 ## Usage
 
-xxx
+Our ColonINST-v1 dataset consists of two parts: colonoscopy images and human-machine dialogues (in JSON format). Due to privacy concerns associated with medical images, we are unable to publicly share the original colonoscopy images. Please follow [this instruction](https://github.com/ai4colonoscopy/ColonGPT/blob/main/docs/guideline-for-ColonINST.md#dataset-access-for-coloninst) to prepare all colonoscopy images.
+
+However, the JSON files, which contain the human-machine dialogues, are available here for access. You can follow these steps:
+
+- Make sure you have the datasets library installed. You can install it via pip:
+  ```bash
+  pip install datasets
+  ```
+- You can easily download and load the dataset directly in your Python code:
+  ```bash
+  from datasets import load_dataset
+
+  # Load the ColonINST-v1 dataset
+  dataset = load_dataset("ai4colonoscopy/ColonINST-v1")
+
+  # Once downloaded, you can explore the dataset like this
+  print(dataset)
+  ```
+- If you need a specific split (e.g., train, validation, or test), you can access it like this:
+  ```bash
+  train_dataset = load_dataset("ai4colonoscopy/ColonINST-v1", split="train")
+  ```
