Thank you for your your contributions to ArchWiki. Please make sure to include an edit summary with every edit, even minor ones, as this is helpful when browsing an article's history. I'd suggest you to go to Special:Preferences and check "Prompt me when entering a blank edit summary".
I will comply with everything you ask for. Just let me know how to do. I turned on the "warn me". Maybe next time it also shows where to add such summary. What in detail do you expect to be added? I mean: this page has been created by me. I pressed save like a hundred times. Shall I add a summary each time? That may be time consuming and probably won't add any value...
Got it. I read the help ;-) Thanks for the link.
