3) attach the piefiller to the part of your application that you want to monitor, it can be whatever but I suggest calling it in love.update or love.draw as this is what piefiller is all about.
```lua
function love.update()
Pie:attach()
-- do something
Pie:dettach()
end
```
4) draw the output in your draw function and give event hooks for your pie.
```lua
function love.draw()
Pie:draw()
end
function love.keypressed(...)
Pie:keypressed(...)
end
function love.mousepressed(...)
Pie:mousepressed(...)
end
```
5) When you get sufficient output press the "P" key to output to file.
#Keys
r = resets the pie
up = decreases depth
down = increases depth
, = decreases step size
. = increases step size
s = shortens the names displayed
c = hides/shows hidden processes
p = saves to file called "Profile" and opens directory for you
# Additional notes
The best depth to search for is 2 and 3.
When used in large applications the output is difficult to read, however printing to file resolves this issue.
