 Core-JS defines custom functions for the **Wisemapping** ecosystem.
 
-## Quick Start
-
-1. Clone repository with the next command:
-
-```
-git clone https://[username]@bitbucket.org/wisemapping/wisemapping-frontend.git
-```
-
-where the variable _username_ is you username of Bitbucket.
-
-_Note:The project is configured to use the yarn dependency manager_
-
-2. Move to folder core-js
-
-```
-cd packages/core-js
-```
-
-3. Now you need install all dependence, this is done with command `yarn install`
-
-4. To start the development enviroment you have to use command `yarn start`.
-
 ## Production
 
 To build up the package core-js and use in production, you have to use command `yarn build`
