+# API documentation
+Several tasks of HedgeDoc can be automated through HTTP requests.
+The available endpoints for this api are described in this document.
+For code-autogeneration there is an OpenAPIv3-compatible description available [here](openapi.yml).
+
+## Notes
+These endpoints create notes, return information about them or export them.
+You have to replace *\<NOTE\>* with either the alias or id of a note you want to work on.
+
+| Endpoint | HTTP-Method | Description |
+| ---------------------------------------------- | ----------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
+| `/new` | `GET` | **Creates a new note.**<br>A random id will be assigned and the content will equal to the template (blank by default). After note creation a redirect is issued to the created note. |
+| `/new` | `POST` | **Imports some markdown data into a new note.**<br>A random id will be assigned and the content will equal to the body of the received HTTP-request. The `Content-Type: text/markdown` header should be set on this request. |
+| `/new/<ALIAS>` | `POST` | **Imports some markdown data into a new note with a given alias.**<br>This endpoint equals to the above one except that the alias from the url will be assigned to the note if [FreeURL-mode](../configuration.md#users-and-privileges) is enabled. |
+| `/<NOTE>/download` or `/s/<SHORT-ID>/download` | `GET` | **Returns the raw markdown content of a note.** |
+| `/<NOTE>/publish` | `GET` | **Redirects to the published version of the note.** |
+| `/<NOTE>/slide` | `GET` | **Redirects to the slide-presentation of the note.**<br>This is only useful on notes which are designed to be slides. |
+| `/<NOTE>/info` | `GET` | **Returns metadata about the note.**<br>This includes the title and description of the note as well as the creation date and viewcount. The data is returned as a JSON object. |
+| `/<NOTE>/revision` | `GET` | **Returns a list of the available note revisions.**<br>The list is returned as a JSON object with an array of revision-id and length associations. The revision-id equals to the timestamp when the revision was saved. |
+| `/<NOTE>/revision/<REVISION-ID>` | `GET` | **Returns the revision of the note with some metadata.**<br>The revision is returned as a JSON object with the content of the note and the authorship. |
+| `/<NOTE>/gist` | `GET` | **Creates a new GitHub Gist with the note's content.**<br>If [GitHub integration](../configuration.md#github-login) is configured, the user will be redirected to GitHub and a new Gist with the content of the note will be created. |
+
+## User / History
+These endpoints return information about the current logged-in user and it's note history. If no user is logged-in, the most of this requests will fail with either a HTTP 403 or a JSON object containing `{"status":"forbidden"}`.
+
+| Endpoint | HTTP-Method | Description |
+| ----------------- | ----------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| `/me` | `GET` | **Returns the profile data of the current logged-in user.**<br>The data is returned as a JSON object containing the user-id, the user's name and a url to the profile picture. |
+| `/me/export` | `GET` | **Exports a zip-archive with all notes of the current user.** |
+| `/history` | `GET` | **Returns a list of the last viewed notes.**<br>The list is returned as a JSON object with an array containing for each entry it's id, title, tags, last visit time and pinned status. |
+| `/history` | `POST` | **Replace user's history with a new one.**<br>The body must be form-encoded and contain a field `history` with a JSON-encoded array like its returned from the server when exporting the history. |
+| `/history` | `DELETE` | **Deletes the user's history.** |
+| `/history/<NOTE>` | `POST` | **Toggles the pinned status in the history for a note.**<br>The body must be form-encoded and contain a field `pinned` that is either `true` or `false`. |
+| `/history/<NOTE>` | `DELETE` | **Deletes a note from the user's history.** |
+
+## HedgeDoc-server
+These endpoints return information about the running HedgeDoc instance.
+
+| Endpoint | HTTP-Method | Description |
+| --------- | ----------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| `/status` | `GET` | **Returns the current status of the HedgeDoc instance.**<br>The data is returned as a JSON object containing the number of notes stored on the server, (distinct) online users and more. |

+# Documentation
+
+Our documentation is build with [mkdocs](https://www.mkdocs.org).
+
+## Writing
+
+All documentation files are found in the `docs/content` directory of the [hedgedoc/hedgedoc repo](https://github.com/hedgedoc/hedgedoc). These files are just normal markdown files with nothing special about them.
+
+The configuration for mkdocs lies in the `docs` folder in a file called `mkdocs.yml`. With that file the theme and menu - amoung others - can be configured.
+**Please note:** Any new files need to be linked to by other files or put in the navigation or the files will be very hard to find on the documentation website.
+
+## Building
+
+To build the documentation locally you need to perform the following steps:
+
+0. Make sure you have python3 installed.
+1. Go into the `docs` folder.
+2. Install all the dependencies (E.g. with a [venv](https://docs.python.org/3/library/venv.html)) with `pip install -r requirements.txt`
+3. Start the mkdocs dev server (`mkdocs serve`) or build the documentation (`mkdocs build`).
+
+## Deployment
+
+The documentation is deployed with [Messor Structor](https://github.com/traefik/structor).
+
+The necessary Dockerfile and version menu template and also the github action to build the whole documentation can be found in the [docs.hedgedoc.org repo](https://github.com/hedgedoc/docs.hedgedoc.org). This repo is also used to deploy the actuall website to github.io.
+
+Messor Structor builds and deploys the documentation by finding all branches that follow the pattern `v*`. For each branch the docs are generated separately by first installing the dependencies from `requirements.txt` and then running mkdocs. Afterwards the menu go template is used to include a version switcher in the theme.

+# Getting started
+
+## 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/hedgedoc/hedgedoc.git hedgedoc-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.md) or set up
+ [environment variables](../configuration.md).
+
+## Running the Code
+
+Now that everything is in place, we can start HedgeDoc:
+
+1. `yarn run build` will build the frontend bundle. It uses webpack to do that.
+2. 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.
+
+1. Use `yarn run dev` if you want webpack to continuously rebuild the frontend
+ code.
+
+2. 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 definitions for chunks and plugins that are needed by the whole app.
+
+The various entrypoints under the `entry` key define groups of files (npm packages or .css/.js files directly from this project) that need to be included together to be useful.
+The `index` group for example bundles all javascript files and libraries used for the note editor.
+
+Entrypoints are referenced in the `plugins` section.
+The `HtmlWebpackPlugin` uses templates in `public/views/includes` to include the path to the generated resources in new templates under `public/views/build`. These templates are then used by the backend to serve HTML to the browser.
+
+**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.
