 # CodeGen
 
 This project aims to be able to generate Code from our Swagger / OpenAPI definitions.
+
+## Build
+
+* .NET 5 SDK has to be installed
+* `dotnet build src`
+
+## Usage
+
+* Execute the built CodeGen executable
+* You should find the output client definitions in the specified output folder (default. `Output`)
+
+## Implementation
+
+An abstract `CodeGenerator` has been implemented fully as a `CoscineCodeGenerator`.
+The idea is that with this abstraction someone can easily adapt and generate the code they want to produce.
