+## Cutting a new release
+
+<details>
+
+_Note: these instructions are for maintainers_
+
+1. Update the version number in [package.json](https://github.com/advanced-security/maven-dependency-submission-action/blob/main/package.json) and run `npm i` to update the lockfile. This is also a good time to make sure that the `dist/index.js` file is up to date by running `npm run build`.
+2. Go to [Draft a new
+   release](https://github.com/advanced-security/maven-dependency-submission-action/releases/new)
+   in the Releases page.
+3. Make sure that the `Publish this Action to the GitHub Marketplace`
+   checkbox is enabled

+
+4. Click "Choose a tag" and then "Create new tag", where the tag name
+   will be your version prefixed by a `v` (e.g. `v4.1.2`).
+5. Use a version number for the release title (e.g. "4.1.2").
+
+<img width="700" alt="Screenshot 2022-06-15 at 12 08 36" src="https://user-images.githubusercontent.com/2161/173822548-33ab3432-d679-4dc1-adf8-b50fdaf47de3.png">
+
+6. Add your release notes. If this is a major version make sure to
+   include a small description of the biggest changes in the new version.
+7. Build the release executables by manually triggering [this action](https://github.com/advanced-security/maven-dependency-submission-action/actions/workflows/publish_executables.yml). The output of this action will be a zip file that you should download, extract, and drag into the binaries section. There should be three files there: ending in `-linux`, `-macos`, and `-win.exe`.
+8. Click "Publish Release".
+
+You now have a tag and release using the semver version you used
+above. The last remaining thing to do is to move the dynamic version
+identifier to match the current SHA. This allows users to adopt a
+major version number (e.g. `v1`) in their workflows while
+automatically getting all the
+minor/patch updates.
+
+To do this just checkout `main`, force-create a new annotated tag, and push it:
+
+```
+git tag -fa v5 -m "Updating v5 to 5.0.0"
+git push origin v5 --force
+```

+### Configuring for Matrix-Based Workflows
 
+To ensure that the job parameter of the submission remains unique when the action is being called from a workflow that has a matrix, you can pass a `correlator` to the action. This identifier will be appended to the default correlator propterty of a job, ensuring uniqueness across matrix-based workflows. When dealing with Maven-based Java projects that utilize different `pom.xml` files across matrix jobs, you can specify the `directory` relevant to each matrix job. This ensures that the dependency snapshot accurately reflects the dependencies for each specific configuration.
+
+Example of specifying `pom.xml` files for different matrix jobs:
+
+```yaml
+jobs:
+  build:
+    runs-on: ubuntu-latest
+    strategy:
+      matrix:
+        include:
+          - java-version: 8
+            directory: project1
+          - java-version: 11
+            directory: project2
+    steps:

+    - name: Set up JDK ${{ matrix.java-version }}
+      uses: actions/setup-java@v2

+       with:
+        directory: ${{ matrix.directory }}
+        correlator: ${{ github.job }}-${{ matrix.directory }}
+```
+
+In this example, the action is configured to use different working directories based on the Java version specified in the matrix. This ensures that the dependency snapshot is accurate for each Java version being tested.
