diff: +# ADR006: Avoid React.FC
  +## Context
  +
  +Facebook has removed ```React.FC``` from their base template for a Typescript project. The reason for this was that it was found to be an unnecessary feature with next to no benefits in combination with a few downsides.
  +
  +The main reasons were:
  +- **children props** were implicitly added
  +- **Generic Type** lacked support
  +
  +## Decision
  +
  +To keep our codebase up to date, we have decided that React.FC should be avoided in our codebase when adding new code.
  +
  +Here is an example:
  +````
  +type MyType = { text: string }
  +
  +// avoid React.FC
  +const ComponentWithReactFC = React.FC<MyType> = ({text} => <div>{text}</div>)
  +
  +// do this instead
  +const ComponentWithoutReactFC = ({text} : MyType) => <div>{text}</div>
  +````
  +
  +## Consequences
  +
  +We will gradually remove the current usage of React.FC from our codebase.
