-# Project Name
+# Noir Web Prover Circuits
 
-Brief description of what this project does and its core value proposition.
+A collection of zero-knowledge circuits written in Noir for creating Web Proofs. These circuits enable secure authentication, HTTP request verification, and JSON data extraction in zero-knowledge applications.
 
 ## Features
 
-- Key feature one with a brief explanation
-- Key feature two with a brief explanation
-- ...
+- **Encryption/Plaintext Authentication Circuit**: Verify encrypted data and authenticate plaintext without revealing sensitive information
+- **HTTP Parser and Header Locker**: Parse and lock HTTP headers in zero-knowledge proofs, ensuring request integrity
+- **JSON Parser/Extractor**: Extract and verify specific fields from JSON data within zero-knowledge proofs
+- **Constraint Counter**: Utility to analyze R1CS constraint counts for circuit optimization
 
 ## Getting Started
 
-These instructions will help you get a copy of the project up and running on your local machine.
+These instructions will help you get the circuits up and running on your local machine.
 
 ### Prerequisites
 
-What things you need to install and how to install them:
+You'll need to have Rust and Cargo installed on your system. Then, install the `just` command runner:
 
 ```bash
-npm install 
-# or ...
+cargo install just
 ```
 
 ### Installation
 
 1. Clone the repository
    ```bash
-   git clone https://github.com/username/project.git
+   git clone https://github.com/pluto/noir-web-prover-circuits.git
+   cd noir-web-prover-circuits
    ```
 
-2. Install dependencies
+2. Set up the development environment
    ```bash
-   cd project
-   npm install # or equivalent for your project
+   # This will install Noirup, Nargo, and required tools
+   just setup
    ```
 
-3. Configure environment variables
+3. Build the workspace
    ```bash
-   cp .env.example .env
-   # Edit .env with your values
+   just build
    ```
 
-4. ...
+### Available Commands
+
+- `just`: List all available commands
+- `just setup`: Set up complete development environment
+- `just build`: Build the entire Nargo workspace
+- `just test`: Run all tests
+- `just fmt`: Format code (Noir and TOML)
+- `just ci`: Run all CI checks
 
 ## Usage
 
-Show basic examples of how to use your project:
+### Using the Constraint Counter
 
-```python
-# If it's a Python project
-from project import Example
+After running `just setup` you will also get access to the `constraint_counter` utility helps analyze the R1CS constraints in your circuits:
 
-example = Example()
-result = example.do_something()
+```bash
+constraint_counter --circuit <circuit_name> --public-io-length <#_of_pub_inputs> --private-input-length <#_of_priv_inputs>
 ```
