Markdown is a set of simple conventions for formatting text in R Markdown (RMD) files.

It makes it easy to create professional documents with minimal effort.

Here are the basic formatting rules for Markdown:

1 Headers

# Heading One (h1)

## Heading Two (h2)

### Heading Three (h3)

#### Heading Four (h4)

##### Heading Five (h5)

###### Heading Six (h6)


2 Text Style

With Markdown, it is possible to emphasize words by making them *italicized*, using *astericks* or _underscores_, or making them **bold**, using **double astericks** or __double underscores__. 

Of course, you can combine those two formats, with both _**bold and italicized**_ text, using any combination of the above syntax. 

You can also add a strikethrough to text using a ~~double tilde~~.

5 Images

Insert images in a similar way, but add an exclamation mark in front of square brackets [ ], and the image file name goes in the parentheses ( ).

![alt_text_here](image_file.png)

The alt text appears when the image cannot be located, or is read by devices for the blind when the mouse hovers over the image. It

It is common practice to place all of the image files in an “assets” or “images” folder to keep your directory tidy. You can reference files inside a folder using the folder name and the forward slash:

![a flower](images/flower.jpg)
a flower

a flower


Or you can link directly to an image online using the URL address of the image:

![](https://cdn-image.travelandleisure.com/sites/default/files/styles/1600x1000/public/1507062474/hotel-everest-namche-nepal-mountain-lodge-MOUNTAIN1017.jpg)


If you want to include images you need to add the image file to the images folder in this repository. Web-friendly formats like PNG, JPEG, or GIF are preferred.

You can just drag and drop the images into the folder, and GitHub will automatically initiate an upload option. After the upload progress bar is complete, click on the green “Commit changes” icon to complete the upload process.

You will then reference images in text using markdown syntax (see the Markddown Guide above for more details):

If you would like to post a video:

  1. Upload the video to a video platform like YouTube, and insert an iframe of the video into your document.
  2. In YouTube, you will find iframes by clicking on the Share option, and the “Embed” icon.
