-## introduction
+## features
 
-### usage
+- **MDD-Agnostic**: Works with any valid MDD file
+- **DoIP Server**: ISO 13400-2 compliant, port configurable (default: `13400`)
+- **SOVD Mapping**: UDS ↔ SOVD REST API conversion
+- **Mock Gateway**: Built-in SOVD mock responses for testing
+- **Service Resolution**: DID → service mapping via MDD (MUX map or brute-force)
 
-### prerequisites
+## prerequisites
 
+To run the proxy you will need at least one `MDD` file. Check out [eclipse-opensovd/odx-converter](https://github.com/eclipse-opensovd/odx-converter) on how to create `MDD`(s) from ODX.
+
+Sample ODX/MDD files are available in the CDA repository: [testcontainer/odx](https://github.com/eclipse-opensovd/classic-diagnostic-adapter/tree/main/testcontainer/odx)
+
+Once you have the `MDD`(s) you can place them in `testcontainer/mdd/` or pass the path via `--mdd-dir`.
 
 ### build the executable
 
+```shell
+cargo build --release
+```
+
+### running
+
+Ensure that the config (`examples/config.toml`) fits your setup:
+
+- `doip_port` is set to the desired DoIP server port (default: `13400`)
+- `gateway_url` points to the SOVD gateway (CDA or mock)
+- `mock_gateway = true` enables built-in mock responses for testing without a real CDA
+
+Run the proxy:
+
+```shell
+cargo run --release -- --mdd-dir testcontainer/mdd
+```
+
+Or with a specific MDD file:
+
+```shell
+cargo run --release -- --mdd-file FLXC1000.mdd
+```
+
+### running with SOVD Server
+
+To use the proxy with a real SOVD Server instance, set `mock_gateway = false` in `examples/config.toml` and point `gateway_url` to the SOVD Server endpoint.
+
+## architecture
+
+```
+DoIP Client (port 13400)
+    ↓ UDS request (0x22 DID)
+Proxy (service resolution via MDD)
+    ↓ SOVD REST (GET /data/vindataidentifier_read)
+Mock Gateway OR Real SOVD Server
+    ↓ SOVD JSON response
+Proxy (MDD-based UDS encoding)
+    ↓ UDS response (0x62 DID data)
+DoIP Client
+```
+
+## directory structure
+
+- `proxy-core/`: Shared types, errors, MDD engine, and `DiagHandler` trait
+- `proxy-doip/`: DoIP transport layer (ISO 13400-2) — server and session handling
+- `proxy-sovd/`: SOVD REST client and UDS ↔ SOVD mapping
+- `proxy-main/`: Binary entry point, CLI, configuration, and example clients
+- `testcontainer/mdd/`: MDD files (FLXC1000.mdd)
+- `proxy-main/examples/`: Test clients for each MDD
+
+## configuration
+
+Edit `examples/config.toml`:
+
+- `doip_port = 13_400`: DoIP server port
+- `mock_gateway = true`: Use built-in mock responses
+- `gateway_url`: SOVD gateway endpoint
+- MDD directory: `--mdd-dir testcontainer/mdd` (default)
