaming story, see the [related issue](https://github.com/hackmdio/hackmd/issues/720)*
+You can run CodiMD in a number of ways, and we created setup instructions for
+all of these:
 
-# Browsers Requirement
+* [Docker](docs/setup/docker.md)
+* [Kubernetes](docs/setup/kubernetes.md)
+* [Cloudron](docs/setup/cloudron.md)
+* [LinuxServer.io (multi-arch docker)](docs/setup/docker-linuxserver.md)
+* [Heroku](docs/setup/heroku.md)
+* [Manual setup](docs/setup/manual-setup.md)
+
+If you do not wish to run your own setup, you can find a commercial offering at
+https://hackmd.io. This is not the same codebase as this one, but it is a very
+similar project.
+
+
+## Configuration
+
+Theres two main ways to configure your CodiMD instance:
+[Config file](docs/configuration-config-file.md) or
+[environment variables](docs/configuration-env-vars.md). You can choose what
+works best for you.
+
+CodiMD can integrate with
+
+* facebook, twitter, github, gitlab, mattermost, dropbox, google, ldap, saml and [oauth2](docs/guides/auth/oauth.md) **for login**
+* imgur, s3, minio, azure **for image/attachment storage** (files can also be local!)
+* dropbox **for export and import**
+
+More info about that can be found in the configuration docs above.
+
+
+## Browser support
+
+To use CodiMD, your browser should match or exceed these versions:
 
 - ![Chrome](http://browserbadge.com/chrome/47/18px) Chrome >= 47, Chrome for Android >= 47
 - ![Safari](http://browserbadge.com/safari/9/18px) Safari >= 9, iOS Safari >= 8.4

-# Installation
 
-## Getting started (Native install)
-
-### Prerequisite
-
-- Node.js 6.x or up (test up to 7.5.0)
-- Database (PostgreSQL, MySQL, MariaDB, SQLite, MSSQL) use charset `utf8`
-- npm (and its dependencies, especially [uWebSockets](https://github.com/uWebSockets/uWebSockets#nodejs-developers), [node-gyp](https://github.com/nodejs/node-gyp#installation))
-- For **building** CodiMD we recommend to use a machine with at least **2GB** RAM
-
-### Instructions
-
-1. Download a release and unzip or clone into a directory
-2. Enter the directory and type `bin/setup`, which will install npm dependencies and create configs. The setup script is written in Bash, you would need bash as a prerequisite.
-3. Setup the configs, see more below
-4. Setup environment variables which will overwrite the configs
-5. Build front-end bundle by `npm run build` (use `npm run dev` if you are in development)
-6. Modify the file named `.sequelizerc`, change the value of the variable `url` with your db connection string
-   For example: `postgres://username:password@localhost:5432/codimd`
-7. Run `node_modules/.bin/sequelize db:migrate`, this step will migrate your db to the latest schema
-8. Run the server as you like (node, forever, pm2)
-
-## Heroku Deployment
-
-You can quickly setup a sample Heroku CodiMD application by clicking the button below.
-
-[![Deploy on Heroku](https://www.herokucdn.com/deploy/button.svg)](https://heroku.com/deploy?template=https://github.com/hackmdio/codimd/tree/master)
-
-If you deploy it without the button, keep in mind to use the right buildpacks. For details check `app.json`.
-
-## Kubernetes
-
-To install use `helm install stable/hackmd`.
-
-For all further details, please check out the offical CodiMD  [K8s helm chart](https://github.com/kubernetes/charts/tree/master/stable/hackmd).

