 ### ⚠️ Submodules have been removed from this repo in favor of environment-named tags within each sub repo instead! 
 TL;DR: Instead of checking in a new version of the submodule reference to, say, frontend, in this repo *instead* go to the sub repo (e.g. workspaces-frontend) and tag the release you wish to mark as for dev with the "dev" tag. Same with stage and prod. 
 
+### To Make A Release
+
+1. Go to https://github.com/TaskarCenterAtUW/workspaces-stack/actions/workflows/build.yaml
+2. Choose "Run Workflow"
+3. Select the environment you wish to deploy. Use the workflow in the "main" branch.
+4. Click "Run Workflow".
+5. If the workflow is deploying to stage or prod, the release may need approval. Results will be available at the page in step 1. 
+
 ### Tagging Policy
 
 For dev, tags can point to the main branch or any feature branches.
