Creating new article. When creating new article from scratch, you see an empty field for entering text (similar to text editing software like Word).
When creating an article, one can use search function to look up definition in the dictionary or translating between languages. In this case the topic of «Такмаклар» (Chastushka folk songs) stands for «Частушки» in Russian. The author thus can, for example, dedicate a segment to a comparative analysis of two terms.
When formatting the article, it's text should be linked to Wikimedia portal resources (on Wikipedia or other Wikimedia projects — internal/interwiki links) or external Internet resources внешние (external links), which have content of possible value to the reader of the article. When developing materials, showing references and used sources is a must (verifiability). Other things being equal, sources independent from the topic in question and under free license, webportals of respected organizations, ISBN-numbered materials, and other similarly (reliable sources) are to be given priority.
Note: Wikimedia project users can ask questions at respective article's Talk page («Бәхәс») or at one of thematic forums.
