+#### Pattern Syntax
+
+The glob implementation supports the following pattern syntax:
+
+**Basic Wildcards:**
+
+| Pattern              | Description                                                    |
+| -------------------- | -------------------------------------------------------------- |
+| `*`                  | Matches any number of characters within a single path segment. |
+| `?`                  | Matches exactly one character.                                 |
+| `[abc]`              | Matches any character in the brackets.                         |
+| `[a-z]`              | Matches any character in the range.                            |
+| `[!abc]` or `[^abc]` | Matches any character not in the brackets.                     |
+| `[!a-z]` or `[^a-z]` | Matches any character not in the range.                        |
+
+**Globstar:**
+
+| Pattern   | Description                                   |
+| --------- | --------------------------------------------- |
+| `**`      | Matches zero or more directories recursively. |
+| `**/*.js` | Matches all `.js` files in any subdirectory.  |
+
+**Brace Expansion:**
+
+| Pattern     | Description                                      |
+| ----------- | ------------------------------------------------ |
+| `{a,b,c}`   | Matches any of the comma-separated patterns.     |
+| `{1..5}`    | Matches any number in the range (1, 2, 3, 4, 5). |
+| `*.{js,ts}` | Matches files with `.js` or `.ts` extensions.    |
+
+**Extended Glob Patterns:**
+
+| Pattern      | Description                                      |
+| ------------ | ------------------------------------------------ |
+| `+(pattern)` | Matches one or more occurrences of the pattern.  |
+| `*(pattern)` | Matches zero or more occurrences of the pattern. |
+| `?(pattern)` | Matches zero or one occurrence of the pattern.   |
+| `!(pattern)` | Matches anything except the pattern.             |
+

 ```
 
+To collect all results into an array, use `Array.fromAsync`:
+
+```mjs
+const files = await Array.fromAsync(glob('src/**/*.js'));
+```
+
+**Common patterns:**
+
+| Pattern                                             | Description                                      |
+| --------------------------------------------------- | ------------------------------------------------ |
+| `glob('*.js')`                                      | All `.js` files in the current directory.        |
+| `glob('**/*.{js,ts}')`                              | All `.js` and `.ts` files recursively.           |
+| `glob('src/{components,utils}/**/*.js')`            | `.js` files in `src/components` or `src/utils`.  |
+| `glob('test/**/*.{spec,test}.js')`                  | Test files ending with `.spec.js` or `.test.js`. |
+| `glob('**/*.js', { exclude: ['node_modules/**'] })` | All `.js` files except those in `node_modules`.  |
+| `glob(['src/**/*.js', 'lib/**/*.js'])`              | `.js` files in both `src` and `lib` directories. |
+
+#### Platform Considerations
+
+* **Case sensitivity**: Glob patterns are case-insensitive on Windows and macOS,
+  case-sensitive on other platforms.
+* **Path separators**: Forward slashes (`/`) are used in patterns regardless of
+  platform; they are automatically converted to the appropriate separator.
+* **Returned paths**: Results use platform-specific path separators (`\` on Windows,
+  `/` on POSIX). Paths are relative to `options.cwd` if provided, otherwise
+  relative to the current working directory.
+* **Symlinks**: Symbolic links are followed and their targets are included in results.
+* **Hidden files**: Files starting with `.` are included in results when explicitly
+  matched, but not when using `*` or `**` patterns.
+
+[`path.matchesGlob()`][] supports the same basic glob pattern syntax for
+in-memory path matching, but does not include the `exclude` option.
