You don't need to read anything – anybody can edit; just go to an article and edit it. Be Bold, but please don't put silly stuff in – it will be removed very quickly, and will annoy people.
Ask for help. Talk to us live, or edit this page, put {{helpme}} and describe what help you need. Someone will reply very quickly – usually within a few minutes.
Play in your user area. For example, you can create your own testpage at User:Szczurekk/sandbox.
Edit existing articles, before you make your own. Look at some subjects that you know about, and see if you can make them a bit better. For example, Wikipedia:Cleanup#2009.
When you're ready, read about Your first article. It should be about something well-known, and it will need references.
Good luck with editing; please drop me a line some time on my own talk page.
I think it could be handy for you to browse through some of the links below so as to become more familiar with how Wikipedia works. If you need any help you can ask me on my talk page, or place {{helpme}} on your talk page and another Wikipedian will show up shortly. Please remember to sign your name on talk pages by clicking or by typing four tildes "~~~~"; this will automatically produce your name and the date. If you're already loving Wikipedia and plan on becoming a Wikipedian you might consider being "adopted" by a more experienced editor, just paste {{Adoptme}} into your userpage and you will gladly be adopted! You might also consider joining a WikiProject so as to collaborate with others in creating and improving articles of your interest. Click here for a directory of all the WikiProjects. Finally, please do your best to always fill in the edit summary field. Happy editing and once again, welcome to the fantastic world of Wikipedia!
I noticed you deleted all references in Valentyn Nalyvaichenko a few days ago.... PLEASE NEVER DO THAT AGAIN! References are an important part of Wikipedia (to prevent the forbidden Original research) and deleting them without an proper explanation might be a reason to block you from editing Wikipedia. Please also keep in mind What Wikipedia is not; it is not an indiscriminate collection of information nor a means of promotion; hence I just deleted some parts of Nalyvaichenko's Wikipedia article I felt that should not have been there. Also please be not shy to copy the lay-out of other English Wikipedia articles when editing... for consistency within Wikipedia and it will make article better readable for native English speakers (we edit English Wikipedia for them).
