How to install jj

Jj is developer utility. The codebase is maintained by its own authors rather than by a vendor.

About the project

Jj is developer utility. The maintainers own the project, choose releases, and publish their own documentation. This page records a few things worth knowing before you begin.

The maintainers own the project. They choose release timing, publish announcements, and write the documentation themselves. Nothing about that process is controlled from here.

How releases reach a machine

Distribution depends on the project. Common routes include the system package index, a language registry, a version manager, or a source build described in the project documentation.

Platform requirements

Look at the supported versions before anything else. Projects narrow their platform range over time, and older systems can be dropped without much warning.

A quick sanity check

If the outcome differs from what you expected, the cause is nearly always resolution rather than the project itself — an older copy, a different channel, or a stale cache.

Notes on this domain

Nothing is published from this domain beyond text. Projects stay where their maintainers put them.
