How we work
The honest answer in software usually starts with "it depends". That's why our color is graphite, not black: a gray, with pink running through it.
Itrium is Indonesian for yttrium, element 39: quiet, useful and out of sight, which is how we think good software should be.
Tell us what you're stuck on.
We'll tell you honestly whether we can help.
Write it in your own words: what you're trying to do, and where it's stuck. A screenshot or a link helps, and so does a deadline, if there is one.
