+Upload logs to Google Cloud Storage
+
+Before using this role, create at least one bucket and set up
+appropriate access controls or lifecycle events.  This role will not
+automatically create buckets (though it will configure CORS policies).
+
+This role requires the ``google-cloud-storage`` Python package to be
+installed in the Ansible environment on the Zuul executor.  It uses
+Google Cloud Application Default Credentials.
+
+**Role Variables**
+
+.. zuul:rolevar:: zuul_site_upload_logs
+   :default: true
+
+   Controls when logs are uploaded. true, the default, means always
+   upload logs. false means never upload logs. 'failure' means to only
+   upload logs when the job has failed.
+
+   .. note:: Intended to be set by admins via site-variables.
+
+.. zuul:rolevar:: zuul_log_partition
+   :default: false
+
+   If set to true, then the first component of the log path will be
+   removed from the object name and added to the bucket name, so that
+   logs for different changes are distributed across a large number of
+   buckets.
+
+.. zuul:rolevar:: zuul_log_container
+
+   This role *will not* create buckets which do not already exist.  If
+   partitioning is not enabled, this is the name of the bucket which
+   will be used.  If partitioning is enabled, then this will be used
+   as the prefix for the bucket name which will be separated from the
+   partition name by an underscore.  For example, "logs_42" would be
+   the bucket name for partition 42.
+
+   Note that you will want to set this to a value that uniquely
+   identifies your Zuul installation.
+
+.. zuul:rolevar:: zuul_log_path
+   :default: Generated by the role `set-zuul-log-path-fact`
+
+   Prepend this path to the object names when uploading.
+
+.. zuul:rolevar:: zuul_log_create_indexes
+   :default: true
+
+   Whether to create `index.html` files with directory indexes.  If set
+   to false, Swift containers can be marked with a `Web-Listings=true`
+   property to activate Swift's own directory indexing.
+
+.. zuul:rolevar:: zuul_log_path_shard_build
+   :default: false
+
+   This var is consumed by set-zuul-log-path-fact which
+   upload-logs-gcs calls into. If you set this you will get log paths
+   prefixed with the first three characters of the build uuid. This
+   will improve log file sharding.
+
+   More details can be found at
+   :zuul:rolevar:`set-zuul-log-path-fact.zuul_log_path_shard_build`.
