 Dust is an experimental project under active development. At this stage, features come and go and the API is always changing. It should not be considered for serious use yet.
 
+To get help with the shell you can use the "help" tool.
+
+```dust
+help()         # Returns a table will all tool info.
+help("random") # Returns a table with info on tools in the specified group.
+# The above is simply a shorthand for this:
+help() -> where(input, 'tool == "random"')    
+```
+
 ## Installation
 
 You must have the default rust toolchain installed and up-to-date. Install [rustup] if it is not already installed. Run `cargo install dust-lang` then run `dust` to start the interactive shell. Use `dust --help` to see the full command line options.

-**Commands** are dust's built-in tools. Some of them can reconfigure your whole system while others are do very little. They may accept different inputs, or none at all. commands in the `random` group can be run without input, but the `random_integer` command can optionally take two numbers as in inclusive range.
