+# Forge Test Suite
+
+Tests are split across parallel CI jobs defined in
+`.github/workflows/continuousIntegration.yml`.
+
+A `check-test-coverage` CI job scans the workflow file for referenced
+test directories and compares against what actually exists on disk.
+CI will fail if a test directory exists but isn't listed in any job's
+`test-dir` entry.
+
+## Adding a new test directory
+
+1. Create the directory and add your test files.
+2. Add the directory path to one of the `test-dir` matrix entries in
+   `.github/workflows/continuousIntegration.yml`.
