-### No ConVars and Commands
+# Description
+This plugin allows for critical hits whenever you hit the head hitbox of an enemy.
+
+# Which weapons work?
+All hitscan weapons. Projectiles DO NOT work due to how `SDKHooks_TraceAttack` works.
+
+# ConVars
+- `tf_critheadshots_enable`
+    - To enable set to 1, to disable set to 0 or any other value.
+
+# You forked a repo just for a ConVar?
+Not explicitly. If I figure out how to get minicrits to work, I will implement that as well with a cvar to switch between normal and minicrits.
