+### Plugin
+
+Plugin feature for the log collector is to load a user python functions at runtime by the engine and execute it.
+
+The design infrastructure allows user to extend or call their existing python scripts without needing to expose
+the implementation.  This enriches the log collection and mechanize the work flow as per user driven as per
+their requirement,
+
+### Understanding Plugin
+The plugin works like any stand-alone piece of python script or library function.
+
+The main components in plugin infrastructure are:
+
+- plugin directory
+- plugin directive in YAML
+- plugin parser in the collector engine
+
+### Plugin Directory
+Python module script are added or copied to `plugins` directory and the log engine loads these plugins during
+runtime and on demand from the YAML else they are not invoked automatically.
+
+Example:
+```
+plugins/
+├── foo_func.py
+├── ssh_execution.py
+└── telnet_execution.py
+```
+
+### Plugin Template Example
+
+plugins/foo_func.py
+```
+# Sample for documentation plugin
+
+def print_vars(var):
+    print(var)
+
+def return_vars():
+    return 1
+```
+
+You can add your own plugin modules to extend further.
+
+Test your plugin:
+```
+python3 plugins/foo_func.py
+```
+
+### YAML Syntax
+
+```
+    - plugin:
+        - plugin_name: plugin.foo_func.print_vars
+        - plugin_args:
+               - "Hello plugin"
+    - plugin:
+        -plugin_name:  return_value = plugin.foo_func.return_vars
+        - plugin_args:
+```
+
+### Plugin execution output for sample
+
+
+```
+        [PLUGIN-START]
+        Call func: plugin.foo_func.print_vars("Hello plugin")
+        Hello plugin
+        return: None
+        [PLUGIN-END]
+
+        [PLUGIN-START]
+        Call func: plugin.foo_func.return_vars()
+        return: 1
+        [PLUGIN-END]
+```
