+# Introduction of Dataset
+
  - We release all of the text description data `text.tar.gz`; the trajectory data `data.tar.gz` with robot states, actions, DoF position, global position and global orientation informations.
- - We release the train set split `train.txt` 
+ - We release the train set split `train.txt`
+
+Here we offer a simple demo code to introduce the data formats in the dataset:
+
+``` python
+import numpy as np
+
+data = np.load("data_path"+"/xxx.npy", allow_pickle=True)
+data.item()['obs'] # [frame_nums, 71]
+data.item()['actions'] # [frame_nums, 21]
+data.item()['dof_pos'] # [frame_nums, 21]
+data.item()['root_trans'] # [frame_nums, 3]
+data.item()['root_rot'] # [frame_nums, 4]
+
+```
+
+# Dataset Statistics
+Percentage of steps for different categories of motions before and after data augmentation.

+The visualization of $x-y$ coordinates of the robot for each step in the dataset. We down-sample the data for visualization.
