About CircleCI
CircleCI is a continuous integration and delivery platform for automating software builds, tests, and deployments.
CircleCI lets development teams define pipelines as code using YAML configuration files, running automated workflows on code changes across a range of execution environments including Docker, Linux, macOS, and Windows. It is aimed at software teams that want to automate testing and release processes, with support for parallelism, caching, and orbs (reusable config packages).
Where to start
Developers typically start by adding a `.circleci/config.yml` file to their repository and connecting the repo to CircleCI through its web interface. Configuration can be written by hand using the CircleCI config reference, or generated programmatically — though note that the official JavaScript Config SDK is no longer maintained by CircleCI.
