Naming conventions
all lowercase
All files & folder must us only lowercase
characters.
This includes extensions, like .jpg , .png ,
etc.
The only exceptions are README.md ,
LICENSE  & CNAME .
Nospaces
No spaces allowed anywhere in file & folder
names.
Be careful their are spaces hidden at the end,
after the extension.
Use a dash ( - ) to separate words.
Only letters, numbers & dashes
Use dashes ( - ) to separate words, e.g. super-
duper.html.
The only exception is the dot ( . ) before
extensions.
Underscores ( _ ) are also acceptable.
Good examples
index.html  — all lowercase.
t-rex.png  — no spaces, dashes
separating words.
dragon-1.jpg  — only letters, numbers &
dashes.
Bad examples
Index.html  — capital letters used.
t rex.png  — space in filename.
dragon’s egg.jpg  — apostrophe is a
non-standard character.
Be careful
dragon.JPG  — some programs like to use
uppercase extensions—change them to
lowercase.
full-site.tar.gz  — multiple
extensions are okay.
_archive  — underscores are fine, but try
to avoid them.
