 gd-obj allows either or both of these features. gd-obj supports uvs, faces, normals, and non triangulated meshes.
 
 ## How to use?
-Call `ObjParse.parse_file(path_to_obj, path_to_mtl)`. This will return a `Mesh` which can, for example, be placed into the `mesh` field of a `MeshInstance`.
+
+### Load from paths
+Call `ObjParse.load_obj(path_to_obj, path_to_mtl)`. This will return a `Mesh` which can, for example, be placed into the `mesh` field of a `MeshInstance`.
+
+It will try to find a mtl path if nothing entered. But you can call the function manually `ObjParse.search_mtl_path(path_to_obj)`.
+
+You can also retrieve textures path from `ObjParse.get_mtl_tex_paths(path_to_mtl)` or textures path and data from `ObjParse.get_mtl_tex(path_to_mtl)`.
+
+### Load from buffers
+Call `ObjParse.load_mtl_from_buffer(mtl_data,textures)` then call `ObjParse.load_obj_from_buffer(obj_data,materials)`.
