-Simpe python script for fast access to ssh hosts.
+SSH connection and aliases manager with curses and command line interface
+======
+sshch is released under DWTWL 2.55 license
 
-under DWTWL 2.5 license: https://soundragon.su/license/license.html
+sshch compatible with pyhon2 and python3, no additional libraries are required
+### Screenshot
+![sshch](https://raw.githubusercontent.com/zlaxy/sshch/master/sshch_screenshot.png)
+### Installing
+**You can install a release version from pip:**
+```bash
+pip install sshch
+```
+**Manual installation from the package or git repository also available:**
+
+To install for all users:
+```bash
+sudo python setup.py install
+```
+To install just for current user:
+```bash
+mkdir ~/.local/bin
+cp sshch/sshch ~/.local/bin/
+```
+### Using
+To run curses interface:
+```bash
+sshch
+```
+To run command line help:
+```bash
+sshch -h
+```
+For exit from current ssh session press `Ctrl+D`.
+
+**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
+```
+(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'
