+## Litcoder Solution Copy Script
+
+This script automates the retrieval and copying of submitted code from the Litcoder website to another user's account.
+
+## Requirements
+
+### Dependency Installation
+
+Before running the script, ensure you've installed the necessary dependencies using the following command:
+
+\```bash
+pip install -r requirements.txt
+\```
+
+## Dependencies
+
+The script relies on specific Python packages:
+
+- `selectolax`: An HTML parser
+- `httpx`: Enables asynchronous HTTP requests.
+
+## Running the Script
+
+### Adding Valid Credentials
+
+1. n the main.py file, input the account credentials of a user who has completed the Litcoder lab and the credentials of
+   the user to whom you intend to copy the lab code.
+
+### Executing the Script
+
+2. Run the script using the following command:
+
+\```bash
+python main.py
+\```
+
+This action will retrieve all submitted code from the provided credentials and replicate it in your account.
+
+### Output
+
+- Upon successful execution, you will find completed lab assignments in your recent lab section. You can access these
+  labs, observe the pre-written solutions, and simply submit your code afterward.
