+## Preparing the release
+
+This section covers changes that need to be issued as a pull request and should
+be merged before releasing the scorecard GitHub Action.
+
+### Update the scorecard-action version
+
+NOTE: we have a chicken-and-egg problem where the commit to be used for the release
+needs to have the image tag that only gets created *after* the commit is pushed. We
+workaround that by pre-selecting and referencing the image tag instead of the SHA which isn't ideal 
+but workable.
+
+Pre-select the tag which will be used for the release. For this document, we'll use: `Tag`.
+
+Update the image tag in [action.yaml](action.yaml) to use `Tag`.
+
+Example:
+
+```
+runs:
+  using: "docker"
+  image: "docker://gcr.io/openssf/scorecard-action:Tag"
+```
+
+Create a pull request with this change and merge into `main`.
