Paragraph

Links

Have the text within square braces [ ], followed by the URL in round braces ( ).

Lists

Ordered lists

Use numbering for ordered lists.

2. Item 2
3. Item 3

Unordered Lists

Use - or + or * for unordered lists.

Code

To represent code or text that you don't want markdown syntax to decipher:

Enclose them with a single backtick (`) for single line content, which would show up as:

Single line code enclosed within single backtick

Enclose them with triple backticks (```) for multi line content

def function():
    print("Hello World!")

Tables

Syntax for table is

| Column 1   | Column 2 | Column 3 |
| ---------- | -------- | -------- |
| Row 1 Text | Text     | Random   |
| Row 2 Text | Text     | Random   |
