+# LiveTime Companion Module
+
+This module controls the [LiveTime](https://www.workflownetwork.com/products/live-time) software using the [beta API](https://workflownetwork.zendesk.com/hc/en-us/articles/4421381933079) that was added in verison 1.18.
+
+## Requirements
+
+- Must be on server version 1.18 or higher
+- Must have a server on and the Presets Engine module enabled (via an In-App Purchase).
+- Presets called by the API must exist on the same Mac that the Server is on. If using a Preset built on another LiveTime Mac, please use the export/import Preset functions.
+- The server password must be enabled.
+- API must be turned on in Live Time preferences.
+
+## Known issues
+
+- There currently isn't a way to set a timer without also starting it (API Limitation)
+- The "Reset" action's auto-start option isn't working correctly (API Bug?)
+  - For now, keep that option disabled.
+- Time-of-Day is slow to show up when called (API Bug?)
+
+_(I'm calling those last 2 API bugs because they exhibit the same behaviour when the request is sent from CURL, so it isn't a Companion issue)_
+

+  - Start
+  - Stop
+  - Set
+  - Reset
+- Presets
