+# Easy install the latest development version
+
+DeePMD-kit is actively developed in the `devel` branch. The documentation of the [`latest`](https://docs.deepmodeling.com/projects/deepmd/en/latest/) version matches the `devel` branch.
+
+The following is the way to install the pre-compiled packages without [building from source](./install-from-source.md). All of them are built with [GitHub Actions](../development/cicd.md).
+
+## Install with docker
+
+The [`devel` tag](https://github.com/deepmodeling/deepmd-kit/pkgs/container/deepmd-kit/131827568?tag=devel) is used to mark the latest development version with CUDA support:
+
+```bash
+docker pull ghcr.io/deepmodeling/deepmd-kit:devel
+```
+
+## Install with pip
+
+Below is an one-line shell command to download the [artifact](https://nightly.link/deepmodeling/deepmd-kit/workflows/build_wheel/devel/artifact.zip) containing wheels and install it with `pip`:
+
+```sh
+bash -c 'wget -O /tmp/z.$$ https://nightly.link/deepmodeling/deepmd-kit/workflows/build_wheel/devel/artifact.zip && unzip /tmp/z.$$ -d /tmp/dist.$$ && pip install -U --pre deepmd-kit[gpu,cu11,lmp] --find-links /tmp/dist.$$ && rm -r /tmp/z.$$ /tmp/dist.$$'
+```
+
+`cu11` and `lmp` are optional, which is the same as the stable version.
+
+## Download pre-compiled C Library
+
+The [pre-comiled C library](./install-from-c-library.md) can be downloaded from [here](https://nightly.link/deepmodeling/deepmd-kit/workflows/package_c/devel/libdeepmd_c.zip), or via a shell command:
+
+```sh
+wget https://nightly.link/deepmodeling/deepmd-kit/workflows/package_c/devel/libdeepmd_c.zip && unzip libdeepmd_c.zip
+```
