+# SSH-HUB - portable command hub
+
+## Autocompletion
+In order to create autocompletion you have to:
+- Download executable or clone project and write go install
+- Then consult with ssh-hub completion. There you can select needed script for your terminal
+- After that source it to have autocompletion and you are ready to go
+
+
+Example in Mac OS with ZSH:
+- go build
+- go install
+- ssh-hub completion zsh > ssh-hub-completion.zsh
+- source ssh-hub-completion.zsh
+- Now you should have it! Try using a ssh-hub exec [TAB] [TAB] it will help to find needed command
