 # Ho to use the Web API version
-This Installation adds all HopFrame [endpoints](./endpoints.md) and [services](./services.md) to the application.
+This Installation adds all HopFrame [endpoints](./endpoints.md) and [repositories](../repositories.md) to the application.
 
 1. Add the HopFrame.Api library to your project:

+# LogicResults
+LogicResults provide another layer of abstraction above the ActionResults.
+They help you sending the right `HttpStatusCode` with the right data.
+
+## Usage
+1. Create an endpoint that returns an `ActionResult`:
+
+    ```csharp
+    [HttpGet("hello")]
+    public ActionResult<string> Hello() {
+        return new ActionResult<string>("Hello, World!");
+    }
+    ```
+2. Now instead of directly returning the `ActionResult`, return a `LogicResult`
+
+    ```csharp
+    [HttpGet("hello")]
+    public ActionResult<string> Hello() {
+        return LogicResult<string>.Ok("Hello, World!");
+    }
+    ```
+3. This allows you to very easily change the return type by simply calling the right function
+
+    ```csharp
+    [HttpGet("hello")]
+    public ActionResult<string> Hello() {
+        if (!Auth.IsLoggedIn)
+            return LogicResult<string>.Forbidden();
+
+        return LogicResult<string>.Ok("Hello, World!");
+    }
+    ```
+    **Hint:** You can also provide an error message for status codes that are not in the 200 range.

+# Auth Service
+The `IAuthService` provides some useful methods to handle user authentication (login/register).
+
+## Usage
+Simply define the `IAuthService` as a dependency
+
+```csharp
+public interface IAuthService {
+    Task Register(UserRegister register);
+    Task<bool> Login(UserLogin login);
+    Task Logout();
+
+    Task<Token> RefreshLogin();
+    Task<bool> IsLoggedIn();
+}
+```
+## Automatically refresh user sessions
+1. Make sure you have implementented the `AuthMiddleware` how it's described in step 5 of the [installation](./installation.md).
+
+2. After that, the access token of the user gets automatically refreshed as long as the refresh token is valid.

+# HopFrame Repositories
+The HopFrame provies repositories for the various build in database models as an abstraction around the `HopDbContext` to ensure, that the data is proccessed and saved correctly.
+
+## Overview
+The repositories can also be used by simply defining them as a dependency in your service / controller.
+
+### User Repository
+
+```csharp
+public interface IUserRepository {
+    Task<IList<User>> GetUsers();
+
+    Task<User> GetUser(Guid userId);
+
+    Task<User> GetUserByEmail(string email);
+
+    Task<User> GetUserByUsername(string username);
+    
+    Task<User> AddUser(User user);
+    
+    Task UpdateUser(User user);
+
+    Task DeleteUser(User user);
+
+    Task<bool> CheckUserPassword(User user, string password);
+
+    Task ChangePassword(User user, string password);
+}
+```
+
+### Group Repository
+
+```csharp
+public interface IGroupRepository {
+    Task<IList<PermissionGroup>> GetPermissionGroups();
+
+    Task<IList<PermissionGroup>> GetDefaultGroups();
+
+    Task<IList<PermissionGroup>> GetUserGroups(User user);
+
+    Task<PermissionGroup> GetPermissionGroup(string name);
+
+    Task EditPermissionGroup(PermissionGroup group);
+
+    Task<PermissionGroup> CreatePermissionGroup(PermissionGroup group);
+
+    Task DeletePermissionGroup(PermissionGroup group);
+}
+```
+
+### Permission Repository
+
+```csharp
+public interface IPermissionRepository {
+    Task<bool> HasPermission(IPermissionOwner owner, params string[] permissions);
+    
+    Task<Permission> AddPermission(IPermissionOwner owner, string permission);
+    
+    Task RemovePermission(IPermissionOwner owner, string permission);
+
+    Task<IList<string>> GetFullPermissions(IPermissionOwner owner);
+}
+```
+
+### Token Repository
+
+```csharp
+public interface ITokenRepository {
+    Task<Token> GetToken(string content);
+
+    Task<Token> CreateToken(int type, User owner);
+
+    Task DeleteUserTokens(User owner);
+}
+```
