This is my own writeup on feature flags; for a deep dive I'd recommend something like Martin Fowler's article (https://martinfowler.com/articles/feature-toggles.html).

So. Feature flags. The basic idea that you'll store configuration/values on a database/service somewhere, and by changing those values, you can change the user experience/features for a user on the fly.

Let's say that you're building a new feature, called 'new-button' which changes the color of buttons, which is currently red, to blue. Then you'd change code that looks like this -

The two files are index.php (the homepage) and search.php (the search page)

The following shell transcript shows how to:

• Create a GPG key
• Create a pass database
• Add git support to the pass database
• Create a remote git repository
• Push the pass database to the remote git repository
• Fetch and display your passwords from another host

It is assumed that the pass package has been installed on both the first and second computers.
