-Disco ICT Plugin - Compare Active Directory user details against Disco records
\ No newline at end of file
+A plugin for [Disco ICT](https://github.com/garysharp/Disco) that compares Active Directory user details against Disco's stored records to identify mismatches.
+
+## What It Does
+
+This plugin provides:
+
+- **Full Comparison** — Iterates all Disco users and looks them up in AD, comparing core fields
+- **Mismatch Detection** — Identifies differences in Display Name, Surname, Given Name, Email, and Phone Number
+- **AD Status Checks** — Flags users not found in AD or with disabled AD accounts
+- **Web Dashboard** — In-app UI with filtering, searching, and summary stats
+- **CSV Export** — Download comparison results for reporting
+- **Detail Provider** — Stores comparison metadata as UserDetails for other plugins to consume
+- **Photo Sync** — Pulls `thumbnailPhoto` from AD for user photos
+
+## Fields Compared
+
+| Disco Field     | AD Attribute       |
+|-----------------|--------------------|
+| DisplayName     | displayName        |
+| Surname         | sn                 |

+| EmailAddress    | mail               |
