+# Updating
+
+## Using Moonraker update manager
+
+!!! info
+    This method will not work if KlipperScreen and Moonraker are on different Hosts
+
+For this to work, KlipperScreen should be added to moonraker.conf as explained in the installation instructions.
+[moonraker-configuration](Installation.md/#moonraker-configuration)
+
+Then you can update using the System panel:
+
+![system-panel-screenshot](img/panels/system.png)
+
+or from any UI that supports updating from moonraker.
+
+
+## Using KIAUH
+
+Same as in the installation instructions, but select update instead of install
+

+cd ~/KlipperScreen
+git pull
+source ~/.KlipperScreen-env/bin/activate
+pip --disable-pip-version-check install -r ~/KlipperScreen/scripts/KlipperScreen-requirements.txt
+sudo service KlipperScreen restart
