+# CSE 5543 Lab 2: Interactive B- Spline Curve Editor
+
+Author: Zhe Yuan
+
+## Create Environment
+
+I use `uv` to create a virtual environment for this project. You can synchronize the environment by running:
+
+```bash
+uv sync
+```
+
+`uv` is not the only option, you can run this program in any Python environment with the required dependencies installed. The main dependencies are listed in `pyproject.toml`.
+
+## Run the Code
+To run the interactive B-Spline curve editor, execute the following command in your terminal:
+
+```bash
+uv run ibspline.py <num_points> <degree> OR <filename>
+```
+
+- `<num_points>`: An integer specifying the number of control points to create a new B-Spline curve.
+- `<degree>`: An integer specifying the degree of the B-Spline curve.
+- `<filename>`: A string specifying the path to a file containing control points to load an existing B-Spline curve.
+
+For example, to create a new B-Spline curve with 5 control points and degree 3, run:
+
+```bash
+uv run ibspline.py 5
+```
+
+To load control points from a file named `control_points.txt`, run:
+
+```bash
+uv run ibspline.py control_points.txt
+```