-The easiest way to setup CodiMD using docker are using the following three commands:
-
-```console
-git clone https://github.com/hackmdio/docker-hackmd.git
-cd docker-codimd
-docker-compose up
-```
-Read more about it in the [docker repository…](https://github.com/hackmdio/docker-hackmd)
-
-# Upgrade
-
-## Native setup
-
-If you are upgrading CodiMD from an older version, follow these steps:
-
-1. Fully stop your old server first (important)
-2. `git pull` or do whatever that updates the files
-3. `npm install` to update dependencies
-4. Build front-end bundle by `npm run build` (use `npm run dev` if you are in development)
-5. Modify the file named `.sequelizerc`, change the value of the variable `url` with your db connection string
-   For example: `postgres://username:password@localhost:5432/codimd`
-6. Run `node_modules/.bin/sequelize db:migrate`, this step will migrate your db to the latest schema
-7. Start your whole new server!
-
-
-* **migrate-to-1.1.0**
-
-We deprecated the older lower case config style and moved on to camel case style. Please have a look at the current `config.json.example` and check the warnings on startup.
-
-*Notice: This is not a breaking change right now but in the future*
-
-* [**migration-to-0.5.0**](https://github.com/hackmdio/migration-to-0.5.0)
-
-We don't use LZString to compress socket.io data and DB data after version 0.5.0.
-Please run the migration tool if you're upgrading from the old version.
-
-* [**migration-to-0.4.0**](https://github.com/hackmdio/migration-to-0.4.0)
-
-We've dropped MongoDB after version 0.4.0.
-So here is the migration tool for you to transfer the old DB data to the new DB.
-This tool is also used for official service.
-
-# Configuration
-
-There are some config settings you need to change in the files below.
-
-```
-./config.json      ----application settings

-## Operational Transformation
-
-From 0.3.2, we started supporting operational transformation.
-It makes concurrent editing safe and will not break up other users' operations.
-Additionally, now can show other clients' selections.
-See more at [http://operational-transformation.github.io/](http://operational-transformation.github.io/)

