+
+## Setup
+
+`yaourt` is used as an example AUR helper, use whichever you like or do it manually. Prefixed with `#` means run as root, prefixed with `$` means run as the user you regularly work with.
+
+```bash
+# pacman -S ruby
+$ yaourt -S chruby ruby-bundler
+$ mkdir -p ~/.rubies/2.2/bin
+$ ln -s /usr/bin/ruby ~/.rubies/2.2/bin/ruby
+$ echo "gem: --no-user-install --env-shebang" > ~/.gemrc
+```
+
+Edit your `~/.$SHELLrc` and add:
+
+```bash
+# chruby
+source /usr/share/chruby/chruby.sh
+source /usr/share/chruby/auto.sh
+RUBIES=(/opt/ruby* $HOME/.rubies/*)
+```
+
+Optionally, but the entire point of this setup, install older Ruby versions:
+
+```bash
+$ yaourt -S ruby2.1 ruby2.0 ruby2.1-bundler ruby2.0-bundler
+```

+
+Most likely I will upload a package for the old release to the AUR:
+
+```bash
+$ yaourt -S ruby2.2
+```
+
+## Per project setup
+
+Create a `.ruby-version` file with the desired version to use, like
+
+```
+2.2
+```
+
+Use a `Gemfile` and `bundle install` to install gems into your home folder, or `bundle install --path vendor/bundle` to install gems to a per project directory.
+
+
+## System wide gem installation
+
+Do not do `gem install as root, install the packages from the AUR like we already did for `ruby-bundler`, `ruby2.1-bundler` and so on.

+
+## Scripting
+
+Use `/usr/bin/chruby-exec 2.1 -- regular command` to switch to a different Ruby environment in your scripts. This only works for scripts run as users that have this setup. Same holds true for systemd units, while you can use `chruby-exec` in `ExecStart` and friends, your service needs to have a `User=` to one with this setup.
