+
+## Synopsis
+
+This package is really similar to [ps-tree][gh:ps-tree] but is faster, safer and
+provides sub-children results.  
+Furthermore ps-tree is [unmaintained][gh:ps-tree-um].
+
+Uuh, and a fancy [CLI](#cli) is also available!
+
+## Usage
+
+```js
+var pidtree = require('pidtree')
+
+// Get childs of current process
+pidtree(process.pid, function (err, pids) {
+  console.log(pids)
+  // => []
+})
+
+// Include the given pid in the result array
+pidtree(process.pid, {root: true}, function (err, pids) {
+  console.log(pids)
+  // => [727]
+})
+
+// Get all the processes of the System (-1 is a special value of this package)
+pidtree(-1, function (err, pids) {
+  console.log(pids)
+  // => [530, 42, ..., 41241]
+})
+
+// Include PPID in the results
+pidtree(1, {advanced: true}, function (err, pids) {
+  console.log(pids)
+  // => [{ppid: 1, pid: 530}, {ppid: 1, pid: 42}, ..., {ppid: 1, pid: 41241}]
+})
+
+// If no callback is given it returns a promise instead
+const pids = await pidtree(1)
+console.log(pids)
+// => [141, 42, ..., 15242]
+```

+
+## CLI
+
+<img src="https://github.com/simonepri/pidtree/raw/master/media/cli.gif" alt="pidtree cli" width="300" align="right"/>
+Show a tree of the processes inside your system inside your terminal.
+
+```bash
+npx pidtree $PPID
+```
+Just replace `$PPID` with one of the pids inside your system.
+
+Or don't pass anything if you want all the pids inside your system.
+
+```bash
+npx pidtree
+```
+
+To display the output as a list, similar to the one produced from `pgrep -P $PID`,
+pass the `--list` flag.
+
+```bash
+npx pidtree --list
+```
+
+## API
+
+<a name="pidtree"></a>
+
+## pidtree(pid, [options], [callback]) ⇒ <code>[Promise.&lt;Array.&lt;Object&gt;&gt;]</code>
+Get the list of children pids of the given pid.
+
+**Kind**: global function  
+**Returns**: <code>Promise.&lt;Array.&lt;Object&gt;&gt;</code> - Only when the callback is not provided.  
+**Access**: public  
+
+| Param | Type | Default | Description |
+| --- | --- | --- | --- |
+| pid | <code>Number</code> \| <code>String</code> |  | A pid. If -1 will return all the pids. |
+| [options] | <code>Object</code> |  | Optional options object. |
+| [options.root] | <code>Boolean</code> | <code>false</code> | Include the provided pid in the list. Ignored if -1 is passed as pid. |
+| [callback] | <code>function</code> |  | Called when the list is ready. If not provided a promise is returned instead. |
