 ## Build the Sandbox
 
-This section introduces how to set up the Docker container in which the source code of Cloudberry Database v1.5.1 (released in [Cloudberry Database Release Page](https://github.com/cloudberrydb/cloudberrydb/releases)) will be compiled. In this CentOS 7.9 Docker container, a single-node cluster will be initialized with one coordinator and two segments. Both x86 and ARM CPUs (including Apple chips) are supported.
