+
+> Elegant CLI Builder
+
+- Fast and lightweight argument parser based on [mri](https://github.com/lukeed/mri)
+- Smart value parsing with typecast, boolean shortcuts and unknown flag handling
+- Nested sub-commands
+- Lazy and Async commands
+- Plugable and composable API
+- Auto generated usage and help
+
+🚧 This project is under heavy development. More features are coming soon!
+
+## Usage
+
+Install package:
+
+```sh
+# npm
+npm install citty
+
+# yarn
+yarn add citty
+
+# pnpm
+pnpm install citty
+```
+
+Import:
+
+```js
+// ESM
+import { defineCommand, runMain } from "citty";
+
+// CommonJS
+const { defineCommand, runMain } = require("citty");
+```
+
+Define main command to run:
+
+```ts
+import { defineCommand, runMain } from "citty";
+
+const main = defineCommand({
+  meta: {
+    name: "hello",
+    version: "1.0.0",
+    description: "My Awesome CLI App",
+  },
+  args: {
+    name: {
+      type: "positional",
+      description: "Your name",
+      required: true,
+    },
+    friendly: {
+      type: "boolean",
+      description: "Use friendly greeting",
+    },
+  },
+  run({ args }) {
+    console.log(`${args.friendly ? "Hi" : "Greetings"} ${args.name}!`);
+  },
+});
+
+runMain(main);
+```
+
+## Utils
+
+### `defineCommand`
+
+`defineCommand` is a type helper for defining commands.
+
+### `runMain`
+
+Runs a command with usage support and graceful error handling.
+
+### `createMain`
+
+Create a wrapper around command that calls `runMain` when called.
+
+### `runCommand`
+
+Parses input args and runs command and sub-commands (unsupervised). You can access `result` key from returnd/awaited value to access command's result.
+
+### `parseArgs`
+
+Parses input arguments and applies defaults.
+
+### `renderUsage`
+
+Renders command usage to a string value.
+
+### `showUsage`
+
+Renders usage and prints to the console
+
+## Development
