# NuGet Package Manager Client API
#
# These API endpoints are not consumed directly by users, so there is no documentation for the
# individual endpoints. They are called by the NuGet package manager client when users run commands
# like `nuget install` or `nuget push`. The usage of the GitLab NuGet registry is documented here:
# https://docs.gitlab.com/ee/user/packages/nuget_repository/
#
# Technical debt: https://gitlab.com/gitlab-org/gitlab/issues/35798
