# Entering Text

## Markdown​

Markdown (a readable syntax that gets converted to HTML) is used to write most of the text in ISLE lessons. If you haven't used Markdown before, don't worry! Markdown is light-weight, and much of what you want can be typed directly into the editor with little or no additional syntax. Below is a list of a few common text formatting tools; a nice summary of basic syntax can be found here and an extensive guide can also be found here.

Emphasis:

*sample* is rendered as sample

**sample** is rendered as sample

[Ada Lovelace](https://en.wikipedia.org/wiki/Ada_Lovelace) renders as Ada Lovelace (and you can click to follow the link)

Lists:

Markdown supports both ordered and unordered lists. An unordered list is made with asterisks (*) and hyphens (-) for the bullet points. For example,

* Item 1* Item 2    - sub-item

renders as

• Item 1
• Item 2
• sub-item

For an ordered list, we use numbers:

1. Item 12. Item 23. Item 3

becomes

1. Item 1
2. Item 2
3. Item 3

Tables:

To make tables in Markdown, vertical bars (|) are used to define columns and three or more hyphens (---) specify the column headings. For example,

| Book | Author || --- | --- || Harry Potter and the Goblet of Fire | J.K. Rowling || 1984 | George Orwell || Americanah | Chimamanda Ngozi Adichie |

is rendered similar to

BookAuthor
Harry Potter and the Goblet of FireJ.K. Rowling
1984George Orwell

## LaTeX​

LaTeX equations can be included by using the special TeX tag. Full details of the tag options can be found in the docs; the options you will use most are

• raw: the LaTeX code to render.
• displayMode: inline (false) or display mode (true). Defaults to false.
• numbered: whether to display an equation number of display mode equations. Defaults to false.

For example, <TeX raw="\frac{1}{\sqrt{2\pi}\sigma^2} e^{-\frac{1}{2\sigma^2}(x - \mu)^2}" displayMode={true} /> is rendered as

$\frac{1}{\sqrt{2\pi}\sigma^2} e^{-\frac{1}{2\sigma^2}(x - \mu)^2}$

Alternatively, inline LaTeX can be written with  (or ) and display-mode LaTeX equations can also be written with  (or ) rather than the TeX tag. For example, the same equation as above can be created by

$\frac{1}{\sqrt{2\pi}\sigma^2} e^{-\frac{1}{2\sigma^2}(x - \mu)^2}$

and

$$\frac{1}{\sqrt{2\pi}\sigma^2} e^{-\frac{1}{2\sigma^2}(x - \mu)^2}$$

## HTML​

In addition to custom ISLE tags like TeX, standard HTML tags are supported by ISLE. For example,

    <ul>         <li> visualization </li>        <li> data analysis </li>        <li> statistical modeling </li>    </ul>

is rendered as

• visualization
• data analysis
• statistical modeling
