+# dash.js Release Procedure
+
+## Pre-release: (Post Code Freeze Date)
+* Update version numbers in `package.json`
+* Create a new release candidate for all changes pulled into the `development` branch (even if they are minor).
+* The release candidate should be a branch named RC_vX.X.X not a tag.
+* Create Release Notes and share on Google Groups mailing list for feedback.
+
+## Release
+* Merge the `development` branch into the `master` branch. `development` should be the same exact state as the Latest RC Branch.
+* Once the changes are merged into the `master` branch pull the `master` branch locally and build `dist` files by running `npm run build`.
+* Push the resulting `dist` files to the `master` branch.
+* Use the Git Release UI to draft a release.
+    * Tag the release with the version number, e.g. `vx.x.x`
+    * Title the release `dash.js vX.X.X`
+    * Add the release notes created beforehand.
+    * Save as a draft for now.
+* Update and upload the archive index page for the player.
+* Publish the Git release by going to saved draft and clicking publish.
