+### Caching even if an intermediate job fails
+
+Just like [the basic actions/cache workflow](https://github.com/actions/cache), this action has a cache restore step, and also a save step which runs after the workflow completes.
+By default, if any job in the workflow fails, the entire workflow will be stopped, and the cache will not be saved.
+
+Due to current limitations in GitHub Actions syntax, there is no built-in option for this action to save the cache even if the job fails.
+However, it does output information which you can feed into `actions/cache` yourself to achieve the same effect.
+For example, this workflow will ensure that the cache is saved if a step fails (but skipping it if the cache was hit, i.e. there's no need to cache it again).

 Caches are restored and re-saved after every run, retaining the state of the depot throughout runs.

+# Making a new release
+
+In this guide, as an example, `v2.2.0` refers to the version number of the new release that you want to make.
+
+## Part 1: Use the Git CLI to create and push the Git tags
+
+Step 1: Create a new lightweight tag of the form `vMAJOR.MINOR.PATCH`.
+
+```bash
+git clone git@github.com:julia-actions/cache.git
+cd cache
+git fetch --all --tags
+
+git checkout main
+
+git --no-pager log -1
+# Take note of the commit hash here.
+
+# Now, create a new lightweight tag of the form `vMAJOR.MINOR.PATCH`.
+#
+# Replace `commit_hash` with the commit hash that you obtained from the
+# `git log -1` step.
+#
+# Replace `v2.2.0` with the actual version number that you want to use.
+git tag v2.2.0 commit_hash
+```
+
+Step 2: Once you've created the new release, you need to update the `v2` tag to point to the new release. For example, suppose that the previous release was `v2.1.0`, and suppose that you just created the new release `v2.2.0`. You need to update the `v2` tag so that it points to `v2.2.0`. Here are the commands:
+
+```bash
+# Create/update the new v2 tag locally, where the new v2 tag will point to the
+# release that you created in the previous step.
+#
+# Make sure to change `v2.2.0` to the actual value for the tag that you just
+# created in the previous step.
+#
+# The `-f` flag forcibly overwrites the old
+# `v2` tag (if it exists).
+git tag -f v2 v2.2.0
+```
+
+Step 3: Now you need to push the tags:
+
+```bash
+# Regular-push the new `v2.2.0` tag:
+git push origin tag v2.2.0
+
+# Force-push the new v2 tag:
+git push origin tag v2 --force
+```
+
+## Part 2: Create the GitHub Release
+
+Go to the [Releases](https://github.com/julia-actions/cache/releases) section of this repo and create a new release (using the GitHub web interface).
+
+For the "choose a tag" drop-down field, select the `v2.2.0` tag that you created and pushed in Part 1 of this guide.
