+
+```conf
+[grawlinson]
+Server = file:///var/lib/repo/grawlinson

- build   build specified package(s) and add to local repo [default:all]
- check   use nvchecker to check for new package versions
- clean   remove old packages from local repo
- remove  remove specified package(s) from local repo
- sync    sync local repo with remote repo
+
+* Ensure GPG keys for signing packages & repositories have been created,
+ and exist in pacman's keyring.
+
+* Copy aurutils configuration to the global directory.
+
+```sh
+cp -t /etc/aurutils {pacman,makepkg}-grawlinson.conf
 ```
 
+* Create a `systemd-nspawn` instance for aurbuild.
+
+```sh
+aur chroot --create \
+  -M /etc/aurutils/makepkg-grawlinson.conf \
+  -C /etc/aurutils/pacman-grawlinson.conf
+```
+
+## Usage
+
+* `make check`: Check for new package versions.
+* `make sync` : Sync local repository with remote.
+* `make` for the rest of the commands.
+
+### Building a new or updated package
+
+```sh
+sh .repo/build [packages ...]
+```
+
+A wrapper around [aurutils][url-aurutils], builds package(s) specified in a
+clean chroot. After successful build, packages are added to the repository
+and old versions are removed. By default, packages and repository database
+are signed.
+
+### Removal
+
+```sh
+sh .repo/remove [packages ...]
+rm -f /var/lib/repo/$REPO/{packages,and,signatures,to,delete}
+```
+
+Removal of package(s) from the repository is invoked via the `.repo/remove`
+script (shown above). Actual deletion of the package(s) (and the
+corresponding package signatures) is to be done manually.
