 ## Step 2: Configure the environment
 
-1.  Copy the environment configuration template:
+# Install
+
+#### ✅ 1. Install bun.
+
+The FHEVM Hardhat Template requires the popular [Bun](https://bun.sh) runtime to be installed.
+
+[Bun](https://bun.sh) is a modern and ultra-fast all-in-one JavaScript runtime — an alternative to Node.js + npm.
+
+Visit [https://bun.sh](https://bun.sh) for installation instructions.
+
+> [!Note]
+>
+> You can also use **npm** instead of Bun. In that case, replace commands like `bun <cmd>` with `npm <cmd>` and
+> `bunx <cmd>` with `npx <cmd>`.
+
+#### ✅ 2. Install the template dependencies.
 
-    ```sh
-    cp .env.example .env
-    ```
+```sh
+bun install
+```
 
-2.  Install project dependencies: Depending on your package manager, run one of the following:
+#### ✅ 3. Set up the `MNEMONIC` [Hardhat Configuration Variables](https://hardhat.org/hardhat-runner/docs/guides/configuration-variables).
 
-    ```sh
-    # Using npm
-    npm install
+```sh
+bunx hardhat vars set MNEMONIC
+? Enter value: ‣ #here is where your twelve words mnemonic should be put
+```
 
-    # Using yarn
-    yarn install
+- 🔐 Don’t have a `MNEMONIC`? Generate one at using Metamask or your favorite generator.

-    # Using pnpm
-    pnpm install
-    ```
+#### ✅ 4. Set up the `INFURA-PRIVATE-KEY` [Hardhat Configuration Variables](https://hardhat.org/hardhat-runner/docs/guides/configuration-variables).
+
+```sh
+bunx hardhat vars set INFURA-PRIVATE-KEY
+? Enter value: ‣ #here is where your private key should be put
+```

+- 🔐 Don’t have an `INFURA_PRIVATE_KEY`? You can get one at https://docs.metamask.io/services/get-started/infura/.
 
-## Project structure overview
+> [!IMPORTANT]
+>
+> You can enter `zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz` if you prefer not to set your `INFURA_PRIVATE_KEY`. If you choose to
+> do so, you will not be able to deploy & test on Sepolia Ethereum Testnet.
 
-- **`contracts/`**: Write your Solidity smart contracts here.
-- **`test/`**: Place your test scripts for smart contract testing.
-- **`deploy/`**: Deployment scripts for deploying your contracts.
-- **`hardhat.config.js`**: The pre-configured Hardhat setup file for deploying on Sepolia.
-- **`.env`:** The environment file that stores sensitive or environment-specific variables such as private keys and API keys.
+#### ❌ Hardhat Error Message
 
-To learn more about Hardhat, refer to the [official Hardhat documentation](https://hardhat.org/hardhat-runner/docs/getting-started#overview).
+If any of the requested Hardhat Configuration Variables is missing, you'll get an error message like this one:
 
----
+`Error HH1201: Cannot find a value for the configuration variable 'MNEMONIC'. Use 'npx hardhat vars set MNEMONIC' to set it or 'npx hardhat vars setup' to list all the configuration variables used by this project.`
