+# Release Checklist
+
+These steps assume that you've checked out the `scale-info` repository and are in the root directory of it.
+
+We also assume that ongoing work done is being merged directly to the `master` branch.
+
+1.  Ensure that everything you'd like to see released is on the `master` branch.
+
+2.  Create a release branch off `master`, for example `release-v0.17.0`. Decide how far the version needs to be bumped based
+    on the changes to date.
+
+3.  Check that you're happy with the current documentation.
+
+    ```
+    cargo doc --open
+    ```
+
+    If there are minor issues with the documentation, they can be fixed in the release branch.
+
+4.  Bump the crate versions in `./Cargo.toml` and `./derive/Cargo.toml` to whatever was decided in step 2 (basically a find and
+    replace from old version to new version in this file should do the trick).
+
+5.  Update `CHANGELOG.md` to reflect the difference between this release and the last. See the `CHANGELOG.md` file for
+    details of the format it follows.
+
+    First, if there have been any significant changes, add a description of those changes to the top of the
+    changelog entry for this release.
+
+6.  Commit any of the above changes to the release branch and open a PR in GitHub with a base of `master`.
+
+7.  Once the branch has been reviewed and passes CI, merge it.
+
+8.  Now, we're ready to publish the release to crates.io.
+
+    1.  Checkout `master`, ensuring we're looking at that latest merge (`git pull`).
+
+        ```
+        git checkout master && git pull
+        ```
+
+    2.  Perform a final sanity check that everything looks ok.
+
+        ```
+        cargo test --all-targets
+        ```
+
+    3.  Run the following command to publish both crates.
+
+        ```
+        (cd derive && cargo publish) && cargo publish
+        ```
+
+9.  If the release was successful, tag the commit that we released in the `master` branch with the
+    version that we just released, for example:
+
+    ```
+    git tag -s v2.7.0 # use the version number you've just published to crates.io, not this one
+    git push --tags
+    ```
+
+    Once this is pushed, go along to [the releases page on GitHub](https://github.com/paritytech/scale-info/releases)
+    and draft a new release which points to the tag you just pushed to `master` above. Copy the changelog comments
+    for the current release into the release description.
