 ## About
 
-This project was initially for solving the issue [facebook/react-native#854](https://github.com/facebook/react-native/issues/854) because React Native lack of `Blob` implementation and it's problematic when transferring binary data. Now the project is committed to making file access and transfer easier, efficient for React Native developers. 
-We've implemented highly customizable filesystem and network module which plays well together. For example, upload and download data directly from/to storage which is much more efficient in some cases(especially for large ones). The file system supports file stream, so you don't have to worry about OOM problem when accessing large files.

 In `0.8.0` we introduced experimental Web API polyfills that make it possible to use browser-based libraries in React Native, such as, [FireBase JS SDK](https://github.com/wkh237/rn-firebase-storage-upload-sample)
