+This is intended to document how to build a release version of SFZQ.  For a
+release, one wants to create something that will run under as many different
+distros as possible.  That means using older versions of GLIBC and GCC.  The
+Surge XT synthesizer project has helpfully shared how they do that, using
+Docker; this is a modification of their work.
+
+How to do it:
+
+```sh
+./make-image
+./enter
+```
+
+The `make-image` only needs to be done once.  The `enter` fires up a container
+and drops you into a shell there.  Once inside, you should be able to do this:
+
+```sh
+cd persistent/sfzq
+make
+```
+
+Assuming all goes well, you can then exit the container, and the shippable
+plugin will be at "persistent/sfzq/sfzq.clap".
