This is a test post to check the functionality of the markdown rendering.

Heading 1

This is a paragraph under heading 1. It contains some text to demonstrate how paragraphs are rendered in markdown.

Rendering of bold text and italic text is also supported.

Lists can be created using either ordered or unordered formats:

• Unordered list item 1
• Unordered list item 2
• Unordered list item 3

1. Ordered list item 1
2. Ordered list item 2

Inline code can be added using backticks. For example, inline code is rendered as inline code.

# This is a code block in Python
def hello_world():
    print("Hello, world!")
    hello_world()

Links can be added as well. For example, OpenAI is a link to the OpenAI website.

Other elements like blockquotes and horizontal rules can also be included:

This is a blockquote. It is used to highlight a section of text.

KaTeX can be used for mathematical expressions. For example, the quadratic formula is given by:

$$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$
