 # OpenWiFi RRM Service
-OpenWiFi uCentral-based radio resource management (RRM) service, providing a
-cloud-based Wi-Fi RRM layer for APs running the OpenWiFi SDK.
+[See here](owrrm/README.md) for details.
 
-This service collects data from OpenWiFi APs (e.g. Wi-Fi scans, stats,
-capabilities) via the uCentral Gateway and Kafka, and integrates with the
-OpenWiFi Provisioning service to perform optimization across configured
-"venues". It pushes new device configuration parameters to APs after RRM
-algorithms are run (manually or periodically).
+## Project Structure
+This is an [Apache Maven] project with the following modules:
+* `lib-cloudsdk` - OpenWiFi CloudSDK Java Library
+* `owrrm` - OpenWiFi RRM Service
 
 ## Requirements
 * **Running:** JRE 11.

-## Usage
-```
-$ java -jar openwifi-rrm.jar [-h]
-```
-
-To start the service, use the `run` command while providing configuration via
-either environment variables (`--config-env`) or a static JSON file
-(`--config-file`, default `settings.json`). The following data is *required*:
-* Service configuration
-    * Env: `SERVICECONFIG_PRIVATEENDPOINT`, `SERVICECONFIG_PUBLICENDPOINT`
-    * JSON: `serviceConfig` structure
-* Kafka broker URL
-    * Env: `KAFKACONFIG_BOOTSTRAPSERVER`
-    * JSON: `kafkaConfig` structure
-* MySQL database credentials
-    * Env: `DATABASECONFIG_SERVER`, `DATABASECONFIG_USER`, `DATABASECONFIG_PASSWORD`
-    * JSON: `databaseConfig` structure
-
-## OpenAPI
-This service provides an OpenAPI HTTP interface on the port specified in the
-service configuration (`moduleConfig.apiServerParams`). An auto-generated
-OpenAPI 3.0 document is hosted at the endpoints `/openapi.{yaml,json}` and is
-written to [openapi.yaml](openapi.yaml) during the Maven "compile" phase.
-
-## For Developers
-See [IMPLEMENTATION.md](IMPLEMENTATION.md) for service architecture details and
-[ALGORITHMS.md](ALGORITHMS.md) for descriptions of the RRM algorithms.
-
+## Code Style
 Code is auto-formatted using [Spotless] with a custom Eclipse style config (see
 [spotless/eclipse-java-formatter.xml](spotless/eclipse-java-formatter.xml)).
 This can be applied via Maven (but is *not* enforced at build time):
