+If you do not include at least the YTAF version and enough information to determine your webOS version, your issue may be closed without a response.
+
+Check existing issues to see if there is already one covering your problem.
+
+The more information you include, the better.
+
+However, you must include *at least* the YTAF (YouTube Ad-Free) version and:
+- webOS version, or
+- firmware version (sometimes referred to as "software version" on TV) *and* either OTAID (preferred) or SoC

+

+This information can all be found in /var/run/nyx/device_info.json and /var/run/nyx/os_info.json.
+
+In `device_info.json`:
+  * SoC: `device_name`
+  * OTAID: `hardware_id`
+  * model: `product_id`
+
+In `os_info.json`:
+  * webOS version: `core_os_release`
+  * firmware version: `webos_manufacturing_version`
+
+If you do not have access to those files, the webOS version can always be found somewhere in the settings menu.
