+## Fake Ironic Python Agent
+
+FakeIPA is a tool to help test ironic scalability.
+
+FakeIPA simulate the IPA by:
+
+- Running an API server with the needed real IPA endpoint.
+- Send back fake inspection data when requested.
+- Lookup the node and save tokens.
+- Heartbeating to Ironic API with several threads looping over
+  a queue of fake agents.
+- Faking the sync/async commands needed by ironic to inspect,
+  clean and provision a node.
