+## How to grant permission
+
+This plugin registers and checks ngt's permissions to plugin permission with appending `ngt-permissions.` as prefix.
+So, to grant `editRail`, please grant `ngt-permissions.editRail` in plugin permissions.
+
+In this plugin, `negative.` permissions and `fixrtm.all_permit` added by [KaizPatchX] and [fixRTM] will not work.
+Please use deny permissions and generic permission by permission management plugin.
