yaml parse exception

[remipoupard]

Hi, I'm a 18 info student and we have to answer our homework using Markdown.
While trying to convert it in pdf with Pandoc, I got this error

$pandoc -f markdown -t pdf Configuration.md
YAML parse exception at line 3, column 1,
while scanning an alias:
did not find expected alphabetic or numeric character

Here's my markdown, can you help me please I don't understand this error.

Configuration.md

From the user guide on Horizontal rules:

We strongly recommend that horizontal rules be separated from surrounding text by blank lines. If a horizontal rule is not followed by a blank line, pandoc may try to interpret the lines that follow as a YAML metadata block or a table.

This is what happens on lines 69-70 of your file. So try adding a blank line after the ---.
Or reconsider your use of the horizontal rules.

(I'd have other recommendations for your use of markdown in this file, but it's beyond your question.)
