https://github.com/AppFlowy-IO/AppFlowy-Docs/blob/cb1d8a02d240749c85bb75e37c96b9903393f235/essential-documentation/contribute-to-appflowy/architecture/backend/event.md?plain=1#L155

### Awkward / Redundant Structure:
***Inaccurate:***
"to `enable` the build.rs `will only run`"
***Accurate:***
"to `ensure` that build.rs `only runs`"
(or more simply: "so that build.rs only runs")

### Tense Consistency:
***Inaccurate:***
"if the files `were` changed"
***Accurate:***
"if the files `have` changed"
(or "if the files change" for general present meaning)
