# How to use Markdown in Pluto

If a Pluto cell starts with `md"` and ends with `"`, it is a markdown cell!

!!! info "Julia cells and Markdown cells"
	Some notebook environments have different **cell types**: a *code* cell and a *Markdown* cell.

	In Pluto, there is **only one cell type**: a Julia cell. But you can use the Julia string macro `md"` to write Markdown inside of Julia! 🤯

Instead of typing `md"` by hand, you can press **`Ctrl + M`** (or **`Cmd + M`** on Mac) to do it automatically.

👉 Try it yourself! In the cell below, press **`Ctrl/Cmd + M`**, type a message, and run the cell.

Text blocks are often describing code, so it's important that we can write code neatly!

You can use `ticks` when you want to talk about variables or expressions.
"""

md"""
For longer pieces of code, you can use three ticks:

```
x = 1
```

If you're writing code in a specific language, you can also specify it to get nice formatting:

```julia
function square(x)
	x^2
end
```

Neat!

If you want to include an image from the web, it looks a lot like adding a a link. Adding a `!` at the start means that we want to *show* the image instead of linking to it.

![julia logo](https://julialang.org/assets/infra/logo.svg)

For images, the text between the `[]` is used as *alt text*: a text description that can be used when the image can't be shown. This is useful for people with impaired vision, but it's also useful if the link doesn't work.

What if you want to add an image that isn't on the internet? You can also link to your own filesystem:

![cute picture of my dog](C:/Users/Luka/Pictures/Hannes_playing_in_the_snow.jpg)

Oops, you probably can't see that one! That's the trouble with linking to files: it doesn't always work. There are ways around that, but if you're new to all this, linking to online images is the way to go. We recommend uploading your image to the web (with `imgur.com` for example) to get a URL.

## Dynamic content

Writing some text is nice, what's really neat is if the text can **respond to code**. A simple way to do this is with an `if`/`else` block. Here we make a statement based on the value of `x`:

👉 Try changing the value of `x` to `-5`, and watch how the text changes.

### Interpolating values

You can also use **`$`** (the dollar sign) to include expressions in your text. 

For example, your text can include the value of a variable:
"""

md"""
The value of `x` is $(x), which is $(x > 100 ? "a lot!" : "not very high.")
