-    This document mainly introduces the installation and deployment process of OpenClaw on Linux clients or servers. We recommend using 1Panel, an open-source Linux operation and maintenance management panel, for installation and deployment, which makes the entire process simple and fast. After OpenClaw is installed, the Feishu channel docking configuration can also be quickly completed through the 1Panel operation and maintenance management panel, facilitating the rapid implementation of a Feishu-based personal AI assistant.
