# Dotfile Manager
2+
3+
This module attempts to detect the user's dotfile manager. Many [popular dotfile
4+
managers](https://dotfiles.github.io/utilities/) are supported.
5+
6+
## Supported dotfile managers
7+
8+
* [Bare git repository](https://www.atlassian.com/git/tutorials/dotfiles)
9+
* [chezmoi](https://chezmoi.io)
10+
* [YADM](https://yadm.io)
11+
12+
## Unsupported dotfile managers
13+
14+
### Dotbot
15+
16+
As [Dotbot](https://github.com/anishathalye/dotbot) is usually imported as a
17+
submodule inside the user's dotfile repository, there is no reliable way to
18+
detect if the user is using it.
19+
20+
### GNU Stow
21+
22+
[GNU Stow](https://www.gnu.org/software/stow/) has no standard configuration, so
23+
there is no reliable way to detect if the user is using it.
24+
25+
### Home manager
26+
27+
[Home manager](https://github.com/nix-community/home-manager) has no standard
28+
configuration.
29+
30+
### Mackup
31+
32+
[Mackup](https://github.com/lra/mackup) does not work on macOS since version 14
33+
(Sonoma, released September 2023).
34+
35+
### rcm
36+
37+
[rcm](https://thoughtbot.github.io/rcm/rcm.7.html) has no standard
38+
configuration.
