 For non-ruby folks. Needs `ruby` and `zlib` development headers (on Debian: `apt-get install ruby-dev zlib1g-dev`).
 
+Use e.g. rvm to manage ruby versions. Do `rvm install "ruby-2.5.7"` to install the appropiate ruby version. Run `rvm use` then and check with `ruby --version` if it was properly activated. (If ruby complains about not using a login shell run `source ~/.rvm/scripts/rvm`)

+You may then install dependencies and build with: 
 ```bash
-$ export GEM_HOME=~/.gem
 $ gem install bundler rake
-$ ~/.gem/bin/bundle
+$ bundle install
 $ rake build
+```
+
+You can install the vagrant plugin then with `vagrant plugin install ./vagrant-proxmox-0.2.2.gem` (you might run into problems if you run it on a shell where you ran `rvm use` previously).

+Optionally run the rspec tests with `rake spec`. (Make sure, that vagrant is installed in the ruby env you are using.)
