+# Proxmox VE LXC
+
+{: .warning }
+> The proxmox VE LXC script for Part-DB is developed and maintained by [Proxmox VE Helper-Scripts](https://community-scripts.github.io/ProxmoxVE/)
+> and not by the Part-DB developers. Keep in mind that the script is not officially supported by the Part-DB developers.
+
+If you are using Proxmox VE you can use the scripts provided by [Proxmox VE Helper-Scripts community](https://community-scripts.github.io/ProxmoxVE/scripts?id=part-db)
+to easily install Part-DB in a LXC container.
+
+## Usage
+
+To create a new LXC container with Part-DB, you can use the following command in the Proxmox VE shell:
+
+```bash
+bash -c "$(wget -qLO - https://github.com/community-scripts/ProxmoxVE/raw/main/ct/part-db.sh)"
+```
+
+The same command can be used to update an existing Part-DB container.
+
+See the [helper script website](https://community-scripts.github.io/ProxmoxVE/scripts?id=part-db) for more information.
+
+## Bugreports
+
+If you find issues related to the proxmox VE LXC script, please open an issue in the [Proxmox VE Helper-Scripts repository](https://github.com/community-scripts/ProxmoxVE).
