 # By default, pacman accepts packages signed by keys that its local keyring
 # trusts (see pacman-key and its man page), as well as unsigned packages.
 SigLevel    = Required DatabaseOptional
 LocalFileSigLevel = Optional
 #RemoteFileSigLevel = Required
 
 # NOTE: You must run `pacman-key --init` before first using pacman; the local
 # keyring can then be populated with the keys of all official Arch Linux
 # packagers with `pacman-key --populate archlinux`.
 
 #
 # REPOSITORIES
 #   - can be defined here or included from another file
 #   - pacman will search repositories in the order defined here
 #   - local/custom mirrors can be added here or in separate files
 #   - repositories listed first will take precedence when packages
 #     have identical names, regardless of version number
 #   - URLs will have $repo replaced by the name of the current repo
 #   - URLs will have $arch replaced by the name of the architecture
 #
 # Repository entries are of the format:
 #       [repo-name]
 #       Server = ServerName
 #       Include = IncludePath
 #
 # The header [repo-name] is crucial - it must be present and
 # uncommented to enable the repo.
 #
 
 # The testing repositories are disabled by default. To enable, uncomment the
 # repo name header and Include lines. You can add preferred servers immediately
 # after the header, and they will be used before the default mirrors.
