+OpsLevel is an internal developer portal that helps engineering teams to build, manage, and operate their services with confidence.
+It provides a single source of truth for all their services, making it easy to discover, understand, and manage them.
+
+The main components of OpsLevel include:
+- **Catalog**: A comprehensive catalog of components, services and infrastructure, including metadata, ownership, and documentation. This can be broken down further into:
+    - Teams
+    - Components (previously known as services. This is the main entity in OpsLevel, representing a service or application that is owned by a team. Has a name, description and type)
+    - Repositories
+    - Infrastructure
+    - Systems (a way to represent Components that combine to form a unified whole or function.)
+    - Domains (large business units or verticals, made up of Systems)
+    - Component Dependencies
+- **Component Maturity**: A set of customer defined best practices and standards for building and operating services, including security, reliability, and performance.
+    - Rubrics (evaluation of these determines a component's maturity level across an organization)
+    - Scorecards (like a rubric but does not impact maturity level)
+    - Checks (scorecards and rubrics are made up of individual checks like "has a README" or "has a health check")
+    - Filters (a named set of predicates that select components based on their metadata, like "uses rails" or "is owned by team X")
+- **Actions**: Tools and integrations that help automate common tasks and workflows, such as deployment, monitoring, and incident response.
