README

This is a Rails project to receive webhooks from Gitlab MRs and notify people on Slack. After starting the server, visit [localhost:3000] to create a webhook target. Then, in Gitlab, create a webhook to point to the URL provided by the Rails app. The Rails app will then send a message to the Slack channel specified in the webhook target.

Currently, I am using a Tailscale Funnel to route the webhook from Gitlab to my local machine. You can set RAILS_DEVELOPMENT_HOSTS to a comma-separated list of hosts to allow webhooks from other hosts.
