目前要kbar必須一次獲取整日kbar資料。是否能在Streaming新增訂閱Kbar onopen onclose events，在開新bar或收bar時收到資料就好，這樣速度比較快，server loading也比較低，謝謝。

Is your feature request related to a problem? Please describe.

Basically in the main ./README.md file, we have not mentioned/added any docs about how to use URL feed for custom font

Describe the solution you'd like

Simply add about the font docs to the README.md with an example snapshot

Additional context

Add all the images/snaps in the assets folder.
