+# Tanzu GenAI support
+
+This library is for use when accessing a Tanzu GenAI tile (version >= 10.2) configured plan with CF.  This library uses the `VCAP_SERVICES` environment data to set properties that will enable a GenAILocator.
+
+## Spring Applications
+
+Spring Applications can use this library to auto-configure a GenAILocator that can be used to determine which models/mcp servers are available, what capabilities they support and a method of accessing them.
+
+This service provides the following properties to your spring application:
+
+| Property Name            | Value                           |
+|--------------------------|---------------------------------|
+| genai.locator.config-url | config_url (from VCAP_SERVICES) |
+| genai.locator.api-base   | api_base (from VCAP_SERVICES)   |
+| genai.locator.api-key    | api_key (from VCAP_SERVICES)    |
+
+Please see the Sample Apps below for more information.
+
+### Sample Apps
+
+Sample apps using this library are available at TODO.
