This explains how to automatically rebuild documentation on ReadtheDocs every time a pull request is merged into its corresponding GitHub repo.
Webhooks and services can be enabled in GitHub repo settings to allow third party services such as ReadTheDocs. The ReadTheDocs service rebuilds the project documentation whenever a pull request is merged into the GitHub repo.
Select Add service and enter ReadTheDocs in the Available Services input box.
The Services/Add ReadTheDocs window will open. Press the green Add service button to activate the ReadTheDocs service.
The ReadTheDocs service is added successfully. The service will take effect on the next merged pull request to the project repo.
