+# This is an example showing a basic makefile that links in the IREE runtime by
+# way of the unified static library. It's recommended that IREE is added as a
+# subproject and cmake is used to add the dependencies (as in the CMakeLists.txt
+# in this directory) but when using other build systems this is easier to adapt.
+#
+# Configure the runtime:
+# cmake -GNinja -B ../iree-build-runtime/ . \
+# -DCMAKE_BUILD_TYPE=MinSizeRel \
+# -DIREE_SIZE_OPTIMIZED=ON
+# Build the runtime:
+# cmake --build ../iree-build-runtime/ --target iree_runtime_unified
+# Make this binary:
+# make custom-module-run-min RUNTIME_BUILD_DIR=../iree-build-runtime/
+#
+# Note that if IREE_SIZE_OPTIMIZED is used to build the runtime then the
+# -DNDEBUG and -DIREE_STATUS_MODE=0 are required on any binaries using it.
