I'm so lost. I have tried the search button, but all the answers were so confusing because I need more of a background to it. Oh and can you upload txt files. Like say if you were to make a page in notepad...how do you put that on your page? hahaha.

Well if your using ftp , you upload it through ftp.
If you have your pagebuilder site then just
upload it through the little uploading page.

If your try to make your website page in notepad.
Then you just upload it through ftp
and change the extension from .txt to .htm or .html or .php.

Use .html first. .php isn't supported by some hosts and if you don't know what you're doing, .php can screw up your site.
And, if you're coding in Notepad, backspace when you're saving otherwise the file will still be just a text file.