+Configuration Using Config file
+===
+
+You can choose to configure CodiMD with either a config file or with
+[environment variables](configuration-env-vars.md). The config file is processed
+in [`lib/config/index.js`](../lib/config/index.js) - so this is the first
+place to look if anything is missing not obvious from this document. The
+default values are defined in [`lib/config/default.js`](../lib/config/default.js),
+in case you wonder if you even need to override it.
+
+Environment variables take precedence over configurations from the config files.
+To get started, it is a good idea to take the `config.json.example` and copy it
+to `config.json` before filling in your own details.
+
+
+## Node.JS
+
+| variables | example values | description |
+| --------- | ------ | ----------- |
+| `debug` | `true` or `false` | set debug mode, show more logs |
+
+
+## CodiMD basics
+
+| variables | example values | description |
+| --------- | ------ | ----------- |
+| `allowPDFExport` | `true` | Whether or not PDF export is offered. |
+| `db` | `{ "dialect": "sqlite", "storage": "./db.codimd.sqlite" }` | set the db configs, [see more here](http://sequelize.readthedocs.org/en/latest/api/sequelize/) |
+| `dbURL` | `mysql://localhost:3306/database` | set the db URL; if set, then db config (below) won't be applied |
+| `forbiddenNoteIDs` | `['robots.txt']` | disallow creation of notes, even if `allowFreeUrl` is `true` |
+| `loglevel` | `info` | Defines what kind of logs are provided to stdout. |
+| `imageUploadType` | `imgur`, `s3`, `minio`, `azure`, `lutim` or `filesystem`(default) | Where to upload images. For S3, see our Image Upload Guides for [S3](guides/s3-image-upload.md) or [Minio](guides/minio-image-upload.md)|
+| `sourceURL` | `https://github.com/codimd/server/tree/<current commit>` | Provides the link to the source code of CodiMD on the entry page (Please, make sure you change this when you run a modified version) |
+| `staticCacheTime` | `1 * 24 * 60 * 60 * 1000` | static file cache time |
+| `tooBusyLag` | `70` | CPU time for one eventloop tick until node throttles connections. (milliseconds) |
+| `heartbeatInterval` | `5000` | socket.io heartbeat interval |
+| `heartbeatTimeout` | `10000` | socket.io heartbeat timeout |
+| `documentMaxLength` | `100000` | note max length |
+
+
+## CodiMD paths stuff
+
+these are rarely used for various reasons.
+
+| variables | example values | description |
+| --------- | ------ | ----------- |
+| `defaultNotePath` | `./public/default.md` | default note file path<sup>1</sup>, empty notes will be created with this template. |
+| `dhParamPath` | `./cert/dhparam.pem` | SSL dhparam path<sup>1</sup> (only need when you set `useSSL`) |
+| `sslCAPath` | `['./cert/COMODORSAAddTrustCA.crt']` | SSL ca chain<sup>1</sup> (only need when you set `useSSL`) |
+| `sslCertPath` | `./cert/codimd_io.crt` | SSL cert path<sup>1</sup> (only need when you set `useSSL`) |
+| `sslKeyPath` | `./cert/client.key` | SSL key path<sup>1</sup> (only need when you set `useSSL`) |
+| `tmpPath` | `./tmp/` | temp directory path<sup>1</sup> |
+| `docsPath` | `./public/docs` | docs directory path<sup>1</sup> |
+| `viewPath` | `./public/views` | template directory path<sup>1</sup> |
+| `uploadsPath` | `./public/uploads` | uploads directory<sup>1</sup> - needs to be persistent when you use imageUploadType `filesystem` |
+
+
+## CodiMD Location
+
+| variables | example values | description |
+| --------- | ------ | ----------- |
+| `domain` | `localhost` | domain name |
+| `urlPath` | `codimd` | sub URL path, like `www.example.com/<urlpath>` |
+| `host` | `localhost` | interface/ip to listen on |
+| `port` | `80` | port to listen on |
+| `path` | `/var/run/codimd.sock` | path to UNIX domain socket to listen on (if specified, `host` and `port` are ignored) |
+| `protocolUseSSL` | `true` or `false` | set to use SSL protocol for resources path (only applied when domain is set) |
+| `useSSL` | `true` or `false` | set to use SSL server (if `true`, will auto turn on `protocolUseSSL`) |
+| `urlAddPort` | `true` or `false` | set to add port on callback URL (ports `80` or `443` won't be applied) (only applied when domain is set) |
+| `allowOrigin` | `['localhost']` | domain name whitelist |
+
+
+## CSP and HSTS
+
+| variables | example values | description |
+| --------- | ------ | ----------- |
+| `hsts` | `{"enable": true, "maxAgeSeconds": 31536000, "includeSubdomains": true, "preload": true}` | [HSTS](https://en.wikipedia.org/wiki/HTTP_Strict_Transport_Security) options to use with HTTPS (default is the example value, max age is a year) |
+| `csp` | `{"enable": true, "directives": {"scriptSrc": "trustworthy-scripts.example.com"}, "upgradeInsecureRequests": "auto", "addDefaults": true}` | Configures [Content Security Policy](https://helmetjs.github.io/docs/csp/). Directives are passed to Helmet - see [their documentation](https://helmetjs.github.io/docs/csp/) for more information on the format. Some defaults are added to the configured values so that the application doesn't break. To disable this behaviour, set `addDefaults` to `false`. Further, if `usecdn` is on, some CDN locations are allowed too. By default (`auto`), insecure (HTTP) requests are upgraded to HTTPS via CSP if `useSSL` is on. To change this behaviour, set `upgradeInsecureRequests` to either `true` or `false`. |
+
+## Privacy and External Requests
+
+| variables | example values | description |
+| --------- | ------ | ----------- |
+| `allowGravatar` | `true` or `false` | set to `false` to disable gravatar as profile picture source on your instance |
+| `useCDN` | `true` or `false` | set to use CDN resources or not (default is `true`) |
+
+## Users and Privileges
+
+| variables | example values | description |
+| --------- | ------ | ----------- |
+| `allowAnonymous` | `true` or `false` | set to allow anonymous usage (default is `true`) |
+| `allowAnonymousEdits` | `true` or `false` | if `allowAnonymous` is `true`: allow users to select `freely` permission, allowing guests to edit existing notes (default is `false`) |
+| `allowFreeURL` | `true` or `false` | set to allow new note creation by accessing a nonexistent note URL |
+| `defaultPermission` | `freely`, `editable`, `limited`, `locked`, `protected` or `private` | set notes default permission (only applied on signed users) |
+| `sessionName` | `connect.sid` | cookie session name |
+| `sessionLife` | `14 * 24 * 60 * 60 * 1000` | cookie session life |
+| `sessionSecret` | `secret` | cookie session secret | If none is set, one will randomly generated on each startup, meaning all your users will be logged out. |
+
+
+## Login methods
+
+Most of these have never been documented for the config.json, feel free to expand these
+
+### Email (local account)
+
+| variables | example values | description |
+| --------- | ------ | ----------- |
+| `email` | `true` or `false` | set to allow email signin |
+| `allowEmailRegister`  | `true` or `false` | set to allow email register (only applied when email is set, default is `true`. Note `bin/manage_users` might help you if registration is `false`.) |

