 ### 📌 **Tasks**:
 
-- Create a [metamask](https://metamask.io/) account and fund it with some Goerli ETH.
-  - You can use the [faucet](https://goerlifaucet.com/) to get some Goerli ETH.
+- 📡 Download [Metamask](https://metamask.io) and create an account if you don't already have one. It is the most popular Ethereum wallet and allows you to interact with the Ethereum blockchain.
+- Get your RPCURL on [Alchemy](https://dashboard.alchemy.com/apps).
+  - Sign in.
+  - Click on `Create new app` and enter the project name.
+  - Go to network, select `Ethereum`, change `mainnet` to `Sepolia`, and copy the URL.
+- Add the Sepolia Testnet network to Metamask. [Here's](https://moralis.io/how-to-add-the-sepolia-network-to-metamask-full-guide/) a guide on how to do it.
+- Go to the [Sepolia faucet](https://www.alchemy.com/faucets/ethereum-sepolia), enter your wallet address, and send yourself some ETH.
+  > ⚠️ You need some ETH on the mainnet to receive test tokens. If you don't have any, contact the workshop manager.
 
-- Create an account on [Infura](https://infura.io/) and get an API key.
-  - You will use this API key to interact with the Goerli testnet.
+> You can now broadcast transactions to the Sepolia testnet, by the endpoint `https://eth-sepolia.g.alchemy.com/v2/<API_KEY>`.
 
-> You can now broadcast transactions to the Goerli testnet, by the endpoint `https://goerli.infura.io/v3/<YOUR_API_KEY>`.
-
-- Now deploy and interact with your contract, like you did in the previous steps, but this time on the Goerli testnet.
-> Don't forget to use your endpoint, shutdown your local blockchain to be sure you are using the Goerli testnet.
