+# Guide to Merlin Documentation
+
+Merlin uses [MkDocs](https://www.mkdocs.org/) to generate its documentation and [Read the Docs](https://about.readthedocs.com/?ref=readthedocs.com) to host it. This README will detail important information on handling the documentation.
+
+## How to Build the Documentation
+
+Ensure you're at the root of the Merlin repository:
+
+```bash
+cd /path/to/merlin/
+```
+
+Install the documentation with:
+
+```bash
+pip install -r docs/requirements.txt
+```
+
+Build the documentation with:
+
+```bash
+mkdocs serve
+```
+
+Once up and running, MkDocs should provide a message telling you where your browser is connected (this is typically `http://127.0.0.1:8000/`). If you're using VSCode, you should be able to `ctrl+click` on the address to open the browser window. An example is shown below:
+
+```bash
+(venv_name) [user@machine:merlin]$ mkdocs serve
+INFO    -  Building documentation...
+INFO    -  Cleaning site directory
+WARNING -  Excluding 'README.md' from the site because it conflicts with 'index.md'.
+WARNING -  A relative path to 'api_reference/' is included in the 'nav' configuration, which is not found in the documentation files.
+INFO    -  Documentation built in 3.24 seconds
+INFO    -  [09:16:00] Watching paths for changes: 'docs', 'mkdocs.yml'
+INFO    -  [09:16:00] Serving on http://127.0.0.1:8000/
+```
+
+## Configuring the Documentation
+
+MkDocs relies on an `mkdocs.yml` file for almost everything to do with configuration. See [their Configuration documentation](https://www.mkdocs.org/user-guide/configuration/) for more information.
+
+## How Do API Docs Work?
