+# Coverage tooling
+
+This project uses `llvm-cov` to generate coverage reports.
+
+## 1. Key Features
+
+1. **Local or Docker Setup:**
+   You can generate coverage reports by either installing `llvm-cov` locally or using the project's Docker environment.
+
+2. **Partial Coverage Reporting:**
+   Currently, the reports are generated **without a baseline**, meaning only files touched during test execution are included.
+
+   **TODO:** Implement baseline generation to include all project files in the coverage report, even those not covered by tests.
+
+## 2. Setup
+
+To set up the required tools, follow these steps:
+
+### 2.1. Without Docker
+
+1. Update packages:
+
+```bash
+sudo apt update
+```
+
+2. Install LLVM Install the default version of LLVM:
+
+```bash
+sudo apt install llvm
+```
+
+### 2.2. Within Docker
+
+For Docker setup, refer to the [README.md](../../README.md)
+
+## How to Run
+
+To generate a coverage report, run the following command:
+
+```bash
+bazel run //tools:llvm_cov -- -t <test> -o <output_dir>
+```
+
+Replace <test> with the name of the test target and <output_dir> with the desired output directory for the report.
+
+Open the generated `index.html` file in the output directory to review test coverage.
