+### Usage
+
+- Since this space is running on a CPU, it is not possible to generate music in a reasonable time.
+- To address this, we have provided a python notebook (check Files) that handles the music generation part which can be run locally (if you have GPU) or elsewhere.
+- This uses fastAPI to accept api requests and ngrok to expose the server. The same ngrok link needs to be pasted in the input box. (Make sure to include the trailing `/`).
