+## Guiding Principles
+
+instalee closely follows the UNIX philosophy with directory structures and files as configuration.
+The goal is to be as generic as possible to accomodate any kind of setup.
+
+However, it should be efficient while generic,
+preventing repetition at every level.

+- Software and Provider are derived from Function and Handler but can change depending on the system
+- Idea: `providers/<provider>/<handler>[_<ext>]` rather than `handlers/<handler>/install[_<ext>]`
+  + but then one might duplicate the handler script if one provider handles multiple equally,
+    such as `yay` for arch and aur
+  + how about `providers/<handler>/<provider>[_<ext>]`? 
+    Same duplication issue, now spread out...
+  + underscore extension might be superfluous through that, since `ext` was somewhat a proxy for a proper `provider` configuraion
