to whatever you feel fit, your choices being public, private
unlisted, etc. After you do that then click on the icon above
the privacy selector.

you will likely find it here unless you chose to download it to a
different location. After selecting your video click okay to upload
it.

afther the video uploads and processes and you are happy with how it
looks simply click okay, which will bring you to the next page in which
you will be doing the next step.
Step Four:

labeled share, embed, and email. Click on the tab that says embed.
After clicking embed use CRTL+C to copy the code to your computers
clipboard, you will need this later.
Step Five:
Open the text editor of your choice (I am using Atom) and open a new
project/file. Make sure that you have html selected if you are using
a program that allows you to code different languages. Begin coding
the other parts of your website, if any.
Step 6:
After you have followed all other parts of the instructions you can
embed your video into your code. Do this by using the video element.
Paste the bit of text that was given to you in Step 4.
