Apply my suggestion then squash your two by two. There's no point in making WIP commits like your first and 3rd. Make sure the remaining 2 are formatted like so:

dynamic-linking.md: Fix errors

<then list your concrete changes below>

and

helloworld.md: Translate file to Markdown

<then list your concrete changes below>

Use git rebase -i HEAD~4. This will open your default editor with the list of your 4 commits. Change the word pick at the beginning of commits 2 and 4 to s (from "squash"), then save and exit. This will open your default editor again with your first 2 commit messages. Edit them as specified above, then save and exit. Then do it again for the second batch of 2 commits.
