+## Mirror Mesh tool
+
+Used when you want to symmetrize a mesh across its X axis, but also wants its
+vertex weights correctly assigned after mirroring. This is different from the
+`Symmetrize` tool in stock Blender, which does not respect the symmetry of
+weight names and makes every weight group symmetric on itself.
+
+**This tool only mirrors from _Left (+X)_ to _Right (-X)_! It does not work in reverse!**
