-# Libretro Docs
+# Contribute to the documentation
 
-WIP.
+The docs are written in [Markdown](https://en.wikipedia.org/wiki/Markdown) if you need help with the syntax use [this guide](https://guides.github.com/features/mastering-markdown/). Mkdocs uses some [Markdown extensions](http://www.mkdocs.org/user-guide/writing-your-docs/#markdown-extensions) that you may have to familiarize with.
+
+The documentation source is maintained via [Git](https://en.wikipedia.org/wiki/Git). For more info on how to use git [refer to their help](https://help.github.com/)
+
+In order to propose improvements to a document:
+
+1. [Clone the repo](https://github.com/libretro/docs)
+2. Make the changes and update your clone
+3. Follow the "Building the docs" section to render the documentation site locally
+4. Propose your changes using the button `New Pull Request` [in the docs repo](https://github.com/libretro/docs)
+
+There is a To-Do list for libretro/docs [here](todo.md) and you can submit suggestions or issues regarding documentation at the [libretro/docs issue tracker](https://github.com/libretro/docs/issues).
+
+## Building the docs
+
+1. Make sure you have [Python](https://www.python.org/) and [pip](https://pip.pypa.io) installed
+    ```
+    python --version
+    pip --version
+    ```
+
+!!! Note "Building in Windows/msys2"
+    If you are using the standard RetroArch msys2 environment, you will need to install python with the command `pacman -S python`. Next you will need to download [the `get-pip.py` script](https://bootstrap.pypa.io/get-pip.py) from the `pip` bootstrap site. Finally, execute the script with the command `python get-pip.py`.
+
+2. Install MkDocs
+    ```
+    pip install mkdocs
+    ```
+
+3. Install MkDocs-Material
+    ```
+    pip install mkdocs-material
+    ```
+
+4. Install PyMdown Extensions
+    ```
+    pip install pymdown-extensions
+    ```
+
+5. Build the site
+    ```
+    mkdocs build
+    ```
+
+6. The documentation will be built to the `site` directory; preview any changes with MkDocs' built-in dev-server before submitting a pull request
+    ```
+    mkdocs serve
+    ```
