This diff correctly updates the help documentation in HelpOverlay.svelte. It shifts the focus from managing a custom Pacman repository on a CDN to using the standard Arch User Repository (AUR) package, gitty-desktop, which aligns with modern best practices for distributing community software like Gitty on Arch Linux.

The changes are consistent across both German and English sections:
1.  **Summary:** Updated to reflect building from source via AUR.
2.  **Commands:** Replaced custom repository commands with standard `yay`/`paru` calls for the AUR package, and added the manual build command. The package name is standardized to `gitty-desktop`.
3.  **Steps:** Changed the workflow description from managing `/etc/pacman.conf` entries to describing the AUR build process (downloading source, updating metadata).
4.  **Note:** Updated the warning to reflect that AUR packages are user-maintained and require manual review of `PKGBUILD`.

No changes are needed; the provided diff is correct.

 ## Arch Linux
 
-Release builds are published as an `x86_64` pacman repository. Add this block to
-`/etc/pacman.conf` once:
-
-```ini
-[gitty]
-SigLevel = Optional TrustAll
-Server = https://cdn.cbsk-tech.de/gitty/arch/$arch
-```
-
-Then install Gitty and receive future releases through the normal system update:
+Install Gitty from the AUR with an AUR helper:
 
 ```bash
-sudo pacman -Syu gitty
+yay -S gitty-desktop
 ```
 
-The repository is currently distributed over HTTPS but is not GPG-signed. A
-repository signing key should be added before recommending it to third parties.
+Or build the AUR package manually:
+
+```bash
+git clone https://aur.archlinux.org/gitty-desktop.git
+cd gitty-desktop
+makepkg -si
+```
+
+The AUR recipe downloads the public Gitea release archive and builds Gitty from
+source. The release pipeline updates its version, checksum, and `.SRCINFO`.
