 ## How to contribute
 
-### I notice that the timetable is out of date.
+### I noticed that the timetable is out of date.
 
 Your contribution is welcome.
 
 ### What should I do?
 
-Edit CSVs under [resources](./resources) directory. The first column in each row means hour, and the others mean minutes. [#34](https://github.com/arosh/naist-bus-schedule/pull/34) is one of good examples.

 ### Why does the original author use such a ridiculous CSV format?
 
-Well... Nara Kotsu's latest system provides timetable data in PDF format, whereas the previous system provided them in HTML table format. In those days, HTML tables could be converted to machine-readable CSVs by formatting them in Excel or Google Spreadsheets. It was the easiest way to obtain machine-readable timetable data without complicated parsing programs. Since Nara Kotsu has upgraded the timetable system, the original author understands that this format is no longer useful.

 ### Should I include `data.json` in the PR?
 
-No. [#32](https://github.com/arosh/naist-bus-schedule/pull/34) includes `data.json` in the PR, but it is not needed anymore. GitHub Actions now automatically generate it.
