 ## Building
 
-(TODO)
+To build the website, install the dependencies and run the build script:
+```sh
+npm install
+npm run build
+```
+The output will be in `_site`.

+You can also start a development server with auto-reloading:
+```sh
+npm run start
+```
 
 ## Nix DevShell
 A nix development shell that provides all required tools for developing and building the project is provided for convenience. Using it is by no means required, although we encourage it.
