+# PKGBUILD

 A `PKGBUILD` is a shell script containing the build information required by [Arch Linux](../../linux/Arch%20Linux.md) packages. [Arch Wiki](https://wiki.archlinux.org/title/PKGBUILD)
 
 Packages in [Arch Linux](../../linux/Arch%20Linux.md) are built using the [makepkg](makepkg.md) utility. When [makepkg](makepkg.md) is run, it searches for a PKGBUILD file in the current directory and follows the instructions therein to either compile or otherwise acquire the files to build a package archive (pkgname.pkg.tar.zst). The resulting package contains binary files and installation instructions, readily installable with [pacman](Pacman.md).
