 # Metaforums
 An online web-based discussion forum application
 
+
+## How to set up
+
+1. Make sure mod_rewrite is enabled on Apache.
+2. Create a MySQL / MariaDB database, and import Metaforums' schema (`schema.sql`) into the database.
+3. Modify backend/config.php and adjust the configuration as needed.
+4. Point the browser to `localhost`
+
 ## Project Structure
-This project is separated between the frontend and the backend application.
+
-- backend/
-  The backend of this application is written in PHP, and is API focused. 
-    - index.php
-      The main handler of backend functions. Handles routing, loading of Mitsumine services, and conversion of array responses to JSON.
-    - Mitsumine/
-      Mitsumine is a set of custom-written helper classes to consolidate frequently used code.
-      - Mitsumine/HTTP
-        Mitsumine HTTP contains a number of abstractions for HTTP, such as Request class
-      - Mitsumine/Services
-        Mitsumine Services contains a number of service classes for common functionality such as Database and Session.
-    - Application/
-      Application contains classes that are the core of the application itself
-      - Controllers/
-        Controllers contain controllers that return HTTP responses
-- frontend/
-  The frontend of this application, written in HTML and utilizes T
 - index.php
-  This index file allows serving both frontend and backend from one endpoint.
+  The main handler of backend functions. Handles routing, loading of Application services, and response handling.
-  
+- Application/
+  Application contains classes that are the core of the application itself
+  - Assets/
+    Assets contains buildable assets, for example source CSS.
+  - Controllers/
+    Controllers contain controllers that return HTTP responses
+  - Foundations/
+    Foundations are helper classes for various functions, such as an SQL query builder, and base model implementation;
+    - SQLHelper
+      Contains SQL escaping facilities.
+    - QueryBuilder
+      The SQL query builder.
+    - Model
+      The base model implementation. Contains common code for all models.
+  - HTTP
+    HTTP contains a number of abstractions for HTTP, such as Request class.
+  - Models/
+    Models contain database models.
+  - Services/
+    Services contains a number of service classes for common functionality such as Database and Session.
+    - Authentication
+      Provide auth related services.
+    - Config
+      Loads configuration and provides a facility to access the contents.
+    - Database
+      A service that centralizes database access.
+    - Email
+      A service for sending email.
+    - ServiceContainer
+      A service container that ensures every service is loaded once. 
+    - Session
+      A service that contains centralized session management.
+    - View
+      Provides view rendering facilities
+  - Static/
+    Static contains static files served directly by the application. For example, this contains built CSS.
+  - Views/
+    Views contains all views used by the application
