 RemoteData is an ADT (algebraic data type) described in [this article](https://medium.com/@gcanti/slaying-a-ui-antipattern-with-flow-5eed0cfb627b). Heavily based on [fp-ts](https://github.com/gcanti/fp-ts) lib.
 
 ### Installation
-`npm i --save @devexperts/remote-data-ts` 
+`npm i --save @devexperts/remote-data-ts`
 
 ### How to lift (wrap) your data in RemoteData:
 As you remember RemoteData is an union of few types: `RemoteInitial`, `RemotePending`, `RemoteFailure` and `RemoteSuccess`.
 
 While your data in **initial** or **pending** state just use `initial` or `pending` constant, because you don't have any **real** values in this case.
 
-```
+```ts
 import { initial, pending } from '@devexperts/remote-data-ts';
- 
+
 const customers = initial;
 // or
 const customers = pending;
 ```
-  
+
 When you receive data from server, use `failure` or `success` function, it depends on what you received:
-```
+
+```ts
 import { failure, success } from '@devexperts/remote-data-ts';
-import { apiClient } from 'apiClient'; 
+import { apiClient } from 'apiClient';
 import { TCustomer } from './MyModel';
- 
+
 const getCustomers = (): RemoteData<TCustomer[]> => {
    const rawData: TCustomer[] = apiClient.get('/customers');
-   
+
    try {
         const length = rawData.length;

 }

 ### How to fold (unwrap) your data from RemoteData:
 Finally you pass data to the component and want to render values, so now it's time to get our values back from RemoteData wrapper:
-```
+
+```ts
 import { NoData, Pending, Failure } from './MyPlaceholders';
 import { TCustomer } from './MyModel';
- 
+
 type TCustomersList = {
     entities: RemoteData<TCustomer[]>;
 };
- 
+
 const CustomersList: SFC<TCustomersList> = ({ entities }) => entities.foldL(
     () => <NoData />,
     () => <Pending />,
     err => <Failure error={err} />,
-    data => <ul>{data.map(item => <li>{item.name}</li>)}</ul>),
-)
-``` 
+    data => <ul>{data.map(item => <li>{item.name}</li>)}</ul>
+);
+```
