+# How Annotations Work
+
+Annotations in this context are similar to GitHub annotations or workflow commands,
+displaying a banner in the GitHub pull request.
+When the option `ANNOTATE_MISSING_LINES=True` is enabled, annotations are generated for lines missing coverage.
+To include branch coverage in these annotations, enable `BRANCH_COVERAGE=True`.
+By default, these annotations are written to the console, but you can also choose to save them elsewhere.
+
+## Storing Annotations
+
+1. **To a File**:
+   - Set the file path in `ANNOTATIONS_OUTPUT_PATH`.
+
+2. **To a Branch**:
+   - Set the branch name in `ANNOTATIONS_DATA_BRANCH`.
+   - Ensure your GitHub token has `Contents:write` permissions.
+   - Make sure the branch exists and is not protected by branch protection rules.
+   - Annotations are stored with the filename `{PR-number}-annotations.json`,
+   where `{PR-number}` is replaced by the actual PR number.
+   - Existing annotations for a PR in the branch will be overwritten if the file already exist in branch.
+   - If the GitHub token user has email privacy enabled, the email format `{id}+{login}@users.noreply.github.com` is used.
+   Where `{id}` is the user ID and `{login}` is the username.
+
+## Using the Annotations
+
+After generating the annotations, you can enable this extension.
+A URL is required where the annotations are accessible from the extension, with a placeholder for the PR number.
+For example:
+`https://raw.githubusercontent.com/PradeepTammali/python-coverage-comment/data/coverage-annotations/{PR-NUMBER}-annotations.json`
+
+The `{PR-NUMBER}` placeholder will be replaced with the actual PR number when viewing the PR diff.
