 ## Usage
 
+### Element activation
+
+To activate the `element-array-ephys`, ones need to provide:
+
+1. Schema names
+    + schema name for the probe module
+    + schema name for the ephys module
+
+2. Upstream tables
+    + Session table
+    + SkullReference table (Reference table for InsertionLocation, specifying the skull reference)
+
+3. Utility functions
+    + get_ephys_root_data_dir()
+    + get_session_directory()
+
+For more detail, check the docstring of the `element-array-ephys`:
+
+    help(probe.activate)
+    help(ephys.activate)
+
+### Example usage
+
 See [this project](https://github.com/datajoint/workflow-array-ephys) for an example usage of this Array Electrophysiology Element.
