+
+Build Rack plugins for Mac, Windows, and Linux with a single command on any Linux distro.
+Coming soon: Use Docker to build on Mac, Windows, or Linux.
+
+
+## Building
+
+Clone this repository in a path without spaces, or the Makefile will break.
+
+Obtain `MacOSX10.13.sdk.tar.bz2` using the method at https://github.com/tpoechtrager/osxcross#packaging-the-sdk, and place it in the root of this repository.
+This must be done on a computer with Mac 10.13.
+
+Build toolchains for each platform.
+```
+make toolchain-linux
+make toolchain-windows
+make toolchain-mac
+```
+Each toolchain will take around an hour to build, requiring network access and about 15 GB free disk space total.
+
+Download the latest Rack SDK.
+```
+make rack-sdk
+```
+
+## Building plugins
+
+Build plugin package for all platforms.
+```
+m plugin-build PLUGIN_DIR=...
+```
+
+This places packages in `plugin-build/`.
