 ## folder structure
 
-### certificates
+### [certificates](certificates)
 
 Should only contain public certificates. Though i am thinking about making even
 them a secret with the future (r)age-nix setup
 
-### dev_shells
+### [dev_shells](dev_shells)
 
 Each dev-shell should have it's file or folder, even the default one
 
-### experiments
+### [experiments](experiments)
 
 The feel free folder, but don't go overboard, it should be temporary or interim stuff.
 
-### hosts
+### [hosts](hosts)
 
 Each host should have a folder with a default.nix in it. This file should import
 from system_profiles and can import specific things, but at some point just
 create a new system_profile. Especially when multiple hosts share imports
 
-### lib
+### [lib](lib)
 
 nix functions, that can be used around this repo. Please not on the outside
 
-### modules
+### [modules](modules)
 
 Most functionality is in here atm, not well defined yet.
 But basically just NixOS options
 
-### overlays
+### [overlays](overlays)
 
 nixpkgs overlay, right now only used for nixos-unstable
 
-### system_profiles
+### [system_profiles](system_profiles)
 
 This whole folder is for the most part just a system to clean up importing
