-# 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.
