 Building from source:
 
 ```bash
-make build
+make install PREFIX=~/.local
 ```
 
-This assumes the assets used by the website (e.g. the CSS files) are located at

+uninstall, run the following:
+
+```bash
+make uninstall PREFIX=~/.local

+For testing changes locally, run the following
 
 ```bash
 make build ASSETS=$PWD/assets
 ```
 
-You can also use the provided Docker image:
