-# Publishing a New Version
+# Publishing new version
 
-This document outlines the process for publishing new versions of this project. We use a GitHub workflow for automated releases, but also provide manual steps for specific situations.
-
-## Automated Publishing via GitHub Workflow (Recommended)
-
-This is the preferred method for publishing new versions. It automates the entire process, including version bumping, tagging, building, and publishing.
-
-1.  **Prepare the Release:**
-
-    *   **Choose the Version Increment:** Determine the appropriate semantic versioning increment (prerelease, prepatch, preminor, premajor, patch, minor, major).
-
-    *   **Update `package.json`:** Use the `npm version` command to bump the version number. This command also supports creating pre-release versions using the `--preid pre` flag.
-
-        ```bash
-        # Example: Increment to a new patch version
-        npm version patch --no-git-tag-version
-
-        # Example: Increment to a new minor version
-        npm version minor --no-git-tag-version
-
-        # Example: Increment to a new major version
-        npm version major --no-git-tag-version
-
-        # Example: Create a pre-release (e.g., -pre.0) version
-        npm version prepatch --preid pre --no-git-tag-version
-        # OR
-        npm version preminor --preid pre --no-git-tag-version
-        # OR
-        npm version premajor --preid pre --no-git-tag-version
-
-        # Example: Increment an existing pre-release version (e.g., -pre.0 to -pre.1)
-        npm version prerelease --preid pre --no-git-tag-version
-        ```
-
-        *   `--no-git-tag-version`: This prevents `npm version` from automatically creating a git tag, as the GitHub workflow will handle this later.
-        *   `--preid pre`: Specifies that "pre" is the pre-release identifier.
-
-    *   **Update the Changelog (`CHANGELOG.md`):** Add a new section for the release. The heading *must* exactly match the format `## <VERSION>`, where `<VERSION>` is the full version number from `package.json`. Describe the changes included in the release.
-
-        ```markdown
-        ## 1.2.3
-        *   Added new feature X.
-        ```
-
-2.  **Commit and Push:** Commit the changes to `package.json`, `package-lock.json` and `CHANGELOG.md` to a the `master` branch. Create a pull request (PR) for review. If you are an administrator, you may push directly, but a PR is generally recommended for code review.
-
-3.  **Run the GitHub Workflow:** Once the PR is merged (or changes pushed directly), trigger the "Build, Test, Release" GitHub workflow. This workflow is responsible for:
-
-    *   Building the project.
-    *   Running tests.
-    *   Creating an NPM package.
-    *   Building and pushing Docker images.
-    *   Creating a GitHub Release.
-    *   Creating a Git tag for the release.
-
-## Manual Publishing (For Special Cases)
-
-Use the following steps *only* when the automated workflow is not suitable (e.g., for debugging, specific environment needs).
-
-1.  **Update Version in `package.json`:** Modify the `version` field in `package.json` to the desired version number.
-
-2.  **Create and Push Git Tag:**
-
-    ```bash
-    git tag vX.X.X  # Replace X.X.X with the version number
-    git push origin --tags
-    ```
-
-3.  **NPM Publish Options (Choose ONE):**
-
-    *   **Option A: Publish only the full `tileserver-gl` version:**
-
-        ```bash
-        npm publish --access public
-        ```
-
-    *   **Option B: Build and Publish both `tileserver-gl` and `tileserver-gl-light` using `publish.js`:**
-
-        ```bash
-        # This script builds the light version and publishes both tileserver-gl and tileserver-gl-light to NPM.
-        node publish.js
-        ```
-
-    *   **Option C: Build only the `tileserver-gl-light` version (no publish):**
-
-        ```bash
-        # This script ONLY builds the light version (e.g., for local testing or Docker image creation) without publishing.
-        node publish.js --no-publish
-        ```
-
-4.  **Build and Push Docker Images:**
-
-    ```bash
-    # Build the main image
-    docker buildx build --platform linux/amd64 -t maptiler/tileserver-gl:latest -t maptiler/tileserver-gl:X.X.X .  # Replace X.X.X
-    docker push maptiler/tileserver-gl --all-tags
-
-    # Build the light image
-    cd light
-    docker buildx build --platform linux/amd64 -t maptiler/tileserver-gl-light:latest -t maptiler/tileserver-gl-light:X.X.X .  # Replace X.X.X
-    docker push maptiler/tileserver-gl-light --all-tags
-    cd ..  # Return to the project root
-    ```
-    * Make sure you are logged into the docker registry before pushing. `docker login`
-
-**Important Considerations for Manual Publishing:**
-
-*   **Consistency:** Ensure the version number in `package.json`, the Git tag, and the Docker image tags are identical.
-*   **Credentials:** Verify that you have the necessary permissions to push Docker images and publish to NPM.
-*   **Cleanliness:** Before building Docker images, ensure your working directory is clean to avoid including unwanted files in the image.
-*   **Error Handling:** Manually publishing is more prone to errors. Double-check each step to avoid issues.
