+prom-authzed-proxy is a proxy for [Prometheus] that authorizes the request's [Bearer Token] with [Authzed] or [SpiceDB] and enforces a label in a PromQL query.
 
-[Authzed] is a database and service that stores, computes, and validates your application's permissions.
+[SpiceDB] is a database system for managing security-critical permissions checking.
 
-Developers create a schema that models their permissions requirements and use a client library, such as this one, to apply the schema to the database, insert data into the database, and query the data to efficiently check permissions in their applications.
+SpiceDB acts as a centralized service that stores authorization data.
+Once stored, data can be performantly queried to answer questions such as "Does this user have access to this resource?" and "What are all the resources this user has access to?".
+
+[Authzed] operates the globally available, serverless database platform for SpiceDB.
