 A debugging tool for React. Records state whenever state is changed and allows user to jump to any previous recorded state.
 
 Two parts are needed for this tool to function. The chrome extension must be installed, and the NPM package must be installed and used in the React code.

+After installing both the Chrome extension and the npm package, just open up your project in the browser.
 
 Then open up your Chrome DevTools. There'll be a new tab called React-Time-Travel.
 
 ## Features
 
 ### Recording
 
-Whenever state is changed (whenever setState is called), this extension will create a snapshot of the current state tree and record it. Each snapshot will be displayed in Chrome DevTools under the React-Time-Travel panel.

 ### Others
 
-Other handy features include: 
-* multiple tabs support
-* a slider to move through snapshots quickly
-* a play button to move through snapshots automatically
-* a pause which button stops recording each snapshot
-* a lock button to freeze the DOM in place. setState will lose all functionality while the extension is locked
-* a persist button to keep snapshots upon refresh. handy when changing code and debugging
-* export/import the current snapshots in memory