+Developer Notes
+===
+
+## Preparing for running the code
+
+**Notice:** *There's [specialised instructions for docker](../setup/docker.md) or [heroku](../setup/heroku.md), if you prefer running code this way!*
+
+1. Clone the repository with `git clone https://github.com/codimd/server.git codimd-server`
+   (cloning is the preferred way, but you can also download and unzip a release)
+2. Enter the directory and run `bin/setup`, which will install npm dependencies
+   and create configs. The setup script is written in Bash, you would need bash
+   as a prerequisite.
+3. Setup the [config file](../configuration-config-file.md) or set up
+   [environment variables](../configuration-env-vars.md).
+
+
+## Running the Code
+
+Now that everything is in place, we can start CodiMD:
+
+4. `npm run build` will build the frontend bundle. It uses webpack to do that.
+5. Run the server with `node app.js`
+
+
+## Running the Code with Auto-Reload
+
+The commands above are fine for production, but you're a developer and surely
+you want to change things. You would need to restart both commands whenever you
+change something. Luckily, you can run these commands that will automatically
+rebuild the frontend or restart the server if necessary.
+
+The commands will stay active in your terminal, so you will need multiple tabs
+to run both at the same time.
+
+4. Use `npm run dev` if you want webpack to continuously rebuild the frontend
+   code.
+5. To auto-reload the server, the easiest method is to install [nodemon](https://www.npmjs.com/package/nodemon)
+   and run `nodemon --watch app.js --watch lib --watch locales app.js`.
+
+
+## Structure
+
+The repository contains two parts: a server (backend) and a client (frontend).
+most of the server code is in `/lib` and most of the client code is in `public`.

+Webpack
+===
+
+Webpack is a JavaScript build system for frontend code. You can find out all
+about it on [the webpack website](https://webpack.js.org/).
+
+Here's how we're using it:
+
+## `webpack.common.js`
+This file contains all common definition for chunks and plugins, that are needed by the whole app.
+
+**TODO:** Document which entry points are used for what.
+
+## `webpack.htmlexport.js`
+Separate config for the "save as html" feature.
+Packs all CSS from `public/js/htmlExport.js` to `build/html.min.css`.
+This file is then downloaded by client-side JS and used to create the HTML.
+See `exportToHTML()` in `public/js/extra.js`.
+
+
+## `webpack.dev.js`
+The development config uses both common configs, enables development mode and enables "cheap" source maps (lines only).
+If you need more detailed source maps while developing, you might want to use the `source-maps` option.
+See https://webpack.js.org/configuration/devtool/ for details.
+
+## `webpack.prod.js`
+The production config uses both common configs and enables production mode.
+This automatically enables various optimizations (e.g. UglifyJS). See https://webpack.js.org/concepts/mode/ for details.
+
+For the global app config, the name of the emitted chunks is changed to include the content hash.
+See https://webpack.js.org/guides/caching/ on why this is a good idea.
+ 
+For the HTML export config, CSS minification is enabled.

