Most pull requests arrive with a title, a branch name, and nothing else. The reviewer is left to reverse-engineer the intent from the diff, hunt through linked issues that may or may not exist, and ask follow-up questions before they can even start. That back-and-forth is a tax on everyone's time, and it is almost entirely avoidable.
A pull request template shifts the burden upstream. It prompts contributors at the moment they open a pull request to provide the context that reviewers need: what changed, why it changed, whether it breaks anything, and what issue it resolves. Done well, a template makes the review faster, the history more useful, and the project easier to contribute to.
This post covers what a pull request template is, how to set one up in a GitHub repository, and how to write one that contributors will actually fill out.
GitHub offers five certifications that validate skills across the full breadth of the platform: Foundations, Actions, Copilot, Advanced Security, and Administration. I completed each of these last year and found each one to be a genuine challenge that pushed me to revisit corners of the platform I thought I already understood.
This post walks through each certification, what it covers, how to prepare, and where to find the best study resources.
Alongside pinned comments for issues, GitHub introduced a quiet but effective change to how contributors interact with issue threads: a nudge that appears before a low-signal comment is posted, redirecting contributors toward a reaction or a subscription instead.
GitHub shipped a small but meaningful feature for issue tracking in February 2026: the ability to pin a comment to the top of any issue. It addresses a problem that every active open source project runs into sooner or later: the signal-to-noise ratio in issue threads starts degrading at exactly the moment when the thread matters most.
