+## Building a Package from Source
+
+### Arch Linux
+
+Use the PKGBUILD under `pkg/arch`, i.e. to build a pakcage and directly install it run 
+```
+cd pkg/arch && makepkg -fsi
+```
+
+### Debian/Ubuntu
+
+Use the `makedeb` script provided under `pkg/deb`, i.e. run
+```
+./pkg/deb/makedeb
+```
+from the root project directory.
+You may need to install the `build-essential` and `devscripts` packages beforehand.
+The final package will be in the `pkg/deb` directory.
