Install instructions would be helpful.
Create folder NewThemes in ~/.config/sublime-text-2/Packages/NewThemes and dump the files from the repository in there. Then Preferences > Color Scheme > NewThemes > [choose]
Ah should have been better if via Package control
Cmd+Shift+P -> "Install..." -> [name of theme] -> [enter] -> done.
(editted) Ugh, apparently these are not in the package manger. Call me lazy but I'm not going to clone these on all four of the machines I use ST2 on. (The "ugh" seems unappreciative, that was more due to my incorrect assumption; don't mean to sound ungrateful, a couple of these look very excellent.)
@hayksaakian, Add
"color_scheme": "/home/victor/documents/Iceberg.tmTheme"Sorry, I have half a dozen color schemes in different packages that I switch between, a custom theme, several language plugins and more. It's enough work to re-install them through the package manager.
I could put them all in a folder and sync that across machines, but then they don't get auto-updated, and I'd have to use non-portable symlinks and would still have to manually update each of the likely 10 repos that I'd need to check regularly for updates.
May I ask why you have multiple color schemes? It seems like a pretty easy solution...
I use a portable version of Sublime 2 synced via Dropbox. It works pretty well. One copy of settings/themes/snippets.
