+# 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).
+
+Mandatory variables are `pkgname`, `pkgver`, `pkgrel`, and `arch`. `license` is not strictly necessary to build a package, but is recommended for any PKGBUILD shared with others, as [makepkg](makepkg.md) will produce a warning if not present.
+
+# Example
+PKGBUILD:
+```sh
+# Maintainer: User <mail>
+pkgname=NAME
+pkgver=VERSION
+pkgrel=1
+pkgdesc="DESCRIPTION"
+arch=('x86_64')
+url=URL
+license=("MIT")
+depends=("git")
+makedepends=("git")
+source=("FILE_NAME::FILE_URL")
+sha256sums=("SKIP")
+
+prepare() {
+
+}
+
+pkver() {
+
+}
+
+build() {
+	cd "$pkgname"
+	make
+}
+
+check() {
+
+}
+
+package() {
+	cd "$pkgname"
+	install -Dm755 ./app "$pkgdir/usr/bin/app"
+}
+```
