 2. Put the `.jsx` and `.py` file into your After Effects' ScriptUI Panels folder (`Support Files/Scripts/ScriptUI Panels/`).
 3. Launch After Effects and access the script panel from the `Window` menu.
 
+When importing a REAPER project file, the script will read tracks prefixed with `!`, and return a JSON object of the timecodes for the start of each item *and* MIDI note for each respective track. After selecting a track and hitting the `Go!` button, comp markers will be added to the current comp for each item of the selected track.
+
+The markers added to the comp can be used in conjunction with expressions to determine when a video should be flipped, restart, animated, etc.
+
+A brief example of using this script with the expressions from [my expressions library](https://github.com/stysmmaker/mmkr):
+```js
+// Apply to time remap
+const { YTPMV } = footage('mmkr.jsx').sourceData.get_functions();
+YTPMV.time_reset(thisComp.marker);
+```
+```js
+// Apply to an instance of the Transform effect
+const { YTPMV } = footage('mmkr.jsx').sourceData.get_functions();
+YTPMV.flip(thisComp.marker);
+```
+
 ## Roadmap
 
 Currently this is essentially just a dump of the script files I use currently, eventually I'd like to clean them up and add a few more features.
