You need to use the Scheduler in order to do this, as it will enable you to perform regular updates. You need to create a GenericServer CI with the IP address where the remote repository is located. You then need to create an Independent Rule, and include within it the Palette item Run a remote script, where you will select the GenericServer CI from the Server combo, and enter the necessary git commands including git clone in the Command field. Then create a Schedule and select the Independent Rule from the Rule combo. Finally, set the rule execution frequency in the Frequency field.
