+  [meow](https://npmjs.com/package/meow) is the easiest way to write command line apps for Node.js.
 ---
 
+### Typical settings
+
 ```js
 const cli = require('meow')(`
   Usage: appname [options]
 
   Options:
-    -h, --help       show usage information
-    -v, --version    print version info and exit
+        --lang LANG    set the language
+
+  Other options:
+    -h, --help         show usage information
+    -v, --version      print version info and exit
 `, {
-  alias: { h: 'help', v: 'version', x: 'excludeTag' },
   string: ['lang'],
-  boolean: ['pager'],
-  default: { lang: 'en' },
-  '--': true,
-  stopEarly: true, /* populate _ with first non-option */
-  unknown: function () { ... } /* invoked on unknown param */
+  boolean: ['help', 'version'],
+  alias: { h: 'help', v: 'version' }
 })
+```
 
-cli.flags   // { excludeTag: true }
+`string` and `boolean` lets meow/minimist know which flags expect arguments (`string`) and which don't (`boolean`).
+
+### Using the result
+
+```js
+cli.flags   // { lang: 'en' }
 cli.input   // []
+```
 
-// yes, flags are camelCased
+Yes, flags are automatically camelCased!
+
+### Lesser-used settings
+
+```js
+meow(`...`, {
+  // Default values if flags are not specified
+  default: { lang: 'en' },
+
+  // allow using -- to stop processing flags
+  '--': true,
+
+  // Populate `_` with first non-option
+  stopEarly: true,
+
+  // Invoked on unknown param
+  unknown: function () { ... }
+})
 ```
