Should I fix the linting issues as well? The issue mentioned to let them be

[MaoShizhong]

For these, I can trust you to address any reasonable lint errors. Most should be fixable using the appropriate npm fix scripts, then if any obvious ones remain, you can manually fix those.

Feel free to ask any questions if you encounter any less clear lint errors.

Yes they were really easy fixes, but the linter still screams, it requires a section on lesson overview, can i work on it as well? Also there's an error which didn't make sense to me

• ruby_on_rails/mailers_advanced_topics/websockets_and_actioncable.md:320 TOP004/lesson-headings Required heading structure [Expected: h4 heading; Actual: h3 heading] https://github.com/TheOdinProject/curriculum/blob/main/markdownlint/docs/TOP004.md

It's a Knowledge Check section which is always written with h3, should i change it to h4 as per the linter?

Edit: I forgot to ask for another change i made, in the ruby_on_rails/mailers_advanced_topics/websockets_and_actioncable.md file, there were clashing headers with both having title as Connections (lines 63 and 104), I've made them a bit more descriptive and thus no clashing links and updated link in Knowledge Check as well.

[MaoShizhong]

We should leave the lesson overview errors alone - those require much more thought and won't be appropriate to resolve in this PR.

The error regarding ### Knowledge checks is because the heading is called Knowledge checks when it should be Knowledge check. De-pluralising checks will let the linter recognise it as the appropriate section, thus allowing the h3.

Regarding the two changed headings in the websockets lesson, what you have I believe should be fine. You will need to use sentence case though, so they should be changed to WebSocket connections and Client-server connections.

[mathdebate09]

I believe this should do it, also I moved the Conclusion up, right before Assignments section to adhere to the lesson structure.
