Fork the github https://github.com/beaumoaj/components_and_props.git and clone YOUR COPY to your Ubuntu system.
Open an Ubuntu terminal window and cd into components_and_props
Run the following commands in the terminal window:
```
npm install
npm start
```
Wait for each command to finish. After the second command, your browser window should open and you will see a page that says:
```
Read the instructions to create components
```

You are now ready to start

Inside the src folder, create a new component called Greeting. Inside the component, declare a variable called name and assign it your name as a string value.
```
const name = "Tony";
```
This component should output the following header:
```
<h1>My name is {name} and I created this greeting</h1>
```
Inside App.js, find the line of code which says:
```
<p>Read the instructions to create components</p>
```
and replace it with a call to your new <Greeting/> component. Check that when you view the app, you see the greeting message. Open the developer tools and check for errors in the console.
Modify your Greeting component so that instead of using a local variable inside the component, you pass the name into the props for the component. Modify the component first. Make sure you add a props argument and then modify the variable declaration:
```
const name = {props.name};
```
Now edit App.js to ensure that you pass the name property. This is how I would pass my name to the greeting component.
```
<Greeting name="Tony"/>
```
