+## Documentation
+
+The full documentation site is built with VitePress under [`docs/`](docs/) and published to GitHub Pages. The source lives in this repository so every change rides the same review process as the libraries.
+
+- **Getting started**, **Configure & Use**, **Concepts**, **Wire formats**, **Modules**, **CLI**, **Cookbook**, and **Troubleshooting** narrative pages sit under [`docs/`](docs/).
+- The **API reference** is generated by [docfx](https://dotnet.github.io/docfx/) from the Release `net8.0` build of every shipped library. Regenerate locally with `bash docs/scripts/generate-api-ref.sh`; the same script runs in CI ahead of every VitePress build.
+- **Compliance** posture and per-version compatibility matrices sit under [`docs/compliance/`](docs/compliance/).
+
+Build the site locally:
+
+```bash
+cd docs
+npm install
+npm run build      # outputs to docs/.vitepress/dist
+npm run dev        # local dev server with hot reload
+```

 ## Overview
 MTConnect.NET is a fully featured and fully Open Source **[.NET](https://dotnet.microsoft.com/)** library for **[MTConnect](https://www.mtconnect.org/)** to develop Agents, Adapters, and Clients. Supports MTConnect versions up to 2.7. A pre-compiled Agent application is available to download as well as an Adapter application that can be easily customized.

+# MTConnect.NET Adapter
+
+[![MTConnect.NET](https://github.com/TrakHound/MTConnect.NET/actions/workflows/dotnet.yml/badge.svg)](https://github.com/TrakHound/MTConnect.NET/actions/workflows/dotnet.yml)
+
+## Overview
+This project is a ready-to-run MTConnect Adapter application. It reads data from a connected device or simulator (implemented in `DataSource.cs`) and forwards that data to an MTConnect Agent using the SHDR protocol or via MQTT, depending on which output modules are configured.
+
+The application shell is thin: `Program.cs` wires a `DataSource` instance to an `MTConnectAdapterApplication` and delegates all lifecycle management—including command-line parsing, Windows Service support, and configuration file monitoring—to the [MTConnect.NET-Applications-Adapter](../MTConnect.NET-Applications-Adapter/) library.
+
+To build your own adapter for a specific machine or controller, replace the `DataSource` class with one that reads from your hardware, then configure the output modules in `adapter.config.yaml`.
+
+## Usage
+The adapter can be run from a command-line prompt or installed as a Windows Service:
+
+```
+adapter [help|install|install-start|start|stop|remove|debug|run|run-service] [configuration_file]
+
+--------------------
+
+Options :
+
+           help  |  Prints usage information
+        install  |  Install as a Service
+  install-start  |  Install as a Service and Start the Service
+          start  |  Start the Service
+           stop  |  Stop the Service
+         remove  |  Remove the Service
+          debug  |  Runs the Adapter in the terminal (with verbose logging)
+            run  |  Runs the Adapter in the terminal
+    run-service  |  Runs the Adapter as a Service
+
+Arguments :
+--------------------
+
+  configuration_file  |  Specifies the Adapter Configuration file to load
+                         Default : adapter.config.yaml
+```
+
+#### Example 1:
+Run the adapter in the terminal
+```
+adapter run
+```
+
+#### Example 2:
+Run the adapter in the terminal with verbose (debug) logging
+```
+adapter debug
+```
+
+#### Example 3:
+Install the adapter as a Windows Service (requires Administrator privileges)
+```
+adapter install
+```
+
+#### Example 4:
+Install and immediately start the adapter as a Windows Service using a specific configuration file
+```
+adapter install-start adapter-production.yaml
+```
+
+## Configuration
+The default configuration file (`adapter.config.yaml`) is shown below:
+
+```yaml
+id: PatrickAdapter
+deviceKey: OKUMA-Lathe
+
+modules:
+
+- shdr:
+    port: 7878
+
+- mqtt:
+    server: localhost
+    port: 1883
+```
+
+* `id` - A unique identifier for this adapter instance.
+
+* `deviceKey` - The Name or UUID of the Device this adapter reports for.
+
+* `modules` - Output module configurations. Each entry specifies the protocol used to forward observations to an MTConnect Agent.
+
+For the full set of configuration properties supported by each module, see:
+- [MTConnect.NET-AdapterModule-SHDR](../Modules/MTConnect.NET-AdapterModule-SHDR/) — SHDR output module
+- [MTConnect.NET-AdapterModule-MQTT](../Modules/MTConnect.NET-AdapterModule-MQTT/) — MQTT output module
+
+## Build
+```
+dotnet publish -c:Release -f:net8.0 -r:win-x64 -p:PublishSingleFile=true --self-contained false
+```
+
+## Source Code
+This project uses the [MTConnect.NET-Applications-Adapter](../MTConnect.NET-Applications-Adapter/) library to provide the application host. Creating a custom adapter requires only implementing a `DataSource` subclass and configuring the output modules.
