+# Practical-1: MetaMask Installation and Ether Spending Study
+
+## Step 1: Install MetaMask
+
+### For Desktop (Browser)
+
+1. Open your preferred browser (Chrome, Firefox, Edge, or Brave).
+2. Go to the official MetaMask website: [https://metamask.io](https://metamask.io)
+3. Click **"Download"** and select your browser.
+4. Add the extension to your browser.
+5. Open MetaMask, and follow the setup:
+   - **Create a new wallet** or **import an existing one**.
+   - Set a **strong password**.
+   - **Backup your secret recovery phrase** securely.
+
+### For Mobile
+
+1. Go to your App Store (iOS) or Google Play Store (Android).
+2. Search for **MetaMask**.
+3. Download and install the app.
+4. Follow similar setup steps (create wallet, backup phrase).
+
+## Step 2: Connect MetaMask to a Network
+
+- By default, MetaMask uses the **Ethereum Mainnet**.
+- To use test networks for learning, click the network dropdown and select a testnet like **Goerli Test Network**.
+- Obtain free test Ether from a Goerli faucet: [https://goerlifaucet.com/](https://goerlifaucet.com/).
+
+## Step 3: Understanding Ether Spending per Transaction
+
+### Key Concepts
+1. **Gas Limit:** Maximum units of gas you are willing to spend.
+2. **Gas Price:** Price per gas unit in **Gwei** (1 ETH = 1,000,000,000 Gwei).
+3. **Transaction Fee = Gas Limit × Gas Price**
+
+## Step 4: Make a Test Transaction
+
+1. Ensure your wallet has ETH (test ETH on testnets).
+2. Click **Send** in MetaMask.
+3. Enter the recipient address and amount.
+4. Adjust **Gas Fee** if desired.
+5. Confirm the transaction.
+
+## Step 5: Observe Spending
+
+- After sending, MetaMask displays the **Transaction Fee** in ETH.
+- To see detailed info, check **Etherscan**:
+  1. Copy the transaction hash from MetaMask.
+  2. Go to [https://etherscan.io](https://etherscan.io) or testnet explorer like [https://goerli.etherscan.io](https://goerli.etherscan.io).
+  3. Paste the hash to see gas used and ETH spent.
+
+## Step 6: Experiment
+
+- Send multiple transactions with different **gas prices**.
+- Observe how fees change based on **network congestion**.
+- Try interacting with **smart contracts** to see higher gas usage.
+
+## Tips
+- Always use a testnet first to avoid losing real ETH.
+- MetaMask provides detailed transaction history and gas usage.
