## Description

> If grammar, enter problematic text here, otherwise delete this line.

```
The text states:
On the root directory of the everycheese project, there are two files: .env.sample.mac_or_linux .env.sample.windows

```
These files are not prefaced with a "." or hidden. The text should read:

`On the root directory of the everycheese project, there are two files: env.sample.mac_or_linux env.sample.windows
`
