 ## Release
 
-To create a release, follow these steps:
-
-1. Update the version in the following locations to the new version:
-    - [`core/CMakeLists.txt`](https://github.com/CodSpeedHQ/codspeed-cpp/blob/main/core/CMakeLists.txt#L3) 
+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` module's version](https://github.com/CodSpeedHQ/codspeed-cpp/blob/main/google_benchmark/MODULE.bazel#L3)
-    - [`google_benchmark/MODULE.bazel` core dependency version](https://github.com/CodSpeedHQ/codspeed-cpp/blob/main/google_benchmark/MODULE.bazel#L6)
-2. Once the version changes are merged on main, run `scripts/release.sh <new_version>` to tag and create the release on GitHub.
+    - [`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
