+<b>Official Gradio demo</b> for <a href='https://github.com/instantX-research/CSGO' target='_blank'><b>CSGO: Content-Style Composition in Text-to-Image Generation</b></a>.<br> 
+How to use:<br>
+1. Upload a content image if you want to use image-driven style transfer.
+2. Upload a style image.
+3. Sets the type of task to perform, by default image-driven style transfer is performed. Options are <b>Image-driven style transfer, Text-driven style synthesis, and Text editing-driven style synthesis<b>. 
+4. <b>If you choose a text-driven task, enter your desired prompt<b>.  
+5. If you don't provide a prompt, the default is to use the BLIP model to generate the caption.  We suggest that by providing detailed prompts for Content images, CSGO is able to effectively guarantee content.
+6. Click the <b>Submit</b> button to begin customization.
+7. Share your stylized photo with your friends and enjoy! 😊
+
+Advanced usage:<br>
+1. Click advanced options.
+2. Choose different guidance and steps.

+📝 **Tips**
+In CSGO, the more accurate the text prompts for content images, the better the content retention.
+Text-driven style synthesis and text-edit-driven style synthesis are expected to be more stable in the next release.
