+# Gmsh interoperability 
+This functionality is in beta stage.
+Breaking changes for this API are considered non-breaking for the package.
+Therefore, these functions are not exported yet.
+
+
+
+## API
+These methods become available via a package extension which is loaded together with 
+[Gmsh.jl](https://github.com/JuliaFEM/Gmsh.jl).
+See the general [gmsh documentation](https://gmsh.info/), the [Gmsh reference manual](https://gmsh.info/doc/texinfo/gmsh.html)
+and the [Gmsh Julia API source code](https://gitlab.onelab.info/gmsh/gmsh/blob/master/api/gmsh.jl) for  information.
