# Webview
2+
3+
A (new!) Java port of the [webview project](https://github.com/webview/webview). It uses JNA under the hood to interface with the webview library.
4+
5+
## How to use
6+
7+
1) Include the libary in your project (see the [JitPack page](https://jitpack.io/#Casterlabs/webview)).
8+
2) Copy and run the example in `Example.java`.
9+
3) Profit!
10+
11+
## TODO
12+
13+
Build our own DLLs and whatnot, the current ones are copied from the C# port.
