-
----
-### Stoppable
-Base contract that provides an emergency stop mechanism.
-
-Inherits from contract Ownable.
-
-#### emergencyStop( ) external onlyOwner
-Triggers the stop mechanism on the contract. After this function is called (by the owner of the contract), any function with modifier stopInEmergency will not run.
-
-#### modifier stopInEmergency
-Prevents function from running if stop mechanism is activated.
-
-#### modifier onlyInEmergency

-
-#### transfer(address newOwner) onlyOwner
-Sets the passed address as the pending owner.
-
-#### modifier onlyPendingOwner
-Function only runs if called by pending owner.
-
-#### claimOwnership( ) onlyPendingOwner

-___
-### Migrations
-Base contract that allows for a new instance of itself to be created at a different address.
-
-Inherits from contract Ownable.
-
-#### upgrade(address new_address) onlyOwner
-Creates a new instance of the contract at the passed address.
-
-#### setCompleted(uint completed) onlyOwner
-Sets the last time that a migration was completed.
-
-___
-### SafeMath
-Provides functions of mathematical operations with safety checks.
-
-#### assert(bool assertion) internal
-Throws an error if the passed result is false. Used in this contract by checking mathematical expressions.
-
-#### safeMul(uint a, uint b) internal returns (uint)
-Multiplies two unisgned integers. Asserts that dividing the product by the non-zero multiplicand results in the multiplier.
-
-#### safeSub(uint a, unit b) internal returns (uint)
-Checks that b is not greater than a before subtracting.
-
-#### safeAdd(unit a, unit b) internal returns (uint)
-Checks that the result is greater than both a and b.
-
-___
-### LimitBalance
-
-Base contract that provides mechanism for limiting the amount of funds a contract can hold.
-
-#### LimitBalance(unit _limit)
-Constructor takes an unisgned integer and sets it as the limit of funds this contract can hold.
-
-#### modifier limitedPayable()
-Throws an error if this contract's balance is already above the limit.
-
-___
-### PullPayment
-Base contract supporting async send for pull payments.
-Inherit from this contract and use asyncSend instead of send.
-
-#### asyncSend(address dest, uint amount) internal
-Adds sent amount to available balance that payee can pull from this contract, called by payer.
-
-#### withdrawPayments( )
-Sends designated balance to payee calling the contract. Throws error if designated balance is 0, if contract does not hold enough funds ot pay the payee, or if the send transaction is not successful.
-
-___
-### StandardToken
-Based on code by FirstBlood: [FirstBloodToken.sol]
-
-Inherits from contract SafeMath. Implementation of abstract contract ERC20 (see https://github.com/ethereum/EIPs/issues/20)
-
-[FirstBloodToken.sol]: https://github.com/Firstbloodio/token/blob/master/smart_contract/FirstBloodToken.sol
-
-#### approve(address _spender, uint _value) returns (bool success)
-Sets the amount of the sender's token balance that the passed address is approved to use.
-
-###allowance(address _owner, address _spender) constant returns (uint remaining)
-Returns the approved amount of the owner's balance that the spender can use.
-
-###balanceOf(address _owner) constant returns (uint balance)
-Returns the token balance of the passed address.
-
-###transferFrom(address _from, address _to, uint _value) returns (bool success)
-Transfers tokens from an account that the sender is approved to transfer from. Amount must not be greater than the approved amount or the account's balance.
-
-###function transfer(address _to, uint _value) returns (bool success)
-Transfers tokens from sender's account. Amount must not be greater than sender's balance.
-
-___
-### BasicToken
-Simpler version of StandardToken, with no allowances
-
-#### balanceOf(address _owner) constant returns (uint balance)
-Returns the token balance of the passed address.
-
-###function transfer(address _to, uint _value) returns (bool success)
-Transfers tokens from sender's account. Amount must not be greater than sender's balance.

-
-#### createTokens(address recipient) payable
-Creates tokens based on message value and credits to the recipient.
-
-#### getPrice() constant returns (uint result)
-Returns the amount of tokens per 1 ether.
-
-
-___
-### Bounty
-To create a bounty for your contract, inherit from the base `Bounty` contract and provide an implementation for `deployContract()` returning the new contract address.
-
-```
-import {Bounty, Target} from "./zeppelin/Bounty.sol";
-import "./YourContract.sol";
-
-contract YourBounty is Bounty {
-  function deployContract() internal returns(address) {
-    return new YourContract()
-  }
-}
-```
-
-Next, implement invariant logic into your smart contract.
-Your main contract should inherit from the Target class and implement the checkInvariant method. This is a function that should check everything your contract assumes to be true all the time. If this function returns false, it means your contract was broken in some way and is in an inconsistent state. This is what security researchers will try to acomplish when trying to get the bounty.
-
-At contracts/YourContract.sol
-
-```
-import {Bounty, Target} from "./zeppelin/Bounty.sol";
-contract YourContract is Target {
-  function checkInvariant() returns(bool) {
-    // Implement your logic to make sure that none of the invariants are broken.
-  }
-}
-```
-
-Next, deploy your bounty contract along with your main contract to the network.
-
-At `migrations/2_deploy_contracts.js`
-
-```
-module.exports = function(deployer) {
-  deployer.deploy(YourContract);
-  deployer.deploy(YourBounty);
-};
-```
-
-Next, add a reward to the bounty contract
-
-After deploying the contract, send reward funds into the bounty contract.
-
-From `truffle console`
-
-```
-bounty = YourBounty.deployed();
-address = 0xb9f68f96cde3b895cc9f6b14b856081b41cb96f1; // your account address
-reward = 5; // reward to pay to a researcher who breaks your contract
-
-web3.eth.sendTransaction({
-  from: address,
-  to: bounty.address,
-  value: web3.toWei(reward, "ether")
-})
-
-```
-
-If researchers break the contract, they can claim their reward.
-
-For each researcher who wants to hack the contract and claims the reward, refer to our [test](./test/Bounty.js) for the detail.
-
-Finally, if you manage to protect your contract from security researchers, you can reclaim the bounty funds. To end the bounty, kill the contract so that all the rewards go back to the owner.
-
-```
-bounty.kill();
-```

+Truffle Beta Support
+""""""""""""""""""""""""
+We also support Truffle Beta npm integration. If you're using Truffle Beta, the contracts in ``node_modules`` will be enough, so feel free to delete the copies at your ``contracts`` folder. If you're using Truffle Beta, you can use Zeppelin contracts like so::
+
+	import "zeppelin-solidity/contracts/Ownable.sol";
+
+	contract MyContract is Ownable {
+	  ...
+	}
+
+For more info see the `Truffle Beta package management tutorial <http://truffleframework.com/tutorials/package-management/>`_.
