 # Bitwise Operators in Python
 
-Source code of the least-significant bit **steganography** example from the [Bitwise Operators in Python](https://realpython.com/python-bitwise-operators/) article.  
+Source code of the least-significant bit steganography example from the [Bitwise Operators in Python](https://realpython.com/python-bitwise-operators/) tutorial.  
 
 ## Installation
 
-There are no external dependencies except for a Python interpreter.
+There are no external dependencies except for a Python interpreter. You can install this project by creating a new [virtual environment](https://realpython.com/python-virtual-environments-a-primer/), activating it, and installing the Python package:
+
+```shell
+$ python -m venv venv/
+$ source venv/bin/activate
+(venv) python -m pip install .
+```
 
 ## Running
 
-Change directory to the current folder, where this `README.md` file is located, and then execute Python module:
+Once the project is installed within your virtual environment, you can use the `stegano` command:
 
 ```shell
-$ python -m stegano /path/to/bitmap (--encode /path/to/file | --decode | --erase)
+$ stegano /path/to/bitmap (--encode /path/to/file | --decode | --erase)
 ```
 
 For example, to extract a secret file from the attached bitmap, type the following:
 
 ```shell
-$ python -m stegano example.bmp -d
+$ stegano example.bmp -d
 Extracted a secret file: podcast.mp4
 ```
