Check the starting point

Check which versions of your shell, Git, and editor are available. Back up existing configuration files. Read the collection’s README before installing it.

shell
bash --version
git --version
vim --version

Move in small pieces

Configure one tool first and test it in a new window. Review executable paths, fonts, and display settings separately: they often depend on the machine.

Leave a record of the result

Update the README with the steps you had to perform manually. A configuration you can reproduce next month is more useful than a successful setup whose details you have already forgotten.
