-- Strongly-type your variables. This improves readability.
-```csharp
-var xyz = Object.GetSomething(); //Do not do this. What type is xyz (without looking at Method returns etc.)?
-Manga[] zyx = Object.GetAnotherThing(); //I can now easily see that zyx is an Array.

-Tranga is using a code-first Entity-Framework Core approach. If you modify the db-table structure you need to create a migration.

+      ```csharp
+      Manga[] zyx = Object.GetAnotherThing(); //I can see that zyx is an Array, without digging through more code

+    - **DO _NOT_**
+      ```csharp
+      var xyz = Object.GetSomething(); //What is xyz? An Array? A string? An object?

 1. Copy one of the existing connectors, or start from scratch and inherit from `API.Schema.MangaConnectors.MangaConnector`.
 2. Add the new Connector as Object-Instance in `Tranga.cs` to the MangaConnector-Array `connectors`.
