+# Usage
+
+Because it is a ERC20 token you can use it with any wallet that support the standard, like MetaMask, Rabby, and a lot more...
+
+## Mint it
+
+You can call the function `mint(uint256)` and giving it a number of token (in *10^decimals). And then you will be credited with the corresponding tokens.
+
+## To use it
+
+You can make transfer it and check your balance via any wallet ERC20 compatible. You can also send an `approve(address _spender, uint _value)` to approve another address to send on your behalf, so they can use `transferFrom(address _from, address _to, uint256 _value)` to make transfer from your address. \
+You can also check if transfer or approval occurs via the corresponding events.
