 # nlc — Natural Language → Command
 
-`nlc` is a tiny command-line helper that turns natural language instructions
+`nlc` is a command-line helper that turns natural language instructions
 into executable shell commands using [OpenAI]
 (https://platform.openai.com/) models, or any model available through
 [Groq](https://groq.com/).
 
-It’s designed to be minimal and intuitive:
-
 - You type what you want in plain English.
 - It shows you the generated command inline with a `$` prompt.
 - Press **Enter** to execute, or anything else to cancel.
 
+## Usage
+
+`nlc` is built with [Bashly](https://bashly.dev) and includes utility
+subcommands. Use `nlc --help` to see top-level commands, then
+`nlc COMMAND --help` for details.
+
+At a high level:
+
+- `run` (default) turns a natural language message into a shell command.
+- `config` lets you create, edit, show, or clear the config file.
+- `prompt` lets you view or customize the system and user prompts.
