+# mikroskeem's AUR build bot
+
+NOTE: This is actually not ready, so it is not recommended to run it in production (don't be like me!)
+
+## Installing
+
+* Set up new Arch Linux nspawn container (I recommend using this [script](https://gist.github.com/artizirk/fab2ce13277a190ee6063b03b8e0a6e9) made by @artizirk)
+* Install [aurutils](https://aur.archlinux.org/packages/aurutils) and set it up
+* Copy `buildpkg` to `/usr/bin` in builder container
+* Set up [OpenSMTPD](https://wiki.archlinux.org/index.php/OpenSMTPD) server on container and host (to send emails to builder in case of failure)
+    - Note: Don't forget to firewall!
+* Copy `aur` script to `/usr/bin` in host machine
+* Set up nginx to serve packages to host (and maybe for public)
+
+## Known issues
+* You can't edit PKGBUILD-s
+* You can't accept GPG keys automatically (insecure to do so, but you can do `gpg --recv-key <key>` in container shell)
+* Not documentated enough!
+* Probably something more I'm not currently aware of
