Repository lifecycle
Clone, inspect remotes, create a branch, commit focused changes, push and open a pull request.
DevOps module 01
Git and GitHub without guesswork.
Understand the workflow that protects production: branch, review, validate, merge, release and recover.
Branching strategy
Use short-lived branches, protected main, mandatory reviews and automated checks before merge.
Commit quality
Write small, reversible commits with meaningful messages and avoid mixing unrelated changes.
Pull-request flow
Explain intent, risk, testing evidence, rollback and deployment impact before approval.
Release control
Tag immutable releases, generate notes and keep production deployment traceable to a commit.
Recovery
Use revert for shared history, reset only for local history and resolve conflicts deliberately.
Practice outcome
Complete one pull request with a clear description, successful checks, reviewer feedback and a documented rollback path.
