+### Installing the dependencies  
+Running `pip install -r requirements.txt` should install all the necessary packages for the project.  
+
+### Generating a new key-pair  
+Running `./generate.py` should print out n, e, and d. n and e are components of the public key, while d is the private key.  
+
+### Encrypting a string  
+Running `./encrypt.py text n e` should encrypt `text` and print out the encrypted string.  
+
+### Decrypting a string  
+Running `./decrypt.py text d n` should decrypt `text` and print out the decrypted string.  
+
+### Running the CLI
+If you don't want to run the scripts separately, you can run `./main.py` to use the default CLI of the project.  
+
+### Limitations
+Due to the limited key size, the algorithm cannot correctly encrypt and decrypt strings exceeding certain lengths. To increase the length of supported strings, modify [generate.py](./generate.py) to increase the size of the generated keys.
