## AI summary

Covers full and quick audits, CrUX field data, Lighthouse lab diagnostics, audit progress, history, and before-after comparisons.

- Run audits from the dashboard, Telegram, or MCP.
- Compare audits before and after fixes to verify improvement.

## Sections

### Run an audit

- Pick the site from the dashboard, /site in Telegram, or list_sites through MCP.
- Start the audit from the UI, /audit, or the run_audit MCP tool.
- A full audit pulls available Chrome field data, runs a simulated test, analyzes the result, and creates a report.
- A quick audit is useful after a fix when you want a fast comparison.

### Read the results

- nimo leads with a plain-language verdict, then shows metrics and recommendations.
- LCP describes how long visitors wait before the main content appears.
- CLS describes how much the page shifts while visitors try to read or click.
- INP describes how responsive the page feels when visitors interact.
- Diagnostics cover images, scripts, stylesheets, fonts, third parties, and page structure.
- Lighthouse scores can move between runs. nimo focuses on metric values, history, and real visitor impact.

### Compare changes

- Run an audit before and after a fix.
- nimo can compare two audits and show what improved, what got worse, and what stayed the same.
- Good prompt: Compare my last two audits. Which metrics changed enough to trust?

### Use audit history

- Audit history helps nimo tell the difference between a one-off slow run and a real trend.
- For important pages, run a manual audit before deploying a fix, then run another audit after the change ships.
