+For help and advice on what any of the commands does, consult the built in `cf` help functions as follows:-
+
+```bash
+cf help # List the most popular and commonly used commands
+cf help -a # Complete list of all possible commands
+cf <COMMAND_NAME> --help # Help on a specific command including arguments and examples
+```
+
+Alternatively, seek out the [online documentation][3]. And don't forget, there are loads of great [community plugins for the cf-cli][4] command line tool that can greatly extend its power and usefulness.