+Keycloak/Red Hat SSO (self-hosted)
+===
+
+## Prerequisites
+
+This guide assumes you have run and configured Keycloak. If you'd like to meet this prerequisite quickly, it can be achieved by running a `jboss/keycloak` container and attaching it to your network. Set the environment variables KEYCLOAK_USER and `KEYCLOAK_PASSWORD`, and expose port 8080.
+
+Where HTTPS is specified throughout, use HTTP instead. You may also have to specify the exposed port, 8080.
+
+## Steps
+
+1. Sign in to the administration portal for your Keycloak instance at https://keycloak.example.com/auth/admin/master/console
+
+You may note that a separate realm is specified throughout this tutorial. It is best practice not to use the master realm, as it normally contains the realm-management client that federates access using the policies and permissions you can create.
+
+2. Navigate to the client management page at `https://keycloak.example.com/auth/admin/master/console/#/realms/your-realm/clients` (admin permissions required)
+3. Click **Create** to create a new client and fill out the registration form. You should set the Root URL to the fully qualified public URL of your CodiMD instance.
+4. Click **Save**
+5. Set the **Access Type** of the client to `confidential`. This will make your client require a client secret upon authentication.
+
+---
+
+### Additional steps to circumvent generic OAuth2 issue:
+
+1. Select Client Scopes from the sidebar, and begin to create a new client scope using the Create button.
+2. Ensure that the **Name** field is set to `id`.
+3. Create a new mapper under the Mappers tab. This should reference the User Property `id`. `Claim JSON Type` should be String and all switches below should be enabled. Save the mapper.
+4. Go to the client you set up in the previous steps using the Clients page, then choose the Client Scopes tab. Apply the scope you've created. This should mitigate errors as seen in [codimd/server#56](https://github.com/codimd/server/issues/56), as the `/userinfo` endpoint should now bring back the user's ID under the `id` key as well as `sub`.
+
+---
+
+6. In the `docker-compose.yml` add the following environment variables to `app:` `environment:`
+
+```
+CMD_OAUTH2_USER_PROFILE_URL=https://keycloak.example.com/auth/realms/your-realm/protocol/openid-connect/userinfo

+`CMD_LDAP_SEARCHFILTER` matches on all users and uses either the email address or the `sAMAccountName` (usually the login name you also use to login to Windows).
+
+*Only using `sAMAccountName` looks like this:* `(&(objectcategory=person)(objectclass=user)(sAMAccountName={{username}}))`
+

+
+`CMD_LDAP_PROVIDERNAME` just the name written above the username and password field on the login page.

+Authentication guide - Mattermost (self-hosted)
+===
+
+**Note:** *The Mattermost setup portion of this document is just a quick guide. See the [official documentation](https://docs.mattermost.com/developer/oauth-2-0-applications.html) for more details.*
+
+This guide uses the generic OAuth2 module for compatibility with Mattermost version 5.0 and above.
+
+1. Sign-in with an administrator account to your Mattermost instance
+2. Make sure **OAuth 2.0 Service Provider** is enabled in the Main Menu (menu button next to your username in the top left corner) --> System Console --> Custom Integrations menu, which you can find at `https://your.mattermost.domain/admin_console/integrations/custom`  
+   ![mattermost-enable-oauth2](../../images/auth/mattermost-enable-oauth2.png)
+
+3. Navigate to the OAuth integration settings through Main Menu --> Integrations --> OAuth 2.0 Applications, at `https://your.mattermost.domain/yourteam/integrations/oauth2-apps`
+4. Click on the **Add OAuth 2.0 Application** button to add a new OAuth application  
+   ![mattermost-oauth-app-add](../../images/auth/mattermost-oauth-app-add.png)

+
+*Note: The callback URL is \<your-codimd-url\>/auth/oauth2/callback*
+
+6. After saving the application, you'll receive the Client ID and Client Secret  
+   ![mattermost-oauth-app-done](../../images/auth/mattermost-oauth-app-done.png)

+
+This guide uses the generic OAuth2 module for compatibility with Nextcloud 13 and above (this guide has been tested successfully with Nextcloud 14).
+
+1. Sign-in with an administrator account to your Nextcloud server
+
+2. Navigate to the OAuth integration settings: Profile Icon (top right) --> Settings
+   Then choose Security Settings from the *Administration* part of the list - Don't confuse this with Personal Security Settings, where you would change your personal password!
+   At the top there's OAuth 2.0-Clients.  
+   ![Where to find OAuth2 in Nextcloud](../../images/auth/nextcloud-oauth2-1-settings.png)
+
+3. Add your CodiMD instance by giving it a *name* (perhaps CodiMD, but could be anything) and a *Redirection-URI*. The Redirection-URI will be `\<your-codimd-url\>/auth/oauth2/callback`. Click <kbd>Add</kbd>.

