Open every article via the integrated bowser. From here you have direct access to Google search, in case you do not find what you are looking for in Wikipedia.

If you change the language of Wikipedia Wiki² tries to reload the recently viewed article in the new language. This works only if the title of the article in the new language is the same as in the former language.
If Wikipedia is providing a table of contents for an article you view it by tapping on the table of contents button. Tapping on an item in the list navigates to the corresponding part of the article.

Greyed entries in the table show keywords that you have entered before, but all articles with this keyword have been deleted.
Deleting articles means to remove them from the local storage. To remove the currently viewed article use the delete button as shown above.

You can enter new keywords after tapping on the new keyword button. The title of the currently visible article is shown on top. The recently used keyword is shown in the edit keyword field. Keywords already assigned to this article are shown in the "Assigned keywords" section. Every article has at least the "No keyword" tag.

To add a keyword to or remove it from the currently displayed article just tap on a keyword in the list. Tapping on "No keyword" removes all keywords from the current displayed article. You can also use the new keyword button as described here. If you tap on a keyword in the list this keyword is temporarily saved to the enter keyword field and stays there until you empty the field or type in another term. So if you view another article this is a convenient way to add the recently used keyword to this article.
If you use the forward/back buttons while the keyword list is visible this list stays visible. So you can assign existing keywords very quickly to other articles. Tapping on a non marked item adds the keyword to the article, tapping on a marked item removes it from the article.
You can also remove a keyword from an article by viewing the articles assigned to this keyword and swiping from right to left over the keyword.
Removing a keyword from an article does not delete the keyword from the database, it just removes the connection between the article and the keyword. How to delete a keyword completely see next section.
To rename a keyword tap on a keyword in the "Assigned keywords" section. The keyword is now moved to the edit field, here you can change the keyword. Tap on the + button to initiate the renaming.
To delete a keyword open the "Keywords" list or the "Add keywords" list and swipe from left to right over the keyword. This will remove the chosen keyword from every article it was assigned to and remove it from the keyword database. To delete all keywords at once please use the appropriate button in the settings screen.
The Settings screen gives you access to some maintenance functions as well as activating or deactivating warnings. Moreover you can define which informations are displayed in the tables. To change the font size use the slider in the settings section, tap three times on an article text or pull apart two fingers on your iPad screen
