🧭 What Does across Actually Do? — A Plain-English Guide

In simple words: across is a tool made for people who build software, for keeping safe backup copies of important files. It is completely free and open source — its code is public on GitHub, where 5,375 people have bookmarked it as worth using.

Step by step — how you would actually use it

1. An honest note first: across is made for programmers and system administrators, not for everyday clicking.
2. They install it on their computer or server, following its README.
3. They connect it to their project or system, usually with a few settings or commands.
4. From then on, it helps them with keeping safe backup copies of important files as part of their daily technical work.
5. Everyday users meet this tool only indirectly — inside the apps and websites it helps to build and keep running.

💡 A real-life example: A family keeps its photos backed up and private with tools like this, instead of trusting a big company's cloud with everything.
