 title="# ReNO: Enhancing One-step Text-to-Image Models through Reward-based Noise Optimization"
-description="Enter a prompt to generate an image using ReNO. Adjust the model and parameters as needed."
+description = "Enter a prompt to generate an image using ReNO. The method enhances text-to-image generation by optimizing \
+    the initial noise using reward models as detailed in the paper. The demo uses a lower learning rate (2.5) compared to the paper's default (5.0) \
+    for smoother trajectories - if you are looking for more dramatic changes, you can increase this value. You can also \
+    adjust the reward weights to e.g. prioritize either prompt following (increase ImageReward) or aesthetic quality \
+    (increase HPS/PickScore) based on your preferences.\n\nThe first time you load this demo, it will take a bit \
+    to download and initialize the required model. Once loaded, each optimization run takes about 25-60 seconds."
