+## 🔵 <a name="check-works"></a> Checking if SSHScript works
+
+SSHScript works in two ways: SSHScript dollar-syntax and python module.
+
+### SSHScript dollar-syntax
+
+SSHScript adds additional syntax that could used in regular python statements.
+Because those additional syntax are started with $(dollar), so it is called dollar-syntax.
+
+A python script with dollar-syntax is excuted by the SSHScript CLI "sshscript" command.
+
+For example:
+```
+$hostname
+print($.stdout.strip())
+```
+This two-lines example would execute command "hostname" and print the output on stdout.
+To run it, please save it as "example.spy", then in the console, runs:
+```
+sshscript example.spy
+```
+
+### SSHScript module
+
+SSHScript v2.0 has refined the functionality of module for users who can use sshscript without written syntax-dollar.
+It is also easier to use SSHScript module when integrating with existing projects.
+
+For example:
+```
+import sshscript
+session = sshscript.SSHScriptSession()
+session(hostname)
+print(session.stdout.strip())
+```
+This example would execute command "hostname" and print the output on stdout, too.
+To run it, please save it as "example.py", then in the console, runs:
+```
+python3 example.py
+```
+
+### The difference between SSHScript dollar-syntax and module
+
+
 Once you have added the path to your PATH environment variable, you should be able to run the sshscript command from anywhere in your terminal.
