    description:
      "<p>The ERC20 is a smart contract standard made for fungible tokens (i.e: interchangeable tokens like coins). The fixed supply version of this standard guarantees no token will ever be created after the initial emission. Therefore some flexibility is sacrificed for the sake of more trust towards the token.</p> <p>Parameters :</p> <ul> <li><strong>Name</strong> : This is the name of your smart contract which will be reflected on-chain.</li> <li><strong>Symbol</strong> : This is the symbol associated to the NFT collection</li> <li><strong>Initial Supply</strong> : Initial amount of token emitted at the smart contract creation. You should add 18 trailing zeros to compensate the number of digits reserved to decimals.</li> </ul>",

The best way to achieve this is by\n * using `public constant` hash digests:\n *\n * ```\n * bytes32 public constant MY_ROLE = keccak256("MY_ROLE");\n * ```\n *\n * Roles can be used to represent a set of permissions. To restrict access to a\n * function call, use {hasRole}:\n *\n * ```\n * function foo() public {\n *     require(hasRole(MY_ROLE, msg.sender));\n *     ...\n * }\n * ```\n *\n * Roles can be granted and revoked dynamically via the {grantRole} and\n * {revokeRole} functions. Each role has an associated admin role, and only\n * accounts that have a role\'s admin role can call {grantRole} and {revokeRole}.\n *\n * By default, the admin role for all roles is `DEFAULT_ADMIN_ROLE`, which means\n * that only accounts with this role will be able to grant or revoke other\n * roles. More complex role relationships can be created by using\n * {_setRoleAdmin}.\n *\n * WARNING: The `DEFAULT_ADMIN_ROLE` is also its own admin: it has permission to\n * grant and revoke this role.

The fixed supply version of this standard guarantees no token will ever be created after the initial emission.

You should add 18 trailing zeros to compensate the number of digits reserved to decimals.</li> </ul>",

      '<p>The ERC721 is a smart contract standard which is specialised in single-copy Non Fungible Tokens (NFT).\n\t\t\tWithin this standard, tokens are linked to addresses (the owners) and to URIs (references of the NFT contents).</p>\n\t\t\t<p>It is important to notice that we do not store any content directly inside the smart contract.\n\t\t\tOnly references are stored. It is up to the smart contract readers to find the content by themselves using the references.</p>\n\t\t\t<p>Starton provides an <a href="https://app.starton.io/ipfs">IPFS integration</a> in case you need to host your NFT contents.</p>\n\t\t\t<p>Parameters :</p>\n\t\t\t<ul>\n\t\t\t<li><strong>Name</strong> : This is the name of your smart contract which will be reflected on-chain.</li>\n\t\t\t<li><strong>Symbol</strong> : This is the symbol associated to the NFT collection</li>\n\t\t\t<li><strong>BaseUri</strong> : Will be used to concatenate NFT URIs and the ContractUriSuffix<ul>\n\t\t\t<li>Using IPFS: it should be <code>ipfs://ipfs/</code></li>\n\t\t\t<li>Using a centralised server: it should be like <code>https://yourapi.com/endpoint/</code></li>\n\t\t\t</ul>\n\t\t\t</li>\n\t\t\t<li><strong>ContractUriSuffix</strong> (will be concatenated with baseUri):<ul>\n\t\t\t<li>Using IPFS: it is the CID of the contract metadata (more info <a href="https://docs.opensea.io/docs/contract-level-metadata">here</a>)</li>\n\t\t\t<li>Using a centralised server: the path of the contract metadata json</li>\n\t\t\t</ul>\n\t\t\t</li>\n\t\t\t</ul>',

Each role has an associated admin role, and only\n * accounts that have a role\'s admin role can call {grantRole} and {revokeRole}.\n *\n * By default, the admin role for all roles is `DEFAULT_ADMIN_ROLE`, which means\n * that only accounts with this role will be able to grant or revoke other\n * roles. More complex role relationships can be created by using\n * {_setRoleAdmin}.\n *\n * WARNING: The `DEFAULT_ADMIN_ROLE` is also its own admin: it has permission to\n * grant and revoke this role.
