+# Native Image Layer Tests
+
+The Native Image Layer tests represent a way of automatically testing the Native Image Layer feature with the newest JDKs and the most popular Maven libraries, on a weekly schedule. The tests are run as a weekly GitHub action, defined in [ni-layers.yml](/.github/workflows/ni-layers.yml). 
+
+These tests work by running layer-building jobs for each library in [popular-maven-libraries.json](popular-maven-libraries.json), which is automatically generated (Vojin Jovanovic) and updated periodically. The libraries that fail to build are added to [excluded-popular-maven-libraries.json](excluded-popular-maven-libraries.json) and are excluded from future buildings until their issues are fixed.
