+## RestServer Plugin
+In this section of you will learn how to make a `neo-cli` plugin that integrates with `RestServer`
+plugin. Lets take a look at [Example Plugin](/examples/RestServerPlugin).
+
+- No reference to `RestServer` is required.
+- Requires DotNet 7.0
+
+## Folder Structure
+```bash
+Project
+├── Controllers
+│   └── ExampleController.cs
+├── ExamplePlugin.cs
+├── ExamplePlugin.csproj
+├── Exceptions
+│   └── CustomException.cs
+└── Models
+    └── ErrorModel.cs
+```
+The only thing that is important here is the `controllers` folder. This folder is required for the `RestServer`
+plugin to register the controllers in its web server. This location is where you put all your controllers.
+
+## Controllers
+The `controller` class is the same as ASP.Net Core's. Controllers must have their attribute set
+as `[ApiController]` and inherent from `ControllerBase`.
+
+## Swagger Controller
+A `Swagger` controller uses special attributes that are set on your controller's class.
+
+**Controller Class Attributes**
+- `[Produces(MediaTypeNames.Application.Json)]` (_Required_)
+- `[Consumes(MediaTypeNames.Application.Json)]` (_Required_)
+- `[ApiExplorerSettings(GroupName = "v1")]`
+  - **GroupName** - _is which version of the API you are targeting._
+- `[ProducesResponseType(StatusCodes.Status400BadRequest, Type = typeof(ErrorModel))]` (_Required_)
+  - **Type** - _Must have a base class of [error](#error-class)._
+
+## Error Class
+Needs to be the same as `RestServer` of else there will be some inconsistencies
+with end users not knowing which type to use. This class can be `public` or `internal`.
+Properties `Code`, `Name` and `Message` values can be whatever you desire.
+
+**Model**
+```csharp
+public class ErrorModel
+{
+    public int Code { get; set; };
+    public string Name { get; set; };
+    public string Message { get; set; };
+}
+```
+
+## Controller Actions
+Controller actions need to have special attributes as well as code comments.
+
+- `[ProducesResponseType(StatusCodes.Status200OK, Type = typeof(string))]`
+
+HTTP status code `200 (OK)` is required with return type defined. You can use more than one attribute. One per HTTP status code.
+
+### Action Example
+```csharp
+[HttpGet("contracts/{hash:required}/sayHello", Name = "GetSayHello")]
+[ProducesResponseType(StatusCodes.Status204NoContent)]
+[ProducesResponseType(StatusCodes.Status200OK, Type = typeof(string))]
+public IActionResult GetSayHello(
+    [FromRoute(Name = "hash")]
+    UInt160 scripthash)
+{
+    if (scripthash == UInt160.Zero)
+        return NoContent();
+    return Ok($"Hello, {scripthash}");
+}
+```
+Notice that the _above_ example also returns with HTTP status code of `204 No Content`.
+This action `route` also extends the `contracts` API. Adding method `sayHello`. Routes
+can be what you like as well. But if you want to extend on any existing controller you
+must use existing routes paths.
+
+### Path(s)
+- `/api/v1/contracts/`
+- `/api/v1/ledger/`
+- `/api/v1/node/`
+- `/api/v1/tokens`
+- `/api/v1/Utils/`
+
+### Excluded Path(s)
+- `/api/v1/wallet/`
+
+_for security reasons_.
+
+### Code Comments for Swagger
+```csharp
+/// <summary>
+/// 
+/// </summary>
+/// <param name="" example=""></param>
+/// <returns></returns>
+/// <response code="200">Successful</response>
+/// <response code="400">An error occurred. See Response for details.</response>
+```
+
+Also note that you need to have `GenerateDocumentationFile` enabled in your
+`.csproj` file. The `xml` file that is generated; in our case would be `RestServerPlugin.xml`.
+This file gets put in same directory `Plugins/RestServerPlugin/` which is in the root of `neo-node`
+executable folder. Where you will see `neo-cli.exe`.
+
+File `RestServerPlugin.xml` will get added to `Swagger` automatically by the `RestServer`
+plugin.
