Mirrors
[edit] Thanks for contributing to the article Bivalent (engine). However, one of Wikipedia's core policies is that material must be verifiable and attributed to reliable sources. You have recently used citations which copied, or mirrored, material from Wikipedia. This leads to a circular reference and is not acceptable. Most mirrors are clearly labeled as such, but some are in violation of our license and do not provide the correct attribution. Please help by adding alternate sources to the article you edited! If you need any help or clarification, you can look at Help:Contents/Editing Wikipedia or ask at Wikipedia:New contributors' help page, or just ask me. Thank you. Kuru (talk) 23:30, 18 June 2022 (UTC)
