Hello, I'm Donner60. I noticed that you made a change to an article, Łódź, but you didn't provide a source. I’ve removed it for now, but if you’d like to include a citation to a reliable source and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. Donner60 (talk) 21:05, 26 June 2017 (UTC)

Proper citation needs to be placed in the article with the information specified in Wikipedia guidelines. The information you put on my talk page is a start but it is incomplete. Ultimately, you need to satisfy the guidelines, not just answer my question, in order to insert the information. Helpful information about editing Wikipedia can be found on various Wikipedia guideline and policy pages including: Help:Getting started; Wikipedia:Introduction; Wikipedia:Simplified ruleset; Wikipedia:Simplified Manual of Style; Wikipedia:Referencing for beginners; Wikipedia:Identifying reliable sources; Wikipedia:Citing sources; Help:Footnotes; Wikipedia:Verifiability; Wikipedia:No original research; Wikipedia:Neutral point of view; Wikipedia:Notability; Wikipedia:Biographies of living persons; Wikipedia:What Wikipedia is not; Wikipedia:Words to watch; Help:Introduction to talk pages; Wikipedia:Copyright Problems and Help:Contents. I hope you will understand that if there were no guidelines on verifiability and citation, people could insert anything about anybody. In fact, too much of that occurs and has to be caught and reverted as it is. Since I hope you will be a regular contributor to Wikipedia, I ask that you insert the citation in proper form after reviewing the guidelines on sources and citations. Thank you.
