 ## Local Node Info
 
-To start, we will create a simple page that displays basic information from our local node.
+To get started, we will create a simple web page that displays basic information from our local node.
 
 ### Instructions
 
-Create a web page, `localNodeInfo.html` that loads an ethereum library, connects to a local node at `http://localhost:8545` and displays basic information :
+Create a web page called `localNodeInfo.html` that does the following:
 
-- In an element with (`id`=`chainId`), the number ID of the current network
-- In an element with `blockNumber` as `id` the number of blocks in the chain
+1. Loads an Ethereum library, such as `ethers.js` or `web3.js`.
+2. Connects to a local Ethereum node at `http://localhost:8545`.
+3. Displays the following information on the page:
+  - The ID of the current network in an element with `chainId` as `id`.
+  - The number of blocks in the chain in an element with `blockNumber` as `id`.

 ### Hint
 
-You can use any library such as `ethers.js` or `web3.js` to connect to your local node.
+🚫 Please be aware that the test environment restricts internet access for security reasons. Therefore, you need to download the library  and import it locally. 
 
-Automated tests check for elements with specific IDs, the design is up to you.
+🎨 Automated tests only check for the content of elements with specific IDs; the rest of the design is up to you.
 
-Minimal structure:
