+Do you prepare to read a long article before clicking the tutorial? Since we can teach you how to setup a DeePMD-kit training in 5 minutes, we can also teach you how to install DeePMD-kit in 5 minutes. The installation manual will be introduced as follows:
+
+## Install with conda
+
+After you install `conda`, you can install the CPU version with the following command:
+
+```sh
+conda install deepmd-kit=*=*cpu lammps-dp=*=*cpu -c deepmodeling
+```
+
+To install the GPU version containing CUDA 10.1:
+
+```sh
+conda install deepmd-kit=*=*gpu lammps-dp=*=*gpu -c deepmodeling
+```
+
+If you want to use the specific version, just replace `*` with the version:
+
+```sh
+conda install deepmd-kit=1.3.3=*cpu lammps-dp=1.3.3=*cpu -c deepmodeling
+```
+
+## Install with offline packages
+
+Download offline packages in the [Releases page](https://github.com/deepmodeling/deepmd-kit/releases), or use `wget`:
+
+```sh
+wget https://github.com/deepmodeling/deepmd-kit/releases/download/v1.3.3/deepmd-kit-1.3.3-cuda10.1_gpu-Linux-x86_64.sh -O deepmd-kit-1.3.3-cuda10.1_gpu-Linux-x86_64.sh
+```
+
+Take an example of `v1.3.3`. Execuate the following commands and just follow the prompts.
+
+```sh
+sh deepmd-kit-1.3.1-cuda10.1_gpu-Linux-x86_64.sh
+```
+
+## With Docker
+
+To pull the CPU version:
+
+docker pull ghcr.io/deepmodeling/deepmd-kit:1.2.2_cpu
+To pull the GPU version:
+
+docker pull ghcr.io/deepmodeling/deepmd-kit:1.2.2_cuda10.1_gpu
+
+## Tips
+
+`dp` is the program of DeePMD-kit and `lmp` is the program of LAMMPS.
+
+```sh
+dp -h
+lmp -h
+```
+
+GPU version has contained CUDA Toolkit. Note that different CUDA versions support different NVIDIA driver versions. See [NVIDIA documents](https://docs.nvidia.com/deploy/cuda-compatibility/) for details.
+
+Don't hurry up and try such a convenient installation process. But I still want to remind everyone that the above installation methods only support the official version released by DeePMD-kit. If you need to use the devel version, you still need to go through a long compilation process. Please refer to the [installation manual](https://docs.deepmodeling.org/projects/deepmd/).
