What it does
HelloWorld covers the common software workflow without extra plugins. The interface stays close to the system defaults, so most users finish setup in one pass.

Grab the package that matches your platform, run the installer, and restart once. If the first launch is slow, that is usually the cache warming up.
Everyday tips
Keep automatic updates on, avoid stacking several tools that do the same job, and export your settings before a major upgrade.
