-Part from [damp11113](https://github.com/damp11113/damp11113-library)
+# What is PyserSSH
+
+PyserSSH is a library for remote control your code with ssh client. The aim is to provide a scriptable SSH server which can be made to behave like any SSH-enabled device.
+
+This project is part from [damp11113-library](https://github.com/damp11113/damp11113-library)
+
+This Server use port **2222** for default port
+
+# Install
+Install from pypi
+```bash
+pip install PyserSSH
+```
+Install from github
+```bash
+pip install git+https://github.com/damp11113/PyserSSH.git
+```
+# Quick Example
+```py
+import os
+
+from PyserSSH import Server, Send, AccountManager
+
+useraccount = AccountManager()
+useraccount.add_account("admin", "") # create user without password
+
+ssh = Server(useraccount)
+
+@ssh.on_user("command")
+def command(channel, command: str, client):
+    if command == "hello":
+        Send(channel, "world!")
+        
+ssh.run(os.path.join(os.path.dirname(os.path.realpath(__file__)), 'private_key.pem'))
+```
+This example you can connect with `ssh admin@localhost -p 2222` and press enter on login
+If you input `hello` the response is `world`
 
 # Demo
 See [server.py](https://github.com/damp11113/PyserSSH/blob/main/demo/server.py)
 
 I intend to leaked private key because that key i generated new. I recommend to generate new key if you want to use on your host because that key is for demo only.
+why i talk about this? because when i push private key into this repo in next 5 min++ i getting new email from GitGuardian. in that email say "
+GitGuardian has detected the following RSA Private Key exposed within your GitHub account" i dont knows what is GitGuardian and i not install this app into my account.
