Implemented .ssh/config indexing

Unfortunately I had to make iTerm2 a hard dependency. Please check the README.md for more info on that. If you know another way to implement this without depending on one specific terminal, feel free to PR!

@@ -5,6 +5,10 @@ SSH (LaunchBar Action)
 
 This **SSH** action allows you quickly connect to previously used ssh connections. Therefor it reads your `.zsh_history` and your `.bash_history` and gives you a list of all available ssh connections. Fuzzy search on that list is available as well.
 
+## Requirements
+
+Because it seems to be impossible to teach MacOS's `ssh://` URL functionality to open hosts defined within `.ssh/config`, this action unfortunately depends on [iTerm2](https://www.iterm2.com) and its integration into LaunchBar. Make sure you have iTerm2 installed and the LaunchBar Action `Run iTerm Command` is available to you. You can check that by invoking LaunchBar and type `Run`.
+
 ## Installation
 
 Clone/download this repository's master and double-click *SSH.lnbaction*. LaunchBar will then prompt you, whether you want to install it.
