+1.6 Nix - Autotools
+-------------------
+
+1. Install the development environment using the included expressions.
+
+    nix-env -i -f nix/env.nix         # build and install the environment
+    load-env-pioneer                  # load the environment
+
+2. Run ./bootstrap to generate your 'configure' file
+
+3. Run ./configure to configure the build.
+
+4. Run make to build everything
+
+Executing ./pioneer requires the development environment to be loaded,
+executing ./src/pioneer does not.
