+# How it works ?
+
+## The standard
+
+This is a ERC20 token so it has all the function you would expect from it.
+
+The getters :
+```Solidity
+// to get the full name of the token (in this case Kanel42)
+function name() public view returns (string)
+// to get the symbol of the token (in this case KNL42)
+function symbol() public view returns (string)
+// to get the number of decimals (number of token * 10^decimals to get the number of token)
+function decimals() public view returns (uint8) 
+// to get the total supply that can be minted (in this case 8000(000000))
+function totalSupply() public view returns (uint256)
+// to get the balance of an address
+function balanceOf(address _owner) public view returns (uint256 balance)
+// to know how much the _spender can send on behalf of the _owner
+function allowance(address _owner, address _spender) public view returns (uint256 remaining)
+```
+
+The member functions :
+```Solidity
+// to transfer tokens to another address (_to)
+function transfer(address _to, uint256 _value) public returns (bool success)
+// to transfer tokens on behalf of _from to another address (_to)
+function transferFrom(address _from, address _to, uint256 _value) public returns (bool success)
+// to approve a certain amount to a _spender that can send token on your behalf
+function approve(address _spender, uint256 _value) public returns (bool success)
+```
+
+Events:
+```Solidity
+// is sent when a transfer is successful
+event Transfer(address indexed _from, address indexed _to, uint256 _value)
+// is sent when an approval is successful
+event Approval(address indexed _owner, address indexed _spender, uint256 _value)
+```
+
+And there is also another function for minting the token:
+```Solidity
+// the _value determine how much to mint (in *(10^decimals))
+function mint(uint256 _value) public
+```
