Appropedia, like all wikis, allows you to edit almost any page. It's super simple, just click the Edit button! If you make a mistake, don't worry! You can always revert any edit by clicking undo in the page history.

There are two main ways to edit pages: the visual editor and the source editor. The visual editor is generally easier and often enough. However, learning the source editor will give you finer control of the final output and is essential for more advanced editing.

Visual editor

Our Visual Editor is as straightforward as it gets. To dive in, simply hit the blue "Edit" button on the top right or the pencil icon on the top bar, then select "Edit." Make your changes, and when you're satisfied, click "Save Page" – that's it!

Source editor

For those craving more control and advanced editing options, we introduce the Source Editor. Click on "Edit Source" via the top right or the pencil icon, and you're in. The Source Editor lets you work with wikitext and even a bit of HTML, providing precision for your edits.

Advanced

Wikitext markup supports much more advanced formatting. However, try to keep it simple! Less markup generally makes your content easier to read, fix, improve, maintain, port and reuse by other people and software.

Definition lists are generally useless. However, colons : are often used for indenting text, especially in talk pages.

# Fruits
#* Apple
#* Banana
# Vegetables
#* Carrot
#* Spinach
  1. Fruits
    • Apple
    • Banana
  2. Vegetables

    • Spinach

Lists can be nested and combined. However, nesting more than once can be confusing to readers.

Horizontal lines are generally unnecessary and should be avoided.

Some HTML tags are allowed too, for example <div>, <span> and <table>.

Page history

How to access a page history

Ever made a change you regret? No worries! Every page has an edit history. You can undo changes or roll back a page to a previous version. To compare versions, use the "Difference to Current" and "Difference to Last" buttons for a side-by-side view.

To compare two versions of a page, use the "Difference to Current" and "Difference to Last" buttons. Diffs present changes in two columns, showcasing removed text on the left and added text on the right. The most recent version is displayed below for easy reference.

Appropedia is about collaboration, learning, and making information accessible. Dive in, make your mark, and together, let's build a richer knowledge base for everyone. Happy editing!
