+> If you like this project, follow me on Twitter [@bliashenko](https://twitter.com/bliashenko) to hear about things I am building. 
+
+## Codecrumbs v2
+Check out new version of this project as [standalone application](https://codecrumbs.io). Just in a few clicks you can start exploring a codebase in more efficient way, create interactive visual guides and share them with others on your own blog! See [quick guide here](https://codecrumbs.io/guides/web-app-with-github/).

+## Demo
+Check out prepared example for [**standalone version running here**](https://codecrumbs.io/app).
+
+## Codecrumbs v1
+
 >**How it works?** You run `codecrumbs` command for a codebase, it analyzes source code and builds its visual representation. Write down a codecrumb-comment and codebase state will be reflected by visual client in browser on the fly.

 ### Multi-codebase integration
 You might be interested to study connections between several codebases (sub-modules), codecrumbs supports that.
 Simply start codecrumbs multiple times (once for each codebase), it all **will be synced in one picture** inside the browser tab. To control a diagram UI - select it by clicking on it.

-
-You can take a snapshot of application state at any point of time and share it with others. Simply download the json file of codecrumbs store (*top-right corner, "setup -> download"*). This json file can be then uploaded to codecrumbs (*top-right corner, "setup -> upload"*) to represent exactly same picture, even without having that project locally!

 Next features are developing:
-- **eject codecrumbs** - ability to remove all "breadcrumbs" from source code in "one click"
-- **data transferring between cc trail steps**
 - **VS Code extension** - some neat features right inside the code editor. Checkout [the repo here](https://github.com/Bogdan-Lyashenko/vs-code-codecrumbs).
