-## Local Setup Prerequisites
- - The application currently supports **Node.js v14.x**. Please ensure that you are using this version of Node.js when developing. (use [nvm](https://github.com/nvm-sh/nvm#installing-and-updating) to switch between node versions)
-
 ## Contribute to Backend

 - Clone the `bigcapital` repository and `cd` into `bigcapital` directory.
- Create `.env` file by copying `.env.example` file to `.env`. (The ``.env.example`` file has all the necessary values of variables to start development directly).
-
-```
-cp .env.example .env
-```
-
 - Install all npm dependencies of the monorepo, you don't have to change directory to the `backend` package. just hit these command on root directory and it will install dependencies of all packages.
