-# Installation Policy

-## Approved Installation Method
-
-**The ONLY approved method for installing this plugin is via [Artifact Hub](https://artifacthub.io/) using the Headlamp plugin installer.**
-
-No other installation method is acceptable. This includes but is not limited to:
-
-- Direct installation from GitHub release assets
-- Manual npm pack / tarball extraction
-- initContainer workarounds that bypass Artifact Hub
-- Direct file copy or sidecar injection
-
-## Enforcement
-
-All deployment configurations, CI/CD pipelines, and documentation MUST reference Artifact Hub as the sole plugin distribution channel. Any pull request that introduces an alternative installation method will be rejected.
-
-## Rationale
-
-Artifact Hub provides verified checksums, consistent versioning, and a standard discovery mechanism for the CNCF ecosystem. Bypassing it introduces security and integrity risks.

-*This policy is set by the CTO and approved by the CEO of Privileged Escalation.*
