-* Used to create multiple stateful A1 providers (simulated near-rt-rics)
-* Supports A1-Policy and A1-EnrichmentInformation
-* Swagger-based northbound interface, so easy to change the A1 profile exposed (e.g. A1 version, A1 Policy Types, A1-E1 consumers, etc)
-* All A1-AP versions supported
+The auth-token-fetch is configured by the following environment variables.
+
+* CERT_PATH - the file path of the cert to use for TSL, example: security/tls.crt
+* CERT_KEY_PATH - the file path of the private key file for the cert, example: "security/tls.key"
+* ROOT_CA_CERTS_PATH - the file path of the trust store.
+* CREDS_GRANT_TYPE - the grant_type used for authentication, example: client_credentials
+* CREDS_CLIENT_SECRET - the secret/private shared key used for authentication
+* CREDS_CLIENT_ID - the client id used for authentication
+* OUTPUT_FILE - the path where the fetched authorization token is stored, example: "/tmp/authToken.txt"
+* AUTH_SERVICE_URL - the URL to the authentication service (Keycloak)
+* REFRESH_MARGIN_SECONDS - how long in advance before the authorization token expires it is refreshed

+RAN Performance Monitoring Functions (File-based PM)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Functions to collect/parse/filter/store/forward file-based & event-based RAN PM data:
+
+- End-to-end tool-chain to collection, parsing, filtering and delivery of file-based RAN PM observability data
+- PM report data format defined by 3GPP (TS 32.432 and 3GPP TS 32.435)
+- High performance, fully scalable
+- Subscribers (e.g. rApps) can subscribe for chosen measurement types from specific resources in the network
+
+Implementation:
+
+- Implemented in Go, Java and Python
+- Repo: *nonrtric/plt/ranpm*
+- Documentation at the :doc:`Non-RT RIC RAN PM Usecase / Functions documentation site <ranpm:index>`.
+
+Non-RT-RIC Test Framework
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A full test environment with extensive test cases/scripts can be found in the ``test`` directory in the *nonrtric* source code.
+
+Non-RT-RIC Use Cases
+~~~~~~~~~~~~~~~~~~~~
+
+"Helloworld" O-RU Fronthaul Recovery use case
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+A very simplified closed-loop rApp use case to re-establish front-haul connections between O-DUs and O-RUs if they fail. Not intended to to be 'real-world'.
