Wikipedia articles usually start humbly, developing and improving gradually over time — even when they are largely written by just one or a few contributors.
Typically, you start by making a stub, just a paragraph or two that serves to identify the topic, with enough sourcing to assure readers that it ought to have its own article. As you expand the article — perhaps nominating it for DYK along the way — you divide it into sections on different aspects of the topic. Once the article is relatively comprehensive — at least touching on the major aspects of the topic — should get some advice from others. After incorporating that feedback, if you think it meets the Good article criteria, you nominate it for Good article status, working with the reviewer(s) to fix any major shortcomings. After more polish and more research to cover every significant aspect of the topic, you can attempt the Featured article process. If, by the end, article meets the more stringent Featured article criteria, then the article will be eligible to have its day on Wikipedia's Main Page, where it draws the attention of tens of thousands of readers.
