Webhooks are a way to trigger actions on a server by sending a HTTP request to a specific URL. This service listens for incoming webhooks and triggers the corresponding action.

- GitHub: If a commit is pushed to some of my GitHub repositories (those deployed on linu.sk), GitHub sends a POST request to this service, which pulls, builds and deploys the corresponding repository. This has been introduced for linuskmr/linu.sk#3.
