 1. Implement a request body structure that conforms to the `Encodable` protocol. (Optional)
 
-```swift
-struct RegisterUserRequestBody: Encodable {
-    let name: String
-    let description: String
-}
-```
+    ```swift
+    struct RegisterUserRequestBody: Encodable {
+        let name: String
+        let description: String
+    }
+    ```
 
 2. Implement a response body structure that conforms to the `Decodable` protocol.
 
-```swift
-struct RegisterUserResponseBody: Decodable {
-    let id: String
-}
-
-extension RegisterUserResponseBody {
-    func convertToUserID() -> UserID { .init(id: self.id) }
-}
-```
+    ```swift
+    struct RegisterUserResponseBody: Decodable {
+        let id: String
+    }
+    
+    extension RegisterUserResponseBody {
+        func convertToUserID() -> UserID { .init(id: self.id) }
+    }
+    ```
 
 3. Implement a request structure that conforms to the `Request` protocol.
 
-```swift
-import HTTPClient
-
-struct RegisterUserRequest: Request {
-    typealias ResponseBody = RegisterUserResponseBody
-    var path: String { "user/create_user" }
-    var httpMethod: HTTPMethod { .post }
-    var httpHeaders: [HTTPHeaderField: String]? { [.contentType: ContentType.applicationJson.rawValue] }
-}
-```
+    ```swift
+    import HTTPClient
+    
+    struct RegisterUserRequest: Request {
+        typealias ResponseBody = RegisterUserResponseBody
+        var path: String { "user/create_user" }
+        var httpMethod: HTTPMethod { .post }
+        var httpHeaders: [HTTPHeaderField: String]? { [.contentType: ContentType.applicationJson.rawValue] }
+    }
+    ```
 
 4. Create an instance of the `HTTPClient` class and call the `request` method.
 
-```swift
-struct UserID: Identifiable, Equatable {
-    let id: String
-}
-```
-
-```swift
-protocol VersatileRepository {
-    func registerUser(name: String, description: String, completion: @escaping (Result<UserID, Error>) -> Void)
-}
-```
+    ```swift
+    struct UserID: Identifiable, Equatable {
+        let id: String
+    }
+    ```
 
-```swift
-import HTTPClient
+    ```swift
+    protocol VersatileRepository {
+        func registerUser(name: String, description: String, completion: @escaping (Result<UserID, Error>) -> Void)
+    }
+    ```
 
-final class VersatileAPIClient {
-    static let shared = VersatileAPIClient()
+    ```swift
+    import HTTPClient
 
-    private let httpClient = HTTPClient(baseURLString: "https://example.com/api/")
-}
-
-extension VersatileAPIClient: VersatileRepository {
-    func registerUser(name: String, description: String, completion: @escaping (Result<UserID, Error>) -> Void) {
-        let requestBody = RegisterUserRequestBody(name: name, description: description)
-        httpClient.request(RegisterUserRequest(), requestBody: requestBody) { result in
-            switch result {
-            case let .success(responseBody):
-                completion(.success(responseBody.convertToUserID()))
-            case let .failure(error):
-                completion(.failure(error))
+    final class VersatileAPIClient {

+    }

+    extension VersatileAPIClient: VersatileRepository {
+        func registerUser(name: String, description: String, completion: @escaping (Result<UserID, Error>) -> Void) {
+            let requestBody = RegisterUserRequestBody(name: name, description: description)
+            httpClient.request(RegisterUserRequest(), requestBody: requestBody) { result in

+                case let .failure(error):
+                    completion(.failure(error))
+                }
             }
         }
     }
-}
-```
-
-```swift
-VersatileAPIClient.shared.registerUser(name: "Uhooi", description: "Green monster.") { result in
-    switch result {
-    case let .success(userID):
-        // Do something.
-    case let .failure(error):
