+# Performance tests
+
+## Running
+
+Each subdirectory contains a network.yaml and simulation.yaml defining a keramik test that is designed to be run through the Github Action [run-performance](./.github/workflows/run-performance.yaml).
+
+The test name is the directory name.
+
+To run a test, go to the ["Run Performance" Github Action](https://github.com/3box/ceramic-tests/actions/workflows/run-performance.yaml) and use the directory name for the "Folder name containing the performance test yaml" input.
+
+## Adding a new test
+
+To add a new test, create a new directory with a network.yaml and simulation.yaml.
+
+Ensure that the following setting are used to capture metrics.
+
+```
+spec:
+  monitoring:
+    namespaced: true
+    podMonitor:
+      enabled: true
+```
