 # Migrating from Klipper
 
+> [!NOTE]
+> Any add-on modules you are using will need to be reinstalled after switching to Kalico. This includes things like Beacon support, led-effect, etc.
+>
+> Any data in ~/printer_data such as printer configs and macros will be unaffected, THOUGH do back up just in case.
+
+### Option 1. Manually clone the repository
+
+If desired, make a backup copy of your existing Klipper installation by running:
+
+```bash
+mv ~/klipper ~/klipper_old
+```
+
+Then clone the Kalico repo and restart the klipper service:
+
+```bash
+git clone https://github.com/KalicoCrew/kalico.git ~/klipper
+sudo systemctl restart klipper
+```
+
+### Option 2. Using KIAUH
+
+For users that are not comfortable using Git directly, [KIAUH v6](https://github.com/dw-0/kiauh) is able to use custom repositories.
+
+To do this, add the Kalico repo to KIAUH's custom repository settings with the following steps:
+
+From the KIAUH menu select:
+
+- [S] Settings
+- 1\) Set custom Klipper repository
+- Use `https://github.com/KalicoCrew/kalico` as the new repository URL
+- Use `main` or `bleeding-edge-v2` as the new branch name
+- Select 'Y' to apply the changes
+- Enter 'B' for back twice
+- 'Q' to quit
+
+### Option 3. Adding a git-remote to the existing installation
+Can switch back to mainline klipper at any time via a `git checkout upstream_main`
+
+```bash
+cd ~/klipper
+git remote add kalico https://github.com/KalicoCrew/kalico.git
+git checkout -b upstream-main origin/master
+git branch -D master
+git checkout -b main kalico/main
+sudo systemctl restart klipper
+sudo systemctl restart moonraker
+```
