+# How to creating ERC20 token
+
+In recent years, the ERC20 token specification has become the defacto standard for Ethereum tokens. In other words, most Ethereum contracts out there today are ERC20-compliant. In this example you will learn how you can create your own Ethereum token by using [Truffle](https://www.trufflesuite.com/), [Ganache](https://www.trufflesuite.com/ganache) and [Openzeppelin](https://openzeppelin.com/) library.

+### Step 1: Step The Project Directory
+First of all we'll create a new project directory. Inside the root directory run the following commands:
+```sh 
+npm init -y
+```
+```sh 
+npm i -g truffle
+```
+```sh 
+npm i @openzeppelin/contracts
+```
+
+and then install [Ganache](https://www.trufflesuite.com/ganache) UI tool.

+### Step 2: Initialize a Truffle Project
+```sh 
+truffle init
