 In this guide, we are going to develop a [GitHub App](https://docs.github.com/en/free-pro-team@latest/developers/apps) using Go, then we deploy it as a serverless function to make use of [faasd](https://github.com/openfaas/faasd) which is a lightweight & portable faas engine. We are also going to do this demo on our local environment, so we should open our function which runs on our local environment to the Internet so Github can send events to our function. In order to do that we use inlets-pro which provides secure TCP/L4 tunnels.

 A GitHub App acts on its own behalf, taking actions via the API directly using its own identity, which means you don't need to maintain a bot or service account as a separate user.

+[Multipass](https://multipass.run) is a tool that not enough developers are using. It's 2020's answer to VirtualBox and Docker Desktop in one. You just run a few commands and get a Linux host with Ubuntu pre-installed. The best part is that it supports cloud-init scripts too.

 In order to get up and running with your own faasd installation on your Mac you can use multipass.For more details you can follow the [link](https://github.com/openfaas/faasd/blob/master/docs/MULTIPASS.md).
