 # Main method
 The related scripts and files around `install.sh` belongs to "main method", which is developed and maintained mainly by clsty.

 ## Folder Structrue
 Main script: `install.sh`
 - The script keeps its "data" part under `./scriptdata/`. Some files are also shared by other scripts.
 - When the script build something from source, they're stored under `./cache/`. Of course, `./cache` is listed on `.gitignore`.

+### Old Dependency Installation Method
 The old deps install method mainly involves `./scriptdata/dependencies.conf` (which is empty now). It's not used anymore but I keep the relevant part just in case, e.g. the new install method breaks in future.
 
 There is also a `checkdeps.sh`:
   - It checks the existence of pkgs listed in `./scriptdata/dependencies.conf`.
   - It somehow fixes [the problem caused by yay](https://github.com/end-4/dots-hyprland/discussions/204).

 Local PKGBUILDs under `./arch-packages/` are used to install dependencies.

 Why is this awesome?
 - It makes it possible to control version since some packages may involve breaking changes from time to time.

 The PKGBUILDs contains two forms of dependencies:
 - Package name written in dependencies, like a "meta" package.
 - Normal PKGBUILD content to build dependencies, e.g. AGS, which is often for version controlling.

+:::note[background]
+This script is optional since the `install.sh` is already capable for upgrading, while keeping some customed files unchanged.
