 ## Dependent Services
 
 This image includes [wait-for-it.sh](https://github.com/vishnubob/wait-for-it) which can be useful if you need to wait for a dependent web service to start accepting requests before your Puppeteer container attempts connecting to it. See [the example](example) for usage.
+
+## Releasing
+
+1. Create a new release on GitHub. The image is tagged with the same version as Puppeteer.
+2. Docker Hub automatically builds images for the tag.
+3. There is no step 3.
