June 19 2017 Update: SALTs is also in the new Exodus repo, so 1 install guide = 2 great Kodi addons update on your system! The current version is v2.0.196.
June 11 2017 Update. tknorris no longer the developer of SALTS. The new developer is k3l3vra and this addon is now in new repository.
Uninstall the Stream All The Sources addon you currently have installed and install the latest one. The current version is v2.0.195.
Direct install SALTS repository from here.
Installation of SALTS addon is very easy via repository like Superrepo. However, you are also install a lot of unwanted music, video and program addons at the same time. The installed addons are not the latest most of the time. You will have to wait for auto update triggered by Kodi.
If you like to have the latest version on SALTS on first installation, as well as keep your files to minimum, then you should install addons direct from it parent repository. Here is how can you do it on SALTS.
My example is based on SALTS 2.0.53. The current version is SALTS 2.0.105 as of Oct 20 2016.
