Installation of Moonlight on osmc (rpi 2)

i can’t seem to get moonlight installed on osmc (RPI 2)
i’m getting to the point of cloning , that succeeds.
trying to install via this google document

when i try to install via this command :

sudo chmod 755
sudo ./

i get error : osmc@mediacenter:~/moonlight-osmc$ sudo chmod 755
chmod: cannot access ‘’: No such file or directory

when i give command Dir
this is the output
osmc@mediacenter:~/moonlight-osmc$ dir
Makefile Vagrantfile debian moonlight-osmc

thank you.
ps i’m really new to all of this.
thanks !!
