+/**
+ * @dev This is a base contract to aid in writing upgradeable contracts, or any kind of contract that will be deployed
+ * behind a proxy. Since proxied contracts do not make use of a constructor, it's common to move constructor logic to an
+ * external initializer function, usually called `initialize`. It then becomes necessary to protect this initializer
+ * function so it can only be called once. The {initializer} modifier provided by this contract will have this effect.
+ *
+ * The initialization functions use a version number. Once a version number is used, it is consumed and cannot be
+ * reused. This mechanism prevents re-execution of each "step" but allows the creation of new initialization steps in
+ * case an upgrade adds a module that needs to be initialized.
+ *
+ * For example:
+ *
+ * [.hljs-theme-light.nopadding]
+ * ```solidity
+ * contract MyToken is ERC20Upgradeable {
+ *     function initialize() initializer public {
+ *         __ERC20_init("MyToken", "MTK");
+ *     }
+ * }
+ *
+ * contract MyTokenV2 is MyToken, ERC20PermitUpgradeable {
+ *     function initializeV2() reinitializer(2) public {
+ *         __ERC20Permit_init("MyToken");
+ *     }
+ * }
+ * ```
+ *
+ * TIP: To avoid leaving the proxy in an uninitialized state, the initializer function should be called as early as
+ * possible by providing the encoded function call as the `_data` argument to {ERC1967Proxy-constructor}.
+ *
+ * CAUTION: When used with inheritance, manual care must be taken to not invoke a parent initializer twice, or to ensure
+ * that all initializers are idempotent. This is not verified automatically as constructors are by Solidity.
+ *
+ * [CAUTION]
+ * ====
+ * Avoid leaving a contract uninitialized.
+ *
+ * An uninitialized contract can be taken over by an attacker. This applies to both a proxy and its implementation
+ * contract, which may impact the proxy. To prevent the implementation contract from being used, you should invoke
+ * the {_disableInitializers} function in the constructor to automatically lock it when it is deployed:
+ *
+ * [.hljs-theme-light.nopadding]

+REMIX DEFAULT WORKSPACE
+
+Remix default workspace is present when:
+i. Remix loads for the very first time 
+ii. A new workspace is created with 'Default' template
+iii. There are no files existing in the File Explorer
+
+This workspace contains 3 directories:
+
+1. 'contracts': Holds three contracts with increasing levels of complexity.
+2. 'scripts': Contains four typescript files to deploy a contract. It is explained below.
+3. 'tests': Contains one Solidity test file for 'Ballot' contract & one JS test file for 'Storage' contract.
+
+SCRIPTS
+
+The 'scripts' folder has four typescript files which help to deploy the 'Storage' contract using 'web3.js' and 'ethers.js' libraries.
+
+For the deployment of any other contract, just update the contract's name from 'Storage' to the desired contract and provide constructor arguments accordingly 
+in the file `deploy_with_ethers.ts` or  `deploy_with_web3.ts`
+
+In the 'tests' folder there is a script containing Mocha-Chai unit tests for 'Storage' contract.
+
+To run a script, right click on file name in the file explorer and click 'Run'. Remember, Solidity file must already be compiled.
+Output from script will appear in remix terminal.
+
+Please note, require/import is supported in a limited manner for Remix supported modules.
+For now, modules supported by Remix are ethers, web3, swarmgw, chai, multihashes, remix and hardhat only for hardhat.ethers object/plugin.
+For unsupported modules, an error like this will be thrown: '<module_name> module require is not supported by Remix IDE' will be shown.
