    The known commands are:

        create
	  Create database schema (needs to be executed only once)

        migrate
	  Execute database migrations (needs to be done after updates)

        rollback [VERSION]
	  Rollback database migrations (needs to be done before downgrading)

	update [OPTIONS]
	  Update the instance using the latest CI artifact for the current branch.

	  The only supported option is --no-rm, when set the script won't delete the whole directory, but
	  just force copy over files from the new release. This wastes more space, but may be useful if
	  some files are stored inside of the release directories (although you really shouldn't store them
	  there), or if you want to be able to quickly revert a broken update.

	  The script will try to detect your architecture and ABI and set a flavour automatically,
	  but if it is wrong, you can overwrite it by setting PLEROMA_CTL_FLAVOUR to the desired flavour.

	  By default the artifact will be downloaded from https://git.pleroma.social for pleroma/pleroma (project id: 2)
	  to /tmp/, you can overwrite these settings by setting PLEROMA_CTL_URI, PLEROMA_CTL_PROJECT_ID and PLEROMA_CTL_TMP_DIR
	  respectively.


    and any mix tasks under Pleroma namespace, for example \`mix pleroma.user COMMAND\` is
    equivalent to \`$(basename "$0") user COMMAND\`

    By default pleroma_ctl will try calling into a running instance to execute non migration-related commands,
    if for some reason this is undesired, set PLEROMA_CTL_RPC_DISABLED environment variable
