-**Additional Features**
-- If you want to use unsafe 'password' feature you must install `sshpass` first.
-- If you want to use bash autocompletion function with sshch, copy autocompletion script to /etc/bash_completion.d/:
-```bash
-sudo cp completion/sshch_bash_completion.sh /etc/bash_completion.d/sshch
+If you want to use bash autocompletion function with sshch, copy autocompletion script to /etc/bash_completion.d/:
+```
+sudo cp sshch_bash_completion.sh /etc/bash_completion.d/sshch
 ```
 (changes will come into effect with new bash session)
-- If you want to use zsh autocompletion:
-1) Place File in a Directory where ZSH can find it
-
-     -> Search Path is Stored in $fpath
-
-     -> echo $fpath
-2) Rename File to '_sshch'
