# How-To
After downloading the project you can finally start creating your own program and use basalt. The first thing you want to use in your program is always:
```lua
local basalt = require("basalt")
```
It doesn't matter if you're using the source folder or the minified/packed version of basalt. Both can be found by using require("basalt") without .lua.
Also to really run basalt you should use
```lua
basalt.autoUpdate()
```
somewhere on the bottom of your program. basalt.autoUpdate() starts the event listener and the draw handler.
## Example
Here is a fully working example of how a program could look like:
```lua
local basalt = require("basalt") --> Load the basalt framework into the variable called "basalt"
--> Now we want to create a base frame, we call the variable "main" - by default everything you create is visible. (you don't need to use :show())
local main = basalt.createFrame()
local button = main:addButton() --> Here we add our first button
button:setPosition(4, 4) -- of course we want to change the default position of our button
button:setSize(16, 3) -- and the default size.
button:setText("Click me!") --> This method displays what the text of our button should look like
local function buttonClick() --> Let us create a function we want to call when the button gets clicked
basalt.debug("I got clicked!")
end
-- Now we just need to register the function to the buttons onClick event handlers, this is how we can achieve that:
button:onClick(buttonClick)
basalt.autoUpdate() -- As soon as we call basalt.autoUpdate, the event and draw handlers will listen to any incomming events (and draw if necessary)
```
If you're like us and strive for succinct and beautiful code, here is a cleaner implementation of the code above:
```lua
local basalt = require("basalt")
local main = basalt.createFrame()
local button = main --> Basalt returns an instance of the object on most methods, to make use of "call-chaining"
:addButton() --> This is an example of call chaining
:setPosition(4,4)
:setText("Click me!")
:onClick(
function()
basalt.debug("I got clicked!")
end)
basalt.autoUpdate()
```
