-**A library for secure smart contract development.** Build on a solid foundation of community-vetted code.
-
- * Implementations of standards like [ERC20](https://docs.openzeppelin.com/contracts/erc20) and [ERC721](https://docs.openzeppelin.com/contracts/erc721).
- * Flexible [role-based permissioning](https://docs.openzeppelin.com/contracts/access-control) scheme.

- * First-class integration with the [Gas Station Network](https://docs.openzeppelin.com/contracts/gsn) for systems with no gas fees!
- * [Audited](https://github.com/OpenZeppelin/openzeppelin-contracts/tree/master/audit) by leading security firms (_last full audit on v2.0.0_).
-
-## Overview
-
-### Installation
-
-```console
-$ npm install @openzeppelin/contracts
-```
-
-OpenZeppelin Contracts features a [stable API](https://docs.openzeppelin.com/contracts/releases-stability#api-stability), which means your contracts won't break unexpectedly when upgrading to a newer minor version.
-
-### Usage
-
-Once installed, you can use the contracts in the library by importing them:
-
-```solidity
-pragma solidity ^0.6.0;
-
-import "@openzeppelin/contracts/token/ERC721/ERC721.sol";
-
-contract MyCollectible is ERC721 {
-    constructor() ERC721("MyCollectible", "MCO") public {
-    }
-}
-```
-
-_If you're new to smart contract development, head to [Developing Smart Contracts](https://docs.openzeppelin.com/learn/developing-smart-contracts) to learn about creating a new project and compiling your contracts._
-
-To keep your system secure, you should **always** use the installed code as-is, and neither copy-paste it from online sources, nor modify it yourself. The library is designed so that only the contracts and functions you use are deployed, so you don't need to worry about it needlessly increasing gas costs.
-
-## Learn More
-
-The guides in the [docs site](https://docs.openzeppelin.com/contracts) will teach about different concepts, and how to use the related contracts that OpenZeppelin Contracts provides:
-
-* [Access Control](https://docs.openzeppelin.com/contracts/access-control): decide who can perform each of the actions on your system.
-* [Tokens](https://docs.openzeppelin.com/contracts/tokens): create tradeable assets or collectives, and distribute them via [Crowdsales](https://docs.openzeppelin.com/contracts/crowdsales).
-* [Gas Station Network](https://docs.openzeppelin.com/contracts/gsn): let your users interact with your contracts without having to pay for gas themselves.
-* [Utilities](https://docs.openzeppelin.com/contracts/utilities): generic useful tools, including non-overflowing math, signature verification, and trustless paying systems.
-
-The [full API](https://docs.openzeppelin.com/contracts/api/token/ERC20) is also thoroughly documented, and serves as a great reference when developing your smart contract application. You can also ask for help or follow Contracts's development in the [community forum](https://forum.openzeppelin.com).
-
-Finally, you may want to take a look at the [guides on our blog](https://blog.openzeppelin.com/guides), which cover several common use cases and good practices.. The following articles provide great background reading, though please note, some of the referenced tools have changed as the tooling in the ecosystem continues to rapidly evolve.
-
-* [The Hitchhiker’s Guide to Smart Contracts in Ethereum](https://blog.openzeppelin.com/the-hitchhikers-guide-to-smart-contracts-in-ethereum-848f08001f05) will help you get an overview of the various tools available for smart contract development, and help you set up your environment.
-* [A Gentle Introduction to Ethereum Programming, Part 1](https://blog.openzeppelin.com/a-gentle-introduction-to-ethereum-programming-part-1-783cc7796094) provides very useful information on an introductory level, including many basic concepts from the Ethereum platform.
-* For a more in-depth dive, you may read the guide [Designing the Architecture for Your Ethereum Application](https://blog.openzeppelin.com/designing-the-architecture-for-your-ethereum-application-9cec086f8317), which discusses how to better structure your application and its relationship to the real world.
-
-## Security
-
-This project is maintained by [OpenZeppelin](https://openzeppelin.com), and developed following our high standards for code quality and security. OpenZeppelin is meant to provide tested and community-audited code, but please use common sense when doing anything that deals with real money! We take no responsibility for your implementation decisions and any security problems you might experience.
-
-The core development principles and strategies that OpenZeppelin is based on include: security in depth, simple and modular code, clarity-driven naming conventions, comprehensive unit testing, pre-and-post-condition sanity checks, code consistency, and regular audits.
-
-The latest audit was done on October 2018 on version 2.0.0.
-
-Please report any security issues you find to security@openzeppelin.org.

-/**
- * @dev Contract module that allows children to implement role-based access
- * control mechanisms.
- *
- * Roles are referred to by their `bytes32` identifier. These should be exposed
- * in the external API and be unique. The best way to achieve this is by
- * using `public constant` hash digests:
- *
- * ```
- * bytes32 public constant MY_ROLE = keccak256("MY_ROLE");
- * ```
- *
- * Roles can be used to represent a set of permissions. To restrict access to a
- * function call, use {hasRole}:
- *
- * ```
- * function foo() public {
- *     require(hasRole(MY_ROLE, msg.sender));
- *     ...
- * }
- * ```
- *
- * Roles can be granted and revoked dynamically via the {grantRole} and
- * {revokeRole} functions. Each role has an associated admin role, and only
- * accounts that have a role's admin role can call {grantRole} and {revokeRole}.
- *
- * By default, the admin role for all roles is `DEFAULT_ADMIN_ROLE`, which means
- * that only accounts with this role will be able to grant or revoke other
- * roles. More complex role relationships can be created by using
- * {_setRoleAdmin}.
- *
- * WARNING: The `DEFAULT_ADMIN_ROLE` is also its own admin: it has permission to
- * grant and revoke this role. Extra precautions should be taken to secure
- * accounts that have been granted it.
