 It originated from the need of a flexible tool for physicists at CERN to create their custom forms in the [CERN Analysis Preservation](https://github.com/cernanalysispreservation/analysispreservation.cern.ch) application (a process that was originally done by the CAP team who had to manually define the JSON schemas for every member experiment) in a zero-code fashion. This tool proved to be very useful for us to more easily scalate and expand, reaching a wider audience here at CERN. So, we thought it could also be useful for other people and decided to decouple it from CAP and release it as an open source library.

 - **`getFormuleState`**: Formule has its own internal redux state. You can retrieve it at any moment if you so require for more advanced use cases. If you want to continuosly synchronize the Formule state in your app, you can pass a callback function to FormuleContext instead (see below), which will be called every time the form state changes.
 
 ### Field types
 
 Formule includes a variety of predefined field types, grouped in three categories:
+
 - **Simple fields**: `Text`, `Text area`, `Number`, `Checkbox`, `Switch`, `Radio`, `Select` and `Date` fields.
 - **Collections**:
   - `Object`: Use it of you want to group fields or to add several of them inside of a `List`.

 ### Syncing Formule state
+
 If you want to run some logic in your application every time the current Formule state changes in any way (e.g. to run some action every time a new field is added to the form) you can pass a function to be called back when that happens:
 
 ```jsx
-const handleFormuleStateChange = newState => {