+Pad migration guide from etherpad-lite
+===
+
+The goal of this migration is to do a "dumb" import from all the pads in Etherpad, to notes in
+CodiMD. In particular, the url locations of the pads in Etherpad will be lost. Furthermore, any
+metadata in Etherpad, such as revisions, author data and also formatted text will not be migrated
+to CodiMD (only the plain text contents).
+
+Note that this guide is not really meant as a support guide. I migrated my own Etherpad to CodiMD,
+and it turned out to be quite easy in my opinion. In this guide I share my experience. Stuff may
+require some creativity to work properly in your case. When I wrote this guide, I was using
+[Etherpad 1.7.0] and [CodiMD 1.2.1]. Good luck!
+
+[Etherpad 1.7.0]: https://github.com/ether/etherpad-lite/tree/1.7.0
+[CodiMD 1.2.1]: https://github.com/codimd/server/tree/1.2.1
+
+## 0. Requirements
+
+- `curl`
+- running Etherpad server
+- running CodiMD server
+- [codimd-cli]
+
+[codimd-cli]: https://github.com/codimd/cli/blob/master/bin/codimd
+
+## 1. Retrieve the list of pads
+
+First, compose a list of all the pads that you want to have migrated from your Etherpad. Other than
+the admin interface, Etherpad does not have a dedicated function to dump a list of all the pads.
+However, the Etherpad wiki explains how to list all the pads by [talking directly to the
+database][howtolistallpads].
+
+You will end up with a file containing a pad name on each line:
+
+```
+date-ideas
+groceries
+london
+weddingchecklist
+(...)
+```
+
+[howtolistallpads]: https://github.com/ether/etherpad-lite/wiki/How-to-list-all-pads/49701ecdcbe07aea7ad27ffa23aed0d99c2e17db
+
+## 2. Run the migration
+
+Download [codimd-cli] and put the script in the same directory as the file containing the pad names.
+Add to this directory the file listed below, I called it `migrate-etherpad.sh`. Modify at least the
+configuration settings `ETHERPAD_SERVER` and `CODIMD_SERVER`.
+
+```shell
+#!/bin/sh
+
+# migrate-etherpad.sh
+#
+# Description: Migrate pads from etherpad to codimd
+# Author: Daan Sprenkels <hello@dsprenkels.com>

+# This script uses the codimd command line script[1] to import a list of pads from
+# [1]: https://github.com/codimd/cli/blob/master/bin/codimd
+
+# The base url to where etherpad is hosted
+ETHERPAD_SERVER="https://etherpad.example.com"
+
+# The base url where codimd is hosted
+CODIMD_SERVER="https://codimd.example.com"
+
+# Write a list of pads and the urls which they were migrated to

+
+Call this file like this:
+
+```shell
+./migrate-etherpad.sh pad_names.txt
+```
+
+This will download all the pads in `pad_names.txt` and put them on CodiMD. They will get assigned
+random ids, so you won't be able to find them. The script will save the mappings to a file though
+(in my case `redirects.txt`). You can use this file to redirect your users when they visit your
+etherpad using a `301 Permanent Redirect` status code (see the next section).
+
+## 3. Setup redirects (optional)
+
+I got a `redirects.txt` file that looked a bit like this:
+
+```
+date-ideas -> Found. Redirecting to https://codimd.example.com/mPt0KfiKSBOTQ3mNcdfn
+groceries -> Found. Redirecting to https://codimd.example.com/UukqgwLfhYyUUtARlcJ2_y

