Error when import strategy files

[Looser]

Hi,

Newbie under Gekko but accustomed to mt4, I receive an error when I try to use an external strategy download from https://github.com/xFFFFF/Gekko-Strategies
All strategy download have the same error : 
Expected "[", Comment, DoubleQuote, Newline, Whitespace, [a-z], [A-Z], [0-9], "-", "_" or end of input but "<" found.

Any idea?

Thanks
