 ## Features
 - Transfer data directly from/to storage without BASE64 bridging
 - To send binary data, you have two choices, use BASE64 encoded string or a file path which points to a file contains the body. The `Content-Type` header does not matters.
  - The body is a BASE64 encoded string, the `Content-Type` header filed must containing substring`;BASE64` or `application/octet`  
  - The body is a path point to a file, it must be a string starts with `RNFetchBlob-file://`, which can simply done by `RNFetchBlob.wrap(PATH_TO_THE_FILE)`
-- To send the body as-is, set a `Content-Type` header not containing `;BASE64` or `application/octet`.

 ### Web API Polyfills
 
-After `0.8.0` we've made some [Web API polyfills](https://github.com/wkh237/react-native-fetch-blob/wiki/Web-API-Polyfills-(work-in-progress)) that makes some browser-based library available in RN.

 - Blob
 - XMLHttpRequest (Use our implementation if you're going to use it with Blob)
 
 **Concate and Replacing Files**
 
-If you're going to concatenate files, you don't have to read the data to JS context anymore ! In `0.8.0` we introduced new encoding `uri` for writeFile and appendFile API. Which make it possible to done the whole process in native.
