+<b>Official 🤗 Gradio demo</b> for <a href='https://github.com/InstantID/InstantID' target='_blank'><b>InstantID: Zero-shot Identity-Preserving Generation in Seconds</b></a>.<br>
+
+How to use:<br>
+1. Upload a person image or cropped face image. For multiple person images, we will only detect the biggest face. Make sure face is in good condition and not significantly blocked or blurred.
+2. (Optionally) upload another person image as reference pose. If not uploaded, we will use the first person image to extract landmarks. 
+3. Enter a text prompt as normal text-to-image model.
+4. Click the <b>Submit</b> button to start customizing.
+5. Share your customizd photo with your friends, enjoy😊!

+### Usage tips of InstantID
+1. If you're not satisfied with the similarity, scroll down to "Advanced Options" and increase the weight of "IdentityNet Strength" and "Adapter Strength".
+2. If you feel that the saturation is too high, first decrease the Adapter strength. If it is still too high, then decrease the IdentityNet strength.
+3. If you find that text control is not as expected, decrease Adapter strength.
