CI/CD turns "it works on my machine" into "it works, automatically, on every push" - by building, testing, and shipping each change through an automated pipeline.

CI/CD stands for continuous integration and continuous delivery (or deployment). It is the practice of automating the path from a code change to a tested, releasable - and often released - artifact.

## The problem it solves

Without automation, integrating everyone’s work is a periodic, painful event: branches drift apart, bugs surface late, and releases are manual and risky. CI/CD shrinks that loop to minutes by running the same checks on every change, so problems are caught while they are small.

## What a pipeline does

- Checks out the code for the change being tested.
- Builds it the same way every time, in a clean environment.
- Runs tests, linters, and security/quality gates.
- Produces an artifact (binary, image, package) and, for CD, deploys it.

## CI vs CD in one line

Continuous integration is about merging and verifying changes frequently and automatically. Continuous delivery extends that to keeping the software always in a releasable state; continuous deployment goes one step further and ships every passing change to production automatically.

## Why teams adopt it

The payoff is faster feedback, smaller and safer releases, less manual toil, and a build that everyone trusts. The cost is that the pipeline itself becomes infrastructure you must keep fast and reliable - which is where runners, caching, and flake management come in.
