+    ### Demo Guidelines
+    You need to upload your image below and choose one mode of GOT, then click "Submit" to run GOT model. More characters will result in longer wait times.
+    - **plain texts OCR & format texts OCR**: The two modes are for the image-level OCR.
+    - **plain multi-crop OCR & format multi-crop OCR**: For images with more complex content, you can achieve higher-quality results with these modes.
+    - **plain fine-grained OCR & format fine-grained OCR**: In these modes, you can specify fine-grained regions on the input image for more flexible OCR. Fine-grained regions can be coordinates of the box, red color, blue color, or green color.
