+## Download the docker image
+
+Pegasus encapsulates the building environment into a [docker image](https://hub.docker.com/r/apachepegasus/build-env), you can build directly based on this environment.
+
+```sh
+docker pull apachepegasus/build-env:centos6
+```
+
+To build based on a formally released stable version (e.g {{ site.latest_pegasus_version }}), you can pull as follow:
+
+```sh
+docker pull apachepegasus/build-env:{{ site.latest_pegasus_version }}-centos6
+```
+
+## Compilation
+
+Please refer to [Downloads](/docs/downloads) to fetch the sources under a directory (`/your/local/apache-pegasus-source`). Then run the following command:
+
+```sh
+docker run -v /your/local/apache-pegasus-source:/root/pegasus \
+ apachepegasus/build-env:centos6 \
+ /bin/bash -c "./run.sh build -c"
+```
+
+The output of compilation will be placed under `DSN_ROOT` of the source directory. It includes `bin`, `include` and `lib`.
+
+## Packaging
+
+Package server binaries for deployment:
+
+```bash
+docker run -v /your/local/apache-pegasus-source:/root/pegasus \
+ apachepegasus/build-env:centos6 \
+ /bin/bash -c "./run.sh pack_server"
+```
+
+Package client libraries for C/C++ development:
+
+```bash
+docker run -v /your/local/apache-pegasus-source:/root/pegasus \
+ apachepegasus/build-env:centos6 \
+ /bin/bash -c "./run.sh pack_client"
+```
+
+Package toolset which includes various tools (shell, bench):
+
+```bash
+docker run -v /your/local/apache-pegasus-source:/root/pegasus \
+ apachepegasus/build-env:centos6 \
+ /bin/bash -c "./run.sh pack_tools"
+```
+
+If this is your first time compiling Pegasus, it's recommended to try [onebox](/overview/onebox).
