repää

Repó, short for repository, is a storage location used to hold and manage digital artifacts in software development and distribution. The term is commonly applied in two main contexts: version-control repositories and software-package repositories.

Version-control repositories store the complete history of a project, including commits, branches, tags, and the corresponding file objects. They enable collaboration by tracking changes and reconciling edits from multiple contributors. A repository can be local (on a developer’s machine) or remote (accessible over a network). Some repositories are bare, containing only history without a working checkout. Common operations include initializing a repository, cloning from a remote source, staging changes, committing, and syncing with a remote by fetching, pulling, or pushing.

Software-package repositories host compiled packages and metadata to support distribution and installation. They allow package managers to resolve dependencies, install, update, or remove software, and keep systems reproducible. Repositories are often organized as official, community, or third-party sources and are secured with cryptographic signatures. Typical workflows involve configuring sources, refreshing index files, and using package-management commands to install or upgrade packages.

Access control and governance differ by context. Version-control repositories emphasize collaboration, permissions on branches, and code review, while package repositories emphasize package integrity, signing, and controlled publishing. Repositories are central to modern software ecosystems, enabling traceability, reproducibility, and scalable distribution of both source history and software artifacts.
