This is the 5.3 branch of the Splunk SOAR Community Playbooks repository, which contains the default initial playbooks and custom functions for each Splunk SOAR instance. Splunk SOAR was previously known as Phantom. If you are using an older version of Splunk SOAR (or Phantom) then your instance will synchronize with an older branch of this repository such as 5.2 or 4.10
The Splunk SOAR platform automatically links to the branch of this repository that matches the running Splunk SOAR version. By default this repository is named community, which can be selected as the Repo filter to only display these playbooks and custom functions. You can update your content with the Update from source control button on the playbook listing page.
