 ## Create a Virtual Environment and Install Dependencies
 
-1. The AdaSay project requires the cowsay package to run. We want to install this dependency in a virtual environment so that it is used only for this project. We first run the following command to create a virtaul environment:

 ```python -m venv venv```
 
-2. This will create a new folder named `venv` which will hold all the information about our virtual environment. Verify that this folder was created by running `ls` and seeing that `venv` is one of the folders present.
+6. This will create a new folder named `venv` which will hold all the information about our virtual environment. Verify that this folder was created by running `ls` and seeing that `venv` is one of the folders present.
 
-3. We now need to activate the virtual environment. Everything else up to this point was one-time setup, but we will need to repeat this step each time we open a new terminal to interact with this project. We activate the virtual environment by running the activation script in the `venv` folder.

 ```source venv/bin/activate```
 
-4. Verify that the virtual environment has been activated. If `(venv)` appears at the front of your shell prompt, you have successfully activated the environment.

 ```python main.py```
+
+## Make and Commit Changes
+
+11. Right now the cow doesn't say anything interesting. Let's change that! Start by opening VS Code in the AdaSay directory.
+
+```code .```
+
+12. Edit `main.py` to make the cow say something interesting. Make sure to save the file in VS Code after you make your change!
+
+13. Verify that your changes work by running `main.py` again. (Note: if you use the terminal inside VS Code, you may need to activate the virtual environment on that new terminal. See step 7.)
+
+```python main.py```
+
+14. Once you're satisfied with your changes double-check which files have been changed.
+
+```git status```
+
+15. You should expect to see that only `main.py` was changed. We'll now stage this for our commit.
+
+```git add main.py```
+
+16. Check the status of the files again. You should see that `main.py` is now shown in green, indicating that it will be part of our commit.
+
+```git status```
+
+17. Commit the changes. Add some meaningful commit message that describes the changes you made. (Hint: do not use exclamation marks in your commit message)
+
+```git commit -m "Changed cow message to COWABUNGA"```
+
+18. Push the changes to GitHub. If asked for a username and password, use your GitHub username and your Personal Access Token (PAT).
+
+```git push origin```
+
+19. Check that the changes are reflected in GitHub. Refresh the GitHub page in your browser and see that your new change is present in `main.py`.
+
+20. BONUS: do some searching online to figure out how to have cowsay use a dragon instead of a cow. Modify your code to use the dragon, stage your changes, make a commit, and push the commit to GitHub.
+
+21. Once you're finished working on this exercise, deactivate the virtual environment.
+
+```deactivate```
