-# clvm-execution-env
+Here's the updated README with the `clsp` field in place of `clvm_code`, reflecting the correct behavior of the API.
+
+---
+
+### CLVM Execution Environment
+
+This project provides a Dockerized Node.js Express server that accepts Chialisp (CLSP) code and parameters via a `POST` request, compiles the code into CLVM bytecode using Chia Dev Tools, and then runs the bytecode on the Chialisp Virtual Machine (CLVM) using `brun`.
+
+### Table of Contents
+- [Features](#features)
+- [Getting Started](#getting-started)
+- [Requirements](#requirements)
+- [Installation](#installation)
+- [Usage](#usage)
+- [API Endpoint](#api-endpoint)
+- [Environment Variables](#environment-variables)
+- [Contributing](#contributing)
+
+### Features
+- Compile Chialisp code dynamically using `run`.
+- Execute compiled Chialisp code on the CLVM using `brun`.
+- Accept input via a REST API endpoint.
+- Built with Node.js, TypeScript, and Express.
+- Containerized for easy deployment with Docker.
+
+### Getting Started
+
+These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.
+
+### Requirements
+
+- [Docker](https://www.docker.com/get-started)
+- [Node.js](https://nodejs.org/en/) (Optional for development purposes)
+
+### Installation
+
+1. **Clone the repository**:
+   ```bash
+   git clone <repository-url>
+   cd clvm-execution-env
+   ```
+
+2. **Build the Docker container**:
+   Make sure Docker is installed and running on your machine, then build the Docker image using the provided Dockerfile.
+   ```bash
+   docker build -t clvm-execution-env .
+   ```
+
+3. **Run the Docker container**:
+   Once the image is built, you can run the container using the following command:
+   ```bash
+   docker run -p 3000:3000 clvm-execution-env
+   ```
+
+   This will expose the service on port `3000` of your local machine.
+
+### Usage
+
+Once the container is running, you can make `POST` requests to the API endpoint to compile and execute Chialisp code.
+
+### API Endpoint
+
+#### `POST /run-chialisp`
+
+This endpoint accepts Chialisp (CLSP) code and parameters in the request body and returns the result of running the compiled CLVM bytecode using `brun`.
+
+- **Endpoint**: `/run-chialisp`
+- **Method**: `POST`
+- **Content-Type**: `application/json`
+
+##### Request Body Format:
+
+```json
+{
+  "clsp": "(mod (number) (defun factorial (number) (if (> number 1) (* number (factorial (- number 1))) 1)) (factorial number))",
+  "params": ["5"]
+}
+```
+
+- `clsp`: The Chialisp code (CLSP) to be compiled and run.
+- `params`: (Optional) The parameters to pass to the compiled CLVM code, formatted as an array of strings.
+
+##### Example Request:
+
+```bash
+curl -X POST http://localhost:3000/run-chialisp \
+-H "Content-Type: application/json" \
+-d '{
+  "clsp": "(mod (number) (defun factorial (number) (if (> number 1) (* number (factorial (- number 1))) 1)) (factorial number))",
+  "params": ["5"]
+}'
+```
+
+##### Example Response:
+
+```json
+{
+  "result": "120"
+}
+```
+
+### Environment Variables
+
+You can customize the behavior of the container using environment variables. The following environment variables are supported:
+
+| Variable      | Default | Description                                       |
+| ------------- | ------- | ------------------------------------------------- |
+| `PORT`        | `3000`  | The port on which the Express server will listen. |
+
+### Contributing
+
+If you wish to contribute to this project:
+
+1. Fork the repository.
+2. Create a feature branch (`git checkout -b feature/your-feature`).
+3. Commit your changes (`git commit -am 'Add some feature'`).
+4. Push to the branch (`git push origin feature/your-feature`).
+5. Open a pull request.
+
+Feel free to open issues to report bugs or request features.
+
+### License
+
+This project is licensed under the MIT License. See the `LICENSE` file for details.

+
+Now, the `clsp` field correctly indicates that the API accepts and runs Chialisp code. Let me know if you need any other changes or additions!
