Have a go!
editYou have pretty much written the sort of text that needs to go in the article. The only significant task left is to find the supporting evidence (since we are not allowed to give personal opinions). It may be that one of the citations you need is at simple:Bletchley Park? ("Simple" is simple English wikipedia for EFL learners and for kids). When you've done it, invite comment. People will help you with doing the mark-up though you might like to read wp:citing sources. Don't worry if you get it wrong, we all started crawling and falling over. Most [though not all] of us have not forgotten that! --John Maynard Friedman (talk) 21:58, 21 November 2018 (UTC)
