+# App Review process
+
+We want to be as transparent as possible about the process an app goes through in order to be listed on the website. When a maintainer merges or does not merge an app on the website, it will be a result of the criteria below.
+
+These are essentially the steps we take to verify apps before listing them:
+
+- [ ] Ensure all fields in the pull request template have been checked and links are included.
+- [ ] Verify the legitimacy of each link.
+- [ ] Open each of the screenshots to ensure they show the specific app functionality as clearly as possible.
+- [ ]Install the app on a test organization
+and ensure the app works as advertised.
+- [ ] Check all links in description of app: looking mostly for relative references since folks usually copy from their readme.
+- [ ] Confirm the app slug is associated with the app.
+- [ ] Check for any written references to being a Probot/GitHub app to avoid feeling repetitive since they're on the website.
+- [ ] Think about the app's usecase and usefulness to developers. This often becomes a discussion amongst the maintainers in private channels if there's concerns that the app doesn't provide tangible benefits.
+- [ ] Read the entire description/how the app works to make sure someone new could figure it out.
+
+And if the app passes all of these checks, it will be merged in!
