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

In simple words: py-fsrs is a tool made for people who build software, for memorising things with question-and-answer cards. It is completely free and open source — its code is public on GitHub, where 520 people have bookmarked it as worth using.

Step by step — how you would actually use it

1. An honest note first: py-fsrs 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 memorising things with question-and-answer cards 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: You learn new words a few cards at a time with a tool like this — a little daily practice that actually stays in memory.
