+There are a bunch of online services which can help you if you are developing for Home Assistant or maintaining platforms/components. Some are directly connected to Pull Requests and the repositories itself, others are only publishing details and updates in our [gitter.im](https://gitter.im/home-assistant/home-assistant/devs) chatroom.
