-# Axis Sample Dataset
+# Axis Task 74 Sample Dataset
 
-This repository contains sample data for Axis Robotics.
+This repository contains sample data for **Task 74** from the Axis Robotics data collection pipeline.
 
-## Structure
+## Task Description
 
-- `raw/`: raw data
-- `smoothed/`: processed or smoothed data
+**Pick up the kettle from the left side of the table and pour its contents into the mug on the right side.**
+
+This task is a long-horizon robotic manipulation task involving object grasping, transport, pose control, and pouring behavior.
+
+## Overview
+
+This dataset is a small sample release for Task 74. It is intended to illustrate the structure of the collected trajectories and the difference between the raw data and the smoothed version used in downstream processing.
+
+The repository currently includes two folders:
+
+- `raw/`
+- `smoothed/`
+
+## Data Structure
+
+### `raw/`
+
+The `raw/` folder contains the original trajectory data directly recorded and saved from the web-based data collection interface.
+
+These files reflect the collected demonstrations in their original form before additional post-processing. They are useful for understanding the initial recorded signals and the structure of the web-collected data.
+
+### `smoothed/`
+
+The `smoothed/` folder contains the post-processed version of the same demonstrations.
+
+In this version, smoothing has been applied to:
+
+- the **3D end-effector trajectory**
+- the **robot joint trajectories**
+
+The purpose of this processing is to reduce noise and improve trajectory quality for downstream use such as replay, policy training, and analysis.
+
+## Purpose of This Sample
+
+This sample dataset is released to provide a lightweight example of the Axis Robotics data format for a real manipulation task.
+
+It can be used to:
+
+- inspect the structure of collected robot trajectories
+- compare raw and processed data
+- understand how web-collected demonstrations are refined before downstream usage
+- serve as a reference example for future larger-scale dataset releases
+
+## Notes
+
+This is a **sample dataset** for demonstration and documentation purposes. It does not represent the full Task 74 dataset.
