He is using Libreelec though and that works out of the box with samba shares, you just need to add source and either point it at your samba share if it shows automatically , or type in your ip/system name of the samba share and add it as a source. At least that is how i do it, i have a kodi addon folder on my windows pc that is shared on the network, i then pointed my libreelec to that folder so i can instal addons over the network.
