+Tree Kill
+=========
+
+Kill all processes in the process tree, including the root process.
+
+Examples
+=======
+
+Kill all the descendent processes of the process with pid `1`, including the process with pid `1` itself:
+```js
+var kill = require('tree-kill');
+kill(1);
+```
+
+Send a signal other than SIGTERM.:
+```js
+var kill = require('tree-kill');
+kill(1, 'SIGKILL');
+```
+
+Run a callback when done killing the processes. Passes an error argument if there was an error.
+```js
+var kill = require('tree-kill');
+kill(1, 'SIGKILL', function(err) {
+    // Do things
+});
+```
+
+You can also install tree-kill globally and use it as a command:
+```sh
+tree-kill 1          # sends SIGTERM to process 1 and its descendents
+tree-kill 1 SIGTERM  # same
+tree-kill 1 SIGKILL  # sends KILL instead of TERMINATE
+```
+
+Methods
+=======
+
+## require('tree-kill')(pid, [signal], [callback]);
+
+Sends signal `signal` to all children processes of the process with pid `pid`, including `pid`. Signal defaults to `SIGTERM`.
+
+For Linux, this uses `ps -o pid --no-headers --ppid PID` to find the parent pids of `PID`.
+
+For Darwin/OSX, this uses `pgrep -P PID` to find the parent pids of `PID`.
+
+For Windows, this uses `'taskkill /pid PID /T /F'` to kill the process tree. Note that on Windows, sending the different kinds of POSIX signals is not possible.
+
+Install
+=======
+
+With [npm](https://npmjs.org) do:
+
+```
+npm install tree-kill
+```

+Changelog
+=========
+
+
+## [1.2.2] - 2019-12-11

+- security fix: sanitize `pid` parameter to fix arbitrary code execution vulnerability
+
+## [1.2.1] - 2018-11-05
+### Changed
+- added missing LICENSE file
+- updated TypeScript definitions
+
+## [1.2.0] - 2017-09-19
+### Added
+- TypeScript definitions

+- `kill(pid, callback)` works. Before you had to use `kill(pid, signal, callback)`
+
+## [1.1.0] - 2016-05-13
+### Added
+- A `tree-kill` CLI
+
+## [1.0.0] - 2015-09-17
+### Added
+- optional callback
+- Darwin support
