+    This is the manual for the financer application - a simple app to support you in managing your personal finances.
+
+    The main goal of the financer application is to keep things simple by not attempting to provide sophisticated
+    automation. Instead it is merely a tool that provides basic key values to support you.

     3. Architectural overview
     =========================
+    The financer application currently consists of two components - a server and a client. They communicate via a JSON
+    REST API. The only available client is a web client that supports a boiled down view for mobile devices, though.
+
+    Both client (-web-client) and server (-server) reside in dedicated Maven modules, with a common (-common) module
+    that holds common model classes and DTOs. Both components are layered:

     6. Account groups
     =================
+    Account groups are a simple way to group account into topics. Imagine the following accounts:
+     - Rent
+     - Electricity
+     - Water
+     - Groceries
+     - Takeaway
+     - Coffee shop
+     - Cinema
+     - Netflix
+
+    They could be grouped via the following three groups:
+     - Housing for Rent, Electricity and Water
+     - Food for Groceries, Takeaway and Coffee shop
+     - Entertainment for Cinema and Netflix
+
+    This additional hierarchy level is actively used by reports to provide a better picture about where money is spent.
+    The financer application makes no hard guidelines on how to model your accounts and account groups, so you can model
+    them matching your needs.
