+## before getting started
+
+Python 3.8 and Python 3.9 has been tested to work flawlessly. Python 3.10 will fail.
+
+### Colab
+
+Important Information: in May 2023, colab is updated to python 3.10, in order for this reproduction to work, select tools- command palatte - use fallback runtime. 
+This will change the runtime back to python 3.9.  <br>
+The fallback runtime is supported until mid May 2023, after that, we could only use other tricks to change the colab python version. <br>
+Colab TPU doesnot work here anymore, GPU runs flawlessly.
+
+
+### local machine
+
+Start with python 3.8 or python 3.9
+
+Install the following:
+
+    sudo apt-get install libilmbase-dev libopenexr-dev ffmpeg
+    
+Follow official colmap project to install with cuda support, or use default package manager to install colmap, but might only has cpu support.
+
+Then install pip requirements:
+
+    wget https://raw.githubusercontent.com/xieyizheng/hypernerf/main/requirements.txt
+    pip install -r requirements.txt
+
+With this, everything is set! The Processing, Training and Rendering notebooks should now work!
+
+## using the notebooks
+
+There are three notebooks: Processing, Training and Rendering. <br>
+- Processing turn raw video into Dataset
+- Training turn Dataset into a experiment/checkpoint
+- Rendering load a checkpoint and render desired video
+
+For our custom scenes, we can start at any notebook, just set the correct data_dir and experiment_dir at the beginning. <br>
+For rendering from a existing experiment/checkpoint, get into the config.gin and set the correct dir.
