+# Overview
+
+This folder contains scripts for building the dependencies from source. The
static libraries from
+the build artifacts can be used to create self-contained shared object for
mxnet through static
+linking.
+
+# Settings
+
+The scripts use the following environment variables for setting behavior:
+
+`DEPS_PATH`: the location in which the libraries are downloaded, built, and
installed.
