+# Cutting a new release of the Spin Rust SDK
+
+To cut a new release, you will need to do the following:
+
+1. Confirm that [CI is green](https://github.com/fermyon/spin-rust-sdk/actions) for the commit selected to be tagged and released.
+
+2. Change the workspace version number in [Cargo.toml](./Cargo.toml) and the versions for any dependencies that are part of this workspace (e.g. `spin-macro`).
+
+3. Create a pull request with these changes and merge once approved.
+
+4. Checkout the commit with the version bump from above.
+
+5. Create and push a new tag with a `v` and then the version number.
+
+    As an example, via the `git` CLI:
+
+    ```
+    # Create a GPG-signed and annotated tag
+    git tag -s -m "Spin Rust SDK v3.1.0" v3.1.0
+
+    # Push the tag to the remote corresponding to fermyon/spin-rust-sdk (here 'origin')
+    git push origin v3.1.0
+    ```
+
+6. Pushing the tag upstream will trigger the [release action](https://github.com/fermyon/spin-rust-sdk/actions/workflows/release.yml) which publishes the crates in this workspace to `crates.io`
+
+7. If applicable, create PR(s) or coordinate [documentation](https://github.com/fermyon/developer) needs, e.g. for new features or updated functionality.
