+# Usage
+## Installation
+To install StartTree for the first time, run the following commands:  
+(Note: If the `~/.config/StartTree` directory already exists, `init.py` will not execute to prevent accidentally overwriting a custom config. )
+```
+git clone https://github.com/Paul-Houser/StartTree.git
+cd StartTree
+./init.py
+./generate.py
+```
+This will create the directory `~/.config/StartTree` containing the default `config.yaml`, as well as generate the html/css, which you can view by pointing your browser at `$HOME/.cache/StartTree/index.html`.
 
+## Config
+The config should be placed in `~/.config/StartTree/config.yaml`
+
+## Updating the HTML
+To re-generate the html/css after editing the config, navigate to the `StartTree` directory and execute `./generate.py`.
+
+# Example Config
