Hello World

In this part we will install `fastn` on your machine and create a hello world `fastn` program.
The name of package manager for `fastn` language is [`fastn`](https://fastn.com). We will begin by installing `fastn` on your machine. [`Install fastn`](https://fastn.com/install/). You can open installation page in a new tab, and follow the instructions. You can continue this course after installing `fastn`.

Let's create our Hello World program

Let's create a `fastn` package and start coding Hello World.
ℹ️
What is `fastn` package?
`fastn` package is a folder that requires atleast two files - FASTN.ftd - index.ftd There can be any number of `.ftd` file but these two files are essential.
Create a new folder and rename it as expander, anywhere in your machine. Let's say in your `Desktop` folder. Open the newly created folder in any text editor. We recommend [Sublime Text](https://www.sublimetext.com) or [VS Code](https://code.visualstudio.com) for working with FTD. Open the folder and add two new files, `FASTN.ftd` and `index.ftd` to create the `fastn` package.

`FASTN.ftd`

It is a special file which keeps package configuration related data like - package name - package dependencies - sitemap, etc Import the special library, fastn
Import `fastn`
-- import: fastn
Lang:
ftd
Then, we create a new fastn package after giving line-space
Create a fastn package
-- fastn.package: <project-name>
Lang:
ftd

`index.ftd`

To print Hello World, we are using [`ftd.text`](/row/) section
Code
-- ftd.text: Hello World
Lang:
ftd
Create a local server and run the URL in the web-browser to see the text displayed. Make sure that the directory points to the expander folder you created.
Terminal command to create local server
fastn serve
Lang:
ftd
Using just one line code, we displayed the `Hello World`s. You have successfully completed the Part 1. Continue with the [part 2 now](/expander/basic-ui/).
