 # crawl-prime
 
-Crawl all prime available on http://compoasso.free.fr/primelistweb/page/prime/liste_online_en.php
+Crawl all prime numbers available on http://compoasso.free.fr/primelistweb/page/prime/liste_online_en.php
+
+*In 2025, I rewrite this project using Go. The Python version of this project can be found at [feature/python](https://github.com/tiennm99/crawl-prime/tree/feature/python) branch.*
+
+## Requirements
+
+- Go 1.18 or higher
+- Internet connection to access the prime list website
+- Write permissions in the current directory (for `primes.txt`)
 
 ## Installation

-2. Create a virtual environment:
-   ```bash
-   python -m venv venv
-   source venv/bin/activate   # On macOS/Linux
-   venv\Scripts\activate      # On Windows

+2. Install Go (if not already installed):
    ```bash
-    pip install -r requirements.txt
-    ```
+   # Download and install Go from https://golang.org/dl/
+   # Or use your package manager:
+   # Ubuntu/Debian: sudo apt install golang
+   # macOS: brew install go
+   # Windows: Download from official website
+   ```
+
+3. Install dependencies:
+   ```bash

 4. Run the script:
    ```bash
-    python main.py
-    ```
+   go run main.go
+   ```
+
+## Usage
+
+The program will automatically:
+- Start crawling from prime number 1
+- Process pages in batches of 600 primes each
+- Write all found primes to `primes.txt`
+- Display progress information during execution
+- Stop when it reaches 1,000,000 primes or encounters an error
+
+## Output
+
+- `primes.txt` - Contains all crawled prime numbers, one per line
+
+## License
