+pkgsrc
+======
+
+[pkgsrc](https://pkgsrc.org/) is a framework for building software for a
+variety of UNIX-like systems.
+
+It produces binary packages, which can be managed with tools such as
+[pkgin](http://pkgin.net/). pkgsrc is highly configurable, supporting
+building packages for an arbitrary installation prefix (the default is
+`/usr/pkg`), allowing multiple branches to coexist on one machine, a
+build options framework, and a compiler transformation framework, among
+other advanced features. Unprivileged use and installation is also supported.
+
+pkgsrc is the default package manager for [NetBSD](https://www.NetBSD.org/)
+and [SmartOS](https://www.tritondatacenter.com/smartos).
+It's also supported as a first-class option in [OmniOS CE](https://omniosce.org/)
+and [Oasis Linux](https://github.com/oasislinux/oasis).
+
+
+Bootstrapping
+-------------
+
+To use pkgsrc on operating systems other than NetBSD, you first need to
+bootstrap:
+
+	cd pkgsrc/bootstrap
+	./bootstrap
+
+Note that this is only for the most simple case, using pkgsrc's defaults.
+
+Please consult `bootstrap/README` and `bootstrap/README.OS` for detailed
+information about bootstrapping.
+
+Building packages
+-----------------
+
+	cd pkgsrc/category/package-name
+	$PREFIX/bin/bmake install
+
+Where `$PREFIX` is where you've chosen to install packages
+(typically `/usr/pkg`)
+
+On NetBSD, `bmake` is simply the built-in `make` tool.
+
+To build packages in bulk, tools such as `pkgtools/pbulk` and
+`pkgtools/pkg_comp` can be used.
