Crowdsourcing
Wikipedia has many editors, each editor is usually subscribed to change notifications of the article they created/edited during their Wikipedia activity life span. When you make an edit, one of the editors reviews it and if it's spam he will revert the change to the article previous state.
Wikipedia relies on people to filter out the spam, you can do this too by going to the history tab.
1- Create the page in the new language
On the page you want to translate, change the language prefix (xxx.wikipedia.org
) to your language's prefix. This will bring you to a blank page and Wikipedia will ask you if you want to edit it. If you don't know your language's prefix, find it by going to www.wikipedia.org where all the languages are listed.
For example, if you want to translate the article en.wikipedia.org/wiki/Stack_Exchange_Network
to Japanese, go to ja.wikipedia.org/wiki/Stack_Exchange_Network
and find the link to edit the page.
However, it can most often be that the translation of the article has also a translated name. For example, if you translate the page square into french, you would not create the page fr.wikipedia.org/wiki/square
but the page https://fr.wikipedia.org/wiki/Carr%C3%A9
2- Link the new created page to the other languages
a. Once you have created the article in your language, let's say fr.wikipedia.org/wiki/Carré
go to the page in an old language, e.g., english en.wikipedio.org/Square
and there click on Edit Links
under the languages names

b. Now, a site opens with a frame called just wikipedia
and Edit
on top of the languages: click again on this "Edit" link.

c. Finally you end up in the linking form. There you have to fill the fields Site ID
with the language wiki id, for example, in our case is frwiki
for the french wikipedia page. And fill the field Sitelink
just with the name (not the full address!) of your new translated page, in our case, with Carré
.

d. Click Set the sitelink
and your translated page should be accessible from the main page of the other languages in the languages links.

All you have to do is click the Edit button at the top of an article's page. In the page that you see afterward, you can make your changes and then save them.
You won't be able to edit some Wikipedia articles, however - instead of an Edit button, such protected articles will show a View Source button.
Also, when editing an article, it is recommended that you click
Preview
before you save your changes. This way, you can make sure that your changes were made as you intended.For editing, you don't even have to log in. However, if you don't log in, there are a few disadvantages:
Before editing, I recommend you read some of Wikipedia's guidelines, so that you understand how Wikipedia works and how articles are supposed to be.
One last thing - it may be hard to get used to how formatting works on Wikipedia. That's why they wrote a cheatsheet for editors.
