-My NixOS configuration
-----------------------
+# My NixOS configuration
 
-My configurations for NixOS using flakes. For now only my desktop computer is
-configured with this system.
+My machines and dotfiles management using Nix / NixOS.
 
-## Install
+## Installation
+
+Project contains a devshell installing all needed and  a 
+[Taskfile](https://Taskfile.dev) is available to help manage elements whether
+Home-Manager or NixOS configuration.
 
 ```
-doas nixos-rebuild switch --flake ".#mrmeeseeks"
+task --list-all
+task: Available tasks for this project:
+* check:flake:               Check flake
+* check:sh:                  Check SH files, will call all check:sh:* tasks
+* check:sh:shellcheck:       Pass Shellcheck on all *.sh files
+* check:sh:shfmt:            Pass shfmt in check mode on all sh files
+* check:typos:               Check typos in all files
+* home:*:*:                  Manage Home-Manager configuration, use home:verb:target format
+* home:gc:                   Garbage collect Home-Manager packages
+* home:list-gen:             List Home-Manager generations
+* host:*:switch:             Switch both Home-Manager and NixOS generations
+* host:*:update:             Update package version then build NixOS and Home-Manager
+* nixos:*:*:                 Manage NixOS build, use nixos:verb:target format
+* nixos:gc:                  Garbage collect NixOS

-## Update the flakes.lock
-
-```
-nix flake update
-doas nixos-rebuild switch --flake ".#mrmeeseeks"
-```
-
-## Update manual packages from github
-
-Some modules use `fetchFromGithub` who need *SHA-256* hash to meet
-reproductibility. Theses hashed can be obtain with `nix-prefetch-github`:
+Managing *NixOS* installation, you can use all `nixos:*` targets for example:
 
 ```shell
-$ nix-shell -p nix-prefetch-github
-$ nix-prefetch-ghithub --rev v1.22.0 sindresorhus pure
-{
-    "owner": "sindresorhus",
-    "repo": "pure",
-    "rev": "87e6f5dd4c793f6d980532205aaefe196780606f",
-    "sha256": "TR4CyBZ+KoZRs9XDmWE5lJuUXXU1J8E2Z63nt+FS+5w="
-}
+# build mrmeeseeks nixos:
+task nixos:build:mrmeeseeks
+
+# build/switch nixos installation for mrmeeseeks
+task nixos:switch:mrmeeseeks
+
+# build ephase home configuration for mrmeeseeks:
+task home:build:mrmeeseeks
+
+# build / switch ephase home configuration for mrmeeseeks
 ```
 
-In this example we have obtained the hash for the specific 1.22.0 version.
+## Update nixpkgs version
+
+Update packages repositories version can be done with `host:<hostname>:update`:
+
+```
+task host:mrmeeseeks:update
+```
+
+`flake.lock` file will be updated then both NixOS and Home-Manager will be
+rebuilt. Note than new generation will not be activated, to do so you need to:
+
+```
+task host:mrmeeseeks:switch
+```
