Building documentation for pull requests is one of the most requested features of Read the Docs. Similar to how a continuous integration system runs a test suite on every pull request, this change would build the documentation for each pull request and send build status notification to the providers’ Status API (e.g. Github Status API). This will let users check if the documentation build passed and also how the documentation looks before merging it to master.

As a student of Google Summer of Code (GSoC) 2019, I (Maksudul Haque) was tasked with building this feature. The main goal of my project was to make it possible to build documentation whenever a pull request was created, and send build status notification to the Providers’ Status API.
