# lookaside: for reading/writing simple signing signatures
# lookaside-staging: for writing simple signing signatures, preferred over lookaside

# lookaside and lookaside-staging take a value of the following:
#   lookaside:  {schema}://location
#
# For reading signatures, schema may be http, https, or file.
# For writing signatures, schema may only be file.

# The default locations are built-in, for both reading and writing:
# /var/lib/containers/sigstore for root, or
# ~/.local/share/containers/sigstore for non-root users.
