# About FastAPI versions

**FastAPI** is already being used in production in many applications and systems. And the test coverage is kept at 100%. But its development is still moving quickly.

New features are added frequently, bugs are fixed regularly, and the code is still continuously improving.

Now let's say that you want to add a translation for the section [Features](features.md){.internal-link target=_blank}.

* Copy the file at:

```
docs/en/docs/features.md
```

* Paste it in exactly the same location but for the language you want to translate, e.g.:

```
docs/es/docs/features.md
```
