 ## Release
 
-For now, releasing is done manually, by tagging a git rev with vX.Y.Z.
-
-When releasing a new version, please make sure the version is updated in the [`core/CMakeLists.txt`](https://github.com/CodSpeedHQ/codspeed-cpp/blob/main/core/CMakeLists.txt#L3) and [`core/BUILD`](https://github.com/CodSpeedHQ/codspeed-cpp/blob/main/core/BUILD#L4) files to match the pushed version
+To create a release, run `scripts/release.sh <new_version>` from the main branch. This script will:
+1. Automatically update the version in all relevant files:
+    - [`core/CMakeLists.txt`](https://github.com/CodSpeedHQ/codspeed-cpp/blob/main/core/CMakeLists.txt#L3)
+    - [`core/MODULE.bazel`](https://github.com/CodSpeedHQ/codspeed-cpp/blob/main/core/MODULE.bazel#L3)
+    - [`google_benchmark/MODULE.bazel`](https://github.com/CodSpeedHQ/codspeed-cpp/blob/main/google_benchmark/MODULE.bazel)
+2. Create a commit with the version changes
+3. Generate the CHANGELOG
+4. Tag and create the release on GitHub
