 Getting admin access to CI infrastructure
 =========================================
 
-Any individual who is responsible for setting up and/or maintaining CI infrastructure for a LLVM project can
-request to be granted the CI/CD role to the LLVM organization admins. The request can be made by creating
-`a Github issue <https://github.com/llvm/llvm-project/issues/new>`_ and using the ``infrastructure`` label.
-Applicants must include a justification for why the role is being requested. Applications are reviewed on a
-case-by-case basis by the LLVM admins and the role can be revoked at any point as the LLVM admins see fit.
