+## TODO List
+
+1. **Release Stage 1 Checkpoint**
+   - [x] `SpaTrack2`+ `MegaSAM` ➔ supports `Posed RGBD` as input. 
+   - [x] `SpaTrack2` + `Moge` ➔ supports `unposed RGB` as input.
+
+2. **Release Stage 2 Checkpoint**
+   - [ ] Track-guided Depth Stablizer.
+
+3. **Release Stage 3 Checkpoint**
+   - [ ] Sliding windows version.
+
+4. **More Releases**
+   - [ ] Some `Ceres Python Bindings` designed for SpatialTracker and Dynamic Reconstruction.
+   - [ ] More supports for other Depth Model, *i.e.*, `DepthAnything`, `StereoFoundation`, `UniDepth`, `Metric3D`.
+
+## Set up the environment
+To set up the environment for running the SpaTrack model, follow these steps:
+
+1. **Clone the Repository:**
+   ```bash
+   git clone git@github.com:henry123-boy/SpaTrack2.git
+   cd SpaTrack2
+   ```
+
+2. **Create a Virtual Environment:**
+   It's recommended to use a virtual environment to manage dependencies.
+   ```bash
+   conda create -n SpaTrack2 python=3.11
+   conda activate SpaTrack2
+   ```
+
+3. **Install Dependencies:**
+
+   Install the torch dependencies `pip` (tested with `torch2.4`).
+   ```bash
+   python -m pip install torch==2.4.1 torchvision==0.19.1 torchaudio==2.4.1 --index-url https://download.pytorch.org/whl/cu124
+   ```
+
+   Install the required Python packages using `pip`.
+   ```bash
+   python -m pip install -r requirements.txt
+   ```
+
+4. **Install SpaTrack2 Visualizer:**
+   
+   ```bash
+   cd viser
+   python -m pip install -e .
+   ```
+By following these steps, you should have a working environment ready to run the SpaTrack model.
+
+## Download the Checkpoints
+
+```
+mkdir -p checkpoints
+```
+Step1: Download the checkpoint of `Moge` from [here](https://github.com/microsoft/MoGe), and put the `model.pt` into `./checkpoints/`
+
+Step2: Download the checkpoint of `SpaTrack2` from [GoolgeDrive](https://drive.google.com/drive/folders/1GYeC639gA23N_OiytGHXTUCSYrbM0pOo?usp=sharing), and place it into `./checkpoints/`
+
+
+
+## Quick Start
+We gave two examples to illustrate the usage of `SpaTrack2`. Firstly, please download `ckpts` and `examples` via:
+```
+sh scripts/download.sh
+```   
+### Type1: Posed RGBD video *(Example0)*
+We provide an example who has Posed RGBD input with [MegaSAM](https://github.com/mega-sam/mega-sam). 
+```
+python inference.py --data_type="RGBD" --data_dir="assets/example0" --video_name="snowboard" --fps=1
+```  
+### Type2: unposed RGB video *(Example1)*
+```
+python inference.py --data_type="RGB" --data_dir="assets/example1" --video_name="xhs" --fps=6
+```
+
+### Visualize your results
+We provide two types of visualization. The guidance will be displayed in the terminal after running `inference.py`
+
+## 🌟 Recommended: Gradio Demo with SAM 🌟
+Please follow the instructions in the [app_3rd README](app_3rd/README.md) to configure the dependencies. Then, 
+```
+python -m pip install gradio==5.31.0 pako
+```
+Our gradio demo enable the user to track the points on the target object easily, just try:
+```
+python app.py
+```
+### ***Note❗***
+For users employing `vscode` as their IDE, the 3D trajectory visualization will automatically appear. Ensure that the port is accessible and consistent both locally and on the server. If not, you may need to manually forward the port using `SSH -L`.
