+### `dockette/adminer:mssql`
+
+Debian-based image with Microsoft ODBC Driver 18 and PHP `sqlsrv` / `pdo_sqlsrv` extensions.
+
+```sh
+docker run \
+    --rm \
+    -p 8080:80 \
+    dockette/adminer:mssql
+```
+
+By default, `TrustServerCertificate` is set to `yes` so the image works out of the box with self-signed certificates (common in development). You can control encryption behavior via environment variables:
+
+| Variable | Description | Default |
+|---|---|---|
+| `ADMINER_PLUGIN_MSSQL_ENCRYPT` | Set to `0` to disable the encryption plugin | enabled |
+| `ADMINER_MSSQL_ENCRYPT` | `yes`, `no`, or `strict` | not set |
+| `ADMINER_MSSQL_TRUST_CERT` | `yes` or `no` | `yes` |
+
 ### `dockette/adminer:dg`
