 This repository contains the Apache DataFusion blog at https://datafusion.apache.org/blog/
 
+## Testing
+
+There are two ways to preview your blog post before publishing the site. You can
+either locally build and test the site or you can use the auto staging feature
+of the CI system. To locally build the site on your machine, follow the docker
+instructions below.
+
+To use the staging feature of the CI system, push a branch that starts with
+`site/` and create a PR to merge this branch into `main`. When you do so, it
+will trigger a CI process that will build the site and push it to the branch
+`asf-staging`. Once this completes, the ASF infrastructure will auto publish
+this staged branch to https://datafusion.staged.apache.org/
+
+The most recently run staging CI pipeline will be published to this site. If you
+need to republish any branch, simply rerun the `Stage Site` workflow.
+
 ## Setup for Docker
 
+To locally build and preview the site on your computer, you will need to build
+a docker container using these instructions:
+
 ```shell
 git clone https://github.com/apache/infrastructure-actions.git
 cd infrastructure-actions
