+# LobeChat Updater
+
+This is a simple script that updates the LobeChat application. It is designed to be run on a server, and will automatically update the application when a new version is tagged.
+
+The script assumes that you use a systemd service to run LobeChat. If you do not, you will need to modify the script to suit your needs.
+
+## Installation
+
+1. Clone this repository to your server.
+    ```bash
+    git clone https://git.private.coffee/kumi/lobechat-updater.git
+    cd lobechat-updater
+    ```
+
+2. Install the `lobechat-updater` to `/usr/local/bin/`:
+    ```bash
+    sudo install lobechat-updater /usr/local/bin/
+    ```
+
+3. Install the systemd service and timer:
+    ```bash
+    sudo cp contrib/lobechat-updater.service /etc/systemd/system/
+    sudo cp contrib/lobechat-updater.timer /etc/systemd/system/
+    sudo systemctl enable --now lobechat-updater.timer
+    ```
+
+This will install the updater script to `/usr/local/bin/lobechat-updater`, and will set up a systemd timer to run the updater every 5 minutes.
+
+## Configuration
+
+Modify the `LOBECHAT_DIR` variable in `/usr/local/bin/lobechat-updater` to point to the directory where LobeChat is installed. By default, this is `/opt/lobechat`. If the user running LobeChat is not `lobechat`, you will also need to modify the `LOBECHAT_USER` variable.
+
+To change the update interval, edit the `OnBootSec` and `OnUnitActiveSec` lines in `/etc/systemd/system/lobechat-updater.timer`.
