⚠️ Potential issue | 🟡 Minor | ⚡ Quick win

Fix markdown formatting for the table of contents.

The topics list is concatenated into a single line without proper line breaks, making it difficult to read. Each topic should be on a separate line.

## Migration steps

1. Read this guide and compare your custom values against `charts/matcher/values.yaml`.
2. Add any required new values for your environment, especially secrets, configmaps, probes, ingress, and service settings.
3. Render the chart locally with your production values and review the manifest diff.
4. Apply the upgrade in a controlled environment before production.

⚠️ Potential issue | 🟠 Major | ⚡ Quick win

Resolve inconsistency between migration steps and stated changes.

Step 2 instructs users to "Add any required new values for your environment, especially secrets, configmaps, probes, ingress, and service settings," but the Configuration changes section explicitly states "No direct values.yaml key changes detected" (lines 21, 25) and "No image, env, secret, probe, ingress, service, port, or enablement changes detected" (line 29).

This contradictory guidance will confuse users about whether they need to add new values or not.

📋 Proposed fix to align migration steps with actual changes
 ## Migration steps

-2. Add any required new values for your environment, especially secrets, configmaps, probes, ingress, and service settings.
