 ## Decision and Rationale
 
-To reduce the amount of time spent deploying and linking dependant packages, we combined [base](https://github.com/db-ui/base), [core](https://github.com/db-ui/core) and [elements](https://github.com/db-ui/elements) into a single monorepo, and evolved afterwards regarding new technologies (compare to ADR 01).

 ### Good to know
 
 1. You cannot use functions directly in a Mitosis component. A function has to be inside the `state`. So add your function to the `model.ts` `DBMyAwesomeComponentDefaultState`. Then you can define your component inside the `.tsx` file and use it in the `jsx` with `state.myAwsomeFunction()`.
-2. Try to enable multiple ways of data-binding: For example in `select` you are able to pass in a list of `<option>` via the `props.children` similiar to standard HTML composition, but we also give the developers the possibility to pass in a stripped down option list via another property: `options?: DBSelectOptionType[]`. We populate this with the internal `<For>` from Mitosis.

We populate this with the internal `<For>` from Mitosis.
    Why do we do this? We have multiple frameworks and all behave differently. With multiple ways of data-binding we try to provide a JS framework native experience as closely as we can.
 3. Try to parameterize a lot: For example if your component includes an icon button you should give it a text for accessibility. You should provide a default text, so it can't be empty, but you should also let the user change it with a property e.g. `iconButtonText`.
 4. To enable some native functionalities for Vue and Angular (`v-model` and `[(ng-model)]`) you might need to add some extra code to your component. At the generation process you might select `formValue` anyhow, but otherwise take a look at the `input` to see what you need to add to make this work.
