Chose the “Type” of the article
As per wikipedia norms, any article you are proposing should fall into notable criteria & considered to be good for the wikipedia audience.
Wikipedia Notable Criteria: Notable article should be “worthy of notice” or “note” – that is, “remarkable” or “significant, interesting, or unusual enough to deserve attention or to be recorded”
In general, notability is an attempt to assess whether the topic has “gained sufficiently significant attention by the world at large and over a period of time” as evidenced by significant coverage in reliable secondary sources that are independent of the topic.
In short any topic you are proposing the article should have independent sources with enough details about the subject. A minimum of three external sources would do the job for you.

For the first time users, it is recommended that draft an article first, review it thoroughly before submissions.
