+# Building Archlinux ARM packages
+Just like in Archlinux, you'll need `base-devel` and `git` before you can build anything.
+Get them now.
+```
+> sudo pacman -S base-devel git
+```
+
+## The PKGBUILDs repo
+Most Archlinux PKGBUILDs will actually just compile on Archlinux ARM without modification.
+Some of them, though, required modification.
+The modified PKGBUILDs are hosted in [a single git repo on github](https://github.com/archlinuxarm/PKGBUILDs).
+Clone this repo:
+```
+> git clone --depth=1 https://github.com/archlinuxarm/PKGBUILDs.git
+```
+Then search the repo for your package.
+Suppose you want to build `geoclue`.
+```
+> find PKGBUILDs -name geoclue
+> 
+```
+It's not there.
+That means the default Archlinux PKGBUILD must build just fine without modification.
+
+## Building an unmodified package
+
+The process is almost the same as in Archlinux, only the `-A` switch must be added to tell `makepkg` to ignore the architecture mismatch.
+```
+> git clone --depth=1 https://gitlab.archlinux.org/archlinux/packaging/packages/geoclue.git
+...
+> cd geoclue
+> makepkg -As
+```
+
+## Building a modified package
+
+What if you actually wanted to build `pacman`?
+```
+> find PKGBUILDs -name pacman
+PKGBUILDs/core/pacman
+> 
+```
+Oh! Looks like this one *has* been modified.
+Build this package instead of the Archlinux one, using the same procedure as before:
+```
+> cd PKGBUILDs/core/pacman
+> makepkg -As
+```
