An h1 Header

Paragraphs are separated by a blank line.

2nd paragraph. Italic, bold, and monospace. Itemized lists look like:

• this one
• that one
• the other one

You can use 3 dashes—which is quite an elegant solution—to insert an em-dash.

Block quotes are written like so.

They can span multiple paragraphs, if you like.

An h2 Header

Here’s a numbered list:

1. first item
2. second item
3. third item

Here’s a link to a website, to a local doc, and to a section heading in the current doc. Here’s a footnote ¹.

Here’s a monospaced sample made by indenting a block of text with 4 spaces:

# Let me re-iterate ...
for i in 1 .. 10 { do-something(i) }

For writing actual code in markdown, you can use code-fences by surrounding with ```:

1
2
3

define foobar() {
    print "Welcome to flavor country!";
}

Here’s how it looks written in the actual markdown:

```
define foobar() {
    print "Welcome to flavor country!";
}
```

You can optionally mark the delimited block to syntax highlight it:

1
2
3
4
5
6
7

import time

# Quick, count to ten!
for i in range(10):
    # (but not *too* quick)
    time.sleep(0.5)
    print(i)

Here’s how it looks written in the actual markdown:

```python
import time

# Quick, count to ten!
for i in range(10):
    # (but not *too* quick)
    time.sleep(0.5)
    print(i)
```

An h3 header

Now a nested list:

1. First, get these ingredients:

   • carrots
   • celery
   • lentils

2. Boil some water.

3. Dump everything in the pot and follow this algorithm:

   1. find wooden spoon
   2. uncover pot
   3. stir
   4. cover pot
   5. balance wooden spoon precariously on pot handle
   6. wait 10 minutes
   7. goto first step (or shut off burner when done)

Tables can look like this:

A horizontal rule can be made with --- or *** on an empty line:

Inline math equations go in like so: $\omega = d\phi / dt$ . Display math should get its own line and be put in in double-dollarsigns within a katex-syntax code block:

```katex
$$I = \int \rho R^{2} dV$$
```

Alternatively the custom katex shortcode can be used instead of the code block:

{{<katex>}}
$$
\begin{pmatrix}
a & b \\
    c & d
    \end{pmatrix}
$$
{{</katex>}}

And note that you can backslash-escape any punctuation characters which you wish to be displayed literally, ex.: `foo`, *bar*, etc.
