 ## Features
 
-### Service Cards
+### Three views
 
-Parsed per-service view showing image, ports, volumes, networks, environment, and extras (restart policy, hostname, depends_on, resource limits). Empty sections are omitted. Switch between YAML and Cards views with the tab bar.
+- **Table** *(default)* — service overview + User/Group comparison + Volume comparison, all in one place. Best for quickly spotting UID/GID mismatches or which services share which host paths.
+- **Cards** — per-service view showing image, ports, volumes, networks, environment, and extras (user, restart policy, hostname, depends_on, resource limits). Empty sections are omitted.
+- **YAML** — full sanitized YAML output, ready to paste into a gist.
 
-### Markdown Table
+### Copy as Markdown — GitHub or Discord
 
-One-click "Copy as Markdown Table" generates a table with columns for Service, Image, Ports, Volumes, and Networks — paste directly into Discord or GitHub issues.
+Two dedicated buttons:
+
+- **Copy MD (GitHub)** — `### heading` + bare pipe-table markdown. Renders as a real table on GitHub.
+- **Copy MD (Discord)** — `**bold**` labels + each table wrapped in a fenced code block. Discord doesn't render pipe tables, so the fence preserves alignment in monospace and prevents `_underscore_` / `*asterisk*` characters in volume paths from triggering inline formatting.
+
+Both formats include the Services overview, User/Group comparison, and Volume comparison sections.
+
+### User / Group merging
+
+The "User" column merges three sources of identity into a single value so you can spot mismatches at a glance:
+
+- explicit `user: <UID>:<GID>` directive
+- `PUID` / `PGID` env vars (linuxserver convention)
+- `group_add` and `UMASK` in the comparison table
+
+Lookups are case-insensitive (so a typo'd `Puid` still surfaces). When the directive matches `PUID:PGID`, only one value is shown; when they conflict, the directive is shown with the env values annotated.
 
 ### Redaction
 
 | What | Example | Result |
 |------|---------|--------|
-| Sensitive env values | `RADARR__POSTGRES__HOST: db.example.com` | `RADARR__POSTGRES__HOST: **REDACTED**` |
+| Sensitive env keys | `MYSQL_PASSWORD`, `API_KEY`, `DATABASE_URL`, `AWS_SECRET_ACCESS_KEY`, `*_FILE` variants | value replaced with `**REDACTED**` |
+| Inline credentials in URLs | `postgres://<user>:<pw>@db/app` | redacted regardless of the env-var name |
+| Vendor token formats | GitHub PATs (`ghp_…`), AWS access keys (`AKIA…`), Tailscale auth keys (`tskey-…-…`), Discord/Slack webhooks, JWTs | redacted regardless of the env-var name |
 | Email addresses | `NOTIFY: user@example.com` | `NOTIFY: **REDACTED**` |
 | Home directory paths | `/home/john/media:/tv` | `~/media:/tv` |
 
-Detected patterns: `password`, `secret`, `token`, `api_key`, `auth`, `credential`, `private_key`, `vpn_user`, and more.
-
 Safe-listed keys (kept as-is): `PUID`, `PGID`, `TZ`, `UMASK`, `LOG_LEVEL`, `WEBUI_PORT`, etc.
