-Currently:
-- `install.sh` `checkdeps.sh` `setup.sh` only work for Arch(-based) distros.
-- `update-ags.sh` works for common distros, but user must figure out deps for AGS themselves (at least not easy for openSUSE, see [end-4#275](https://github.com/end-4/dots-hyprland/discussions/275) and [Aylur#313](https://github.com/Aylur/ags/discussions/313)).

-# Structrue
+# 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.
 
-Other scripts:
-- `update-ags.sh`
-  - The script uses the `install-ags` function from `./scriptdata/installers`.
-  - If executed, it installs AGS without confirm.
-- `checkdeps.sh`
-  - Check the existence of pkgs listed in `./scriptdata/dependencies.conf`.
+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).
-- `uninstall.sh`
-  - Deprecated. Unrecommended to use because its behavior may be destructive.
-  - If executed, it tries to revert all changes from `install.sh`, whether the change is or is not really caused by `install.sh`.
 
-Online script: `setup.sh`
+## Current Dependency Installation
+Local PKGBUILDs under `./arch-packages/` are used to install dependencies. It enables a workable `uninstall.sh` script.
+
+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.
+## Configuration Files Sync
+Mainly use rsync.
+
+# Online script
+`setup.sh`:
 - Stored in the repo of dots-hyprland-wiki to be served by the doc site directly.
 - When executed, it downloads the dots-hyprland repo and then executes the `install.sh`.
 # Idempotent
-The scripts (`install.sh` `update-ags.sh` `checkdeps.sh` `setup.sh`) are and should be **idempotent**, i.e. capable for running multiple times.

 This is useful for debugging and a resumable installation, and also provide updating function somehow.
