 # obsidian-workflow-template-docs
+
 This is the documentation for my [obsidian-workflow-template](https://github.com/mathisgauthey/obsidian-workflow-template) project.
+
+## Technology used
+
+I'm using [MkDocs](https://www.mkdocs.org/) with the [Material theme](https://squidfunk.github.io/mkdocs-material/).
+
+It has a wonderful documentation and is very customizable.
+
+## Requirements
+
+```bash
+pip install mkdocs
+pip install mkdocs-material
+```
+
+Don't forget the `sudo` before on linux, otherwise you might run into possible errors related to `command not found`.
+
+## Usage
+
+MkDocs includes a live preview server, so you can preview your changes as you write your documentation. The server will automatically rebuild the site upon saving. Start it with:
+
+```bash
+mkdocs serve
+```
+
+When you're finished editing, you can build a static site from your Markdown files with:
+
+```bash
+mkdocs build
+```