+weddingchecklist -> Found. Redirecting to https://codimd.example.com/XcQGqlBjl0u40wfT0N8TzQ
+(...)
+```
+
+Using some `sed` magic, I changed it to an nginx config snippet:
+
+```
+location = /p/date-ideas {
+    return 301 https://codimd.example.com/mPt0M1KfiKSBOTQ3mNcdfn;
+}
+location = /p/groceries {
+    return 301 https://codimd.example.com/UukqgwLfhYyUUtARlcJ2_y;

+}
+location = /p/weddingchecklist {
+    return 301 https://codimd.example.com/XcQGqlBjl0u40wfT0N8TzQ;
+}
+```
+
+I put this file into my `etherpad.example.com` nginx config, such that all the users would be
+redirected accordingly.

+Migrations and Notable Changes
+===
+
+## Migrating to 1.4.0
+
+We dropped support for node 6 with this version. If you have any trouble running this version, please double check that you are running at least node 8!
+
+## Migrating to 1.3.2
+
+This is not a breaking change, but to stay up to date with the community
+repository, you may need to update a few urls. This is not a breaking change.
+
+See more at [issue #10](https://github.com/codimd/server/issues/10)
+
+**Native setup using git:**
+
+Change the upstream remote using `git remote set-url origin https://github.com/codimd/server.git`.
+
+**Docker:**
+
+When you use our [container repository](https://github.com/codimd/container) 
+(which was previously `codimd-container`) all you can simply run `git pull` and
+your `docker-compose.yml` will be updated.
+
+When you setup things yourself, make sure you use the new image:
+[`quay.io/codimd/server`](https://quay.io/repository/codimd/server?tab=tags).
+
+**Heroku:**
+
+All you need to do is [disconnect GitHub](https://devcenter.heroku.com/articles/github-integration#disconnecting-from-github)
+and [reconnect it](https://devcenter.heroku.com/articles/github-integration#enabling-github-integration)
+with this new repository.
+
+Or you can use our Heroku button and redeploy your instance and link the old
+database again.
+
+## Migrating to 1.1.0
+
+We deprecated the older lower case config style and moved on to camel case style. Please have a look at the current `config.json.example` and check the warnings on startup.
+
+*Notice: This is not a breaking change right now but will be in the future*
+
+## Migrating to 0.5.0
+
+[migration-to-0.5.0 migration tool](https://github.com/hackmdio/migration-to-0.5.0)
+
+We don't use LZString to compress socket.io data and DB data after version 0.5.0.
+Please run the migration tool if you're upgrading from the old version.
+
+## Migrating to 0.4.0
+
+[migration-to-0.4.0 migration tool](https://github.com/hackmdio/migration-to-0.4.0)
+
+We've dropped MongoDB after version 0.4.0.
+So here is the migration tool for you to transfer the old DB data to the new DB.
+This tool is also used for official service.

+History of CodiMD
+===
+
+## It started with HackMD
+
+HackMD is the origin of this project, which was mostly developed by Max Wu and
+Yukai Huang. Originally, this was open source under MIT license, but was
+[relicensed in October 2017 to be AGPLv3](https://github.com/hackmdio/codimd/pull/578).
+At the same time, [hackmd.io](https://hackmd.io) was founded to offer a
+commercial version of HackMD.
+
+The AGPLv3-version was developed and released by the community, this was for a
+while referred to as "HackMD community edition".
+
+*For more on the splitting of the projects, please refer to [A note to our community (2017-10-11)](https://hackmd.io/c/community-news/https%3A%2F%2Fhackmd.io%2Fs%2Fr1_4j9_hZ).*
+
+
+## HackMD CE became CodiMD
+
+In June 2018, CodiMD was renamed from its former name "HackMD" and continued to
+be developed under AGPLv3 by the community. We decided to change the name to
+break the confusion between HackMD (enterprise offering) and CodiMD (community
+project), as people mistook it for an open core development model.
+
+*For the whole renaming story, see the [issue where the renaming was discussed](https://github.com/hackmdio/hackmd/issues/720).*
+
+
+## CodiMD went independent
+
+In March 2019, a discussion over licensing, governance and the future of CodiMD
+lead to the formation of a distinct GitHub organization. Up to that point, the
+community project resided in the organization of hackmdio but was for the most
+part self-organized.
+
+During that debate, we did not reach an agreement that would have allowed us to
+move the repository, so we simply forked it. We still welcome the HackMD team
+as part of our community, especially since a large portion of this code base
+originated with them.
+
+*For the debate that lead to this step, please refer to the [governance debate](https://github.com/hackmdio/hackmd/issues/1170) and [the announcement of the new repository](https://github.com/codimd/server/issues/10).*

