-`deepmd-mace` is a [MACE](https://github.com/ACEsuit/mace) plugin for [DeePMD-kit](https://github.com/deepmodeling/deepmd-kit), which connects MACE (PyTorch version) and DeePMD-kit by enabling MACE models in DeePMD-kit PyTorch backend.
+`deepmd-gnn` is a [DeePMD-kit](https://github.com/deepmodeling/deepmd-kit) plugin for various graph neural network (GNN) models, which connects DeePMD-kit and atomistic GNN packages by enabling GNN models in DeePMD-kit.
 
-After [installing the plugin](#installation), you can train the MACE model using DeePMD-kit, run active learning cycles for the MACE model using [DP-GEN](https://github.com/deepmodeling/dpgen), perform simulations with the MACE model using molecular dynamic packages supported by DeePMD-kit, such as [LAMMPS](https://github.com/lammps/lammps) and [AMBER](https://ambermd.org/).
-You can follow [DeePMD-kit documentation](https://docs.deepmodeling.com/projects/deepmd/en/latest/) to train the MACE models using its PyTorch backend, after using the specific [MACE parameters](#parameters).
+Supported packages and models include:

 ## DPRc support
 
-In `deepmd-mace`, the MACE model can be used in a [DPRc](https://docs.deepmodeling.com/projects/deepmd/en/latest/model/dprc.html) way.
+In `deepmd-gnn`, the GNN model can be used in a [DPRc](https://docs.deepmodeling.com/projects/deepmd/en/latest/model/dprc.html) way.
 Type maps that starts with `m` (such as `mH`) or `OW` or `HW` will be recognized as MM types.
 Two MM atoms will not build edges with each other.
-Such MACE+DPRc model can be directly used in AmberTools24.
