+
+## Add contents to your local repository
+
+  Add an entry to your animal description file, as well as an image to the `images` folder.
+
+## Commit the changes to your local repository
+
+  1. Check with status that the next commit matches what you expect.
+  2. Run the commit.
+  3. Display the log to check the commit has been added to your local history track.
+
+## Propagate the changes to your repository on GitLab
+
+  1. Push your recent commits the local repository to the remote repository.
+  2. Check your project page on GitLab to verify the push went as expected.
+
+## Shuffle contents of your local repository
+  
+  1. Rename the image file you recently added by adding  `_01` before the extension (i.e. `bumblebee.jpg` becomes `bumblebee_01.jpg`)
+  2. Add a new image file for the same animal with a filename including `_02` (i.e. `bumblebee_02.jpg`) If you can't find one you can cheat and copy the first image.
+  3. Add a file called `mistake.md` with some text contents of your choice.
+  4. Commit all your latest changes.
+  5. Check with `status` and `log` that all went as expected.
+  6. Remove the `mistake.md` file.
+  7. Commit all your latest changes.
+  8. After checking all went well, propagate the changes to the remote GitLab project.