+
+[LinuxServer.io](https://linuxserver.io) have created an Ubuntu-based multi-arch container image for x86-64, arm64 and armhf which supports PDF export from all architectures using [PhantomJS](https://phantomjs.org/).
+
+- It supports all the environment variables detailed in the [configuration documentation](../configuration-env-vars.md) to modify it according to your needs.
+
+- It gets rebuilt on new releases from CodiMD and also weekly if necessary to update any other package changes in the underlying container, making it easy to keep your CodiMD instance up to date.

+Manual Installation
+===
+
+## Requirements on your server
+
+- Node.js 8.5 or up
+- Database (PostgreSQL, MySQL, MariaDB, SQLite, MSSQL) use charset `utf8`
+- npm (and its dependencies, [node-gyp](https://github.com/nodejs/node-gyp#installation))
+- yarn
+- Bash (for the setup script)
+- For **building** CodiMD we recommend to use a machine with at least **2GB** RAM
+
+
+## Instructions
+
+1. Check if you meet the [requirements at the top of this document](#requirements-on-your-server).
+2. Clone this repository (preferred) or download a release and unzip it.
+3. Enter the directory and type `bin/setup`, which will install npm dependencies and create configs.
+4. Setup the configs, see more below
+5. Setup environment variables which will overwrite the configs
+6. Build front-end bundle by `npm run build` (use `npm run dev` if you are in development)
+7. Modify the file named `.sequelizerc`, change the value of the variable `url` with your db connection string
+   For example: `postgres://username:password@localhost:5432/codimd`
+8. It is recommended to start your server manually once: `npm start --production`, this way it's easier to see warnings or errors that might occur (leave out `--production` for development).
+9. Run the server as you like (node, forever, pm2, SystemD, Init-Scripts)
+
+
+## How to upgrade your installation
+
+If you are upgrading CodiMD from an older version, follow these steps:
+
+1. Check if you meet the [requirements at the top of this document](#requirements-on-your-server).
+2. Verify which version you were running before and take a look at [migrations and breaking changes](../guides/migrations-and-breaking-changes.md) to see if additional steps, or configuration changes are necessary!
+3. Fully stop your old CodiMD server.
+4. `git pull` or unzip a new release in the directory.
+5. Run `bin/setup`. This will take care of installing dependencies. It is safe to run on an existing installation.
+6. Build front-end bundle by `npm run build` (use `npm run dev` if you are in development).
+7. It is recommended to start your server manually once: `npm start --production`, this way it's easier to see warnings or errors that might occur (leave out `--production` for development).
+8. You can now restart the CodiMD server!

+Slide Separators
+===
+
+If you're getting started with reveal.js slides, there are a few things you need to know.
+
+There are two types of slides, those that transition horizontally and those that transition vertically (subslides).
+
+The following separators are used for each in the CodiMD syntax:
+```
+# First Slide
+
+---
+
+# Next slide
+
+----
+
+## Subslide
+```
+as you can see, horizontal transitions are separated by `---` and vertical transitions by `----`
+
+## Basic YAML header
+It's possible to customise the slide options using the YAML header in the slide markdown.
+
+eg:
+```
+---
+title: Example Slide
+tags: presentation
+slideOptions:
+  theme: solarized
+  transition: 'fade'
+  # parallaxBackgroundImage: 'https://s3.amazonaws.com/hakim-static/reveal-js/reveal-parallax-1.jpg'
