# AJX > Usability testing for products that agents use. Observe a fresh worker's > attempt, verify its outcome, and turn friction into evidence-backed product asks. Start with the agent quickstart when a user asks you to set up or run AJX. Install the stable CLI and matching skill together; follow the installed release's skill for execution. Real trials require usable worker and reporter authentication. The website's example data is fictional. Relative links resolve from this site's root. ## Essential - [Agent quickstart](/agents.md): Prerequisites, verified install commands, existing-skill recovery, first trial, demo, and CI. - [Website as Markdown](/index.md): Purpose, workflow, capabilities, setup prompt, and example results. - [Combined essential text](/llms-full.txt): The website and quickstart in one fetch. - [Structured content map](/site.json): Resource URLs, formats, and stable installation command. ## Evidence examples - [Example matrix](/examples/matrix.json): Fictional configurations, asks, and outcomes. - [Product asks](/examples/runs/baseline-codex-r1/asks.md): Evidence-backed changes in Markdown. - [Journey](/examples/runs/baseline-codex-r1/journey.md): Human-readable trace. - [Events](/examples/runs/baseline-codex-r1/events.jsonl): Structured fictional trace. ## Optional - [Browsable quickstart](/agents/): The same setup instructions as HTML. - [Browsable reports](/examples/): Full example reports and visual journeys. - [Canonical AJX documentation](https://github.com/royosherove/ajx): Public source, license, and detailed references. - [Canonical installation guide](https://github.com/royosherove/ajx/blob/main/docs/INSTALL.md): Release installer options and updates.
