 * Install package as usual.
-* Change settings if required, see `CONFIGURING.md` for more details.
-* Create `/var/lib/ahriman/.makepkg.conf` with `makepkg.conf` overrides if required (at least you might want to set `PACKAGER`).
-* Configure build tools (it might be required if your package will use any custom repositories):
-    * create build command, e.g. `ln -s /usr/bin/archbuild /usr/local/bin/custom-x86_64-build` (you can choose any name for command);
-    * create configuration file, e.g. `cp /usr/share/devtools/pacman-{extra,custom}.conf`;
