+# sd-notify
+
+> Extremely minimal wrapper around [`sd_notify`](https://www.freedesktop.org/software/systemd/man/sd_notify.html)
+
+### Usage
+
+__Example:__
+
+```javascript
+const notify = require('sd-notify')
+
+// call notify after some async start up process
+// such as in the `http` or `express` listen callback
+
+app.listen(PORT, () => {
+  console.log('listening on port ' + PORT)
+  notify()
+})
+```
+
+Calling `notify()` will inform [__systemd__](https://www.freedesktop.org/software/systemd/man/systemd.service.html) that the process has started, when using `notify` type in a service definition file, eg:
+
+```
+[Unit]
+Description=Simple notifying service
+
+[Service]
+Type=notify
+ExecStart=/usr/sbin/simple-notifying-service
+
+[Install]
+WantedBy=multi-user.target
+```
