This is a rough explanation on how to use this template.
Use the source editor, and paste the following:

{{Quote
|quote = 
|source = 
}}

Then fill in the quote field with the line being quoted without quote marks, and source for who was speaking and the source. Example:

{{Quote
|quote = It's okay... I'm going to be fine. '''I want skating to be win or lose.''' I want to become a medalist... an athlete [...] So watch me. I'm gonna do my best to look cool.
|source = [[Inori Yuitsuka|Inori]] to [[Nozomi Yuitsuka|Nozomi]] and [[Tsukasa Akeuraji|Tsukasa]], [[Chapter 4|Chapter 4]].
}}

which will produce the following:

"It's okay... I'm going to be fine. I want skating to be win or lose. I want to become a medalist... an athlete [...] so watch me. I'm gonna do my best to look cool."
