+# Adding a tracker tab to your CommonClient client
+
+With the addition of ctx.make_gui() in 0.5.1 adding a UT tracker tab is very simplified,
+When you import CommonContext, try and import the UT context instead
+```py
+
+tracker_loaded = False
+try:
+    from worlds.tracker.TrackerClient import TrackerGameContext as SuperContext
+    tracker_loaded = True
+except ModuleNotFoundError:
+    from CommonClient import CommonContext as SuperContext
+```
+
+if you edit your GameManager at all, just use super().make_gui() to inheret UT's ui if it got loaded
+```py
+def make_gui(self):
+    ui = super().make_gui()
+    ui.base_title = "Minit CLIENT"
+    return ui
+```
+
+and when you start your client up add a call to ctx.run_generate() if the UT apworld was found
+```py
+if tracker_loaded:
+    ctx.run_generator()
+if gui_enabled:
+    ctx.run_gui()
+```
+
+# Calling UT's tracker engine directly
+
+This one is a bit stranger because UT is built off of client code that doesn't need a reason to run if there is no connection, but the functionality is fully there still. 
+Here's an example that instantiates the ctx object without a connection, runs generation, and then picks the correct player id from UT's internal multiworld.
+Then with the ctx created you can check which locations are in logic by:
+1. Setting ctx.missing_locations to the location IDs to be checked
+1. Filling ctx.items_received to be the NetworkItem representation of items received (Note: only the id will be checked by UT so that's why a single value tuple is valid in this example)
+1. Running updateTracker() on the ctx
+1. checking ctx.locations_available for the avaliable location IDs
+
+
+```py
+from worlds.tracker.TrackerClient import TrackerGameContext, updateTracker
+
+
+def get_tracker_ctx(name):
+    ctx = TrackerGameContext("", "", no_connection=True)
+    ctx.run_generator()
+
+    ctx.player_id = ctx.launch_multiworld.world_name_lookup[name]
+    return ctx
+
+
+def get_in_logic(ctx, items=[], locations=[]):
+    ctx.items_received = [(item,) for item in items]  # to account for the list being ids and not Items
+    ctx.missing_locations = locations
+    updateTracker(ctx)
+    return ctx.locations_available
+
+
+name = "qwintBug"
+ctx = get_tracker_ctx(name)
+print(get_in_logic(ctx, items=[16777224, 16777227, 16777289], locations=[16777360, 16777370, 16777410]))
+
+# [16777370, 16777410]
+```
