 # ArcHlinux ReposItory MANager
 
+[![build status](https://github.com/arcan1s/ahriman/actions/workflows/run-tests.yml/badge.svg)](https://github.com/arcan1s/ahriman/actions/workflows/run-tests.yml)
+
 Wrapper for managing custom repository inspired by [repo-scripts](https://github.com/arcan1s/repo-scripts).
 
 ## Features
 
 * Install-configure-forget manager for own repository
+* Multi-architecture support
 * VCS packages support
-* Sign support with gpg
-* Synchronization to remote services and report generation 
+* Sign support with gpg (repository, package, per package settings)
+* Synchronization to remote services (rsync, s3) and report generation (html)
+* Dependency manager
 * Repository status interface
 
 ## Installation and run
 
 * 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 if required, 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`;
-    * change configuration file: add your own repository, add multilib repository;
-    * set `build.build_command` to point to your command;
-    * configure `/etc/sudoers.d/ahriman` to allow to run command without password.
-* Start and enable `ahriman.timer` via `systemctl`.
-* Add packages by using `ahriman add {package}` command.
+* Change settings if required, see [CONFIGURING](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`):
 
-## Limitations
+    ```shell
+    echo 'PACKAGER="John Doe <john@doe.com>"' | sudo -u ahriman tee -a /var/lib/ahriman/.makepkg.conf
+    ```
 
-* It does not manage dependencies, so you have to add them before main package.
+* Configure build tools (it is required for correct dependency management system):
+
+    * create build command, e.g. `ln -s /usr/bin/archbuild /usr/local/bin/ahriman-x86_64-build` (you can choose any name for command, basically it should be `{name}-{arch}-build`);
+    * create configuration file, e.g. `cp /usr/share/devtools/pacman-{extra,ahriman}.conf` (same as previous `pacman-{name}.conf`);
+    * change configuration file, add your own repository, add multilib repository etc;
+    * set `build_command` option to point to your command;
+    * configure `/etc/sudoers.d/ahriman` to allow running command without a password.
+
+    ```shell
+    ln -s /usr/bin/archbuild /usr/local/bin/ahriman-x86_64-build
+    cp /usr/share/devtools/pacman-{extra,ahriman}.conf
+
+    echo '[multilib]' | tee -a /usr/share/devtools/pacman-ahriman.conf
+    echo 'Include = /etc/pacman.d/mirrorlist' | tee -a /usr/share/devtools/pacman-ahriman.conf
+
+    echo '[aur-clone]' | tee -a /usr/share/devtools/pacman-ahriman.conf
+    echo 'SigLevel = Optional TrustAll' | tee -a /usr/share/devtools/pacman-ahriman.conf
+    echo 'Server = file:///var/lib/ahriman/repository/$arch' | tee -a /usr/share/devtools/pacman-ahriman.conf
+
+    echo '[build]' | tee -a /etc/ahriman.ini.d/build.ini
+    echo 'build_command = ahriman-x86_64-build' | tee -a /etc/ahriman.ini.d/build.ini
+
+    echo 'Cmnd_Alias CARCHBUILD_CMD = /usr/local/bin/ahriman-x86_64-build *' | tee -a /etc/sudoers.d/ahriman
+    echo 'ahriman ALL=(ALL) NOPASSWD: CARCHBUILD_CMD' | tee -a /etc/sudoers.d/ahriman
+    chmod 400 /etc/sudoers.d/ahriman
+    ```
+
+* Start and enable `ahriman@.timer` via `systemctl`:
+
+    ```shell
+    systemctl enable --now ahriman@x86_64.timer
+    ```
+
+* Start and enable status page:
+
+    ```shell
+    systemctl enable --now ahriman-web@x86_64
+    ```
+
+* Add packages by using `ahriman add {package}` command:
+
+    ```shell
+    sudo -u ahriman ahriman -a x86_64 add yay --now
+    ```
+
+Note that initial service configuration can be done by running `ahriman setup` with specific arguments.
