+# Common Docker instructions to install "crosstool-ng" and build a full
+# cross-compiler suite from a crosstool-ng configuration, CROSSTOOL_CONFIG.
+#
+# This import complements the "dockcross/base" image, adding:
+# - "ct-ng", a cross-compiler building utilty.
+# - A cross-compiler suite configured in "crosstool-ng.config".
+#
+# The generated cross-compiler will have a CROSS_ROOT of:
+#   ${XCC_PREFIX}/${CROSS_TRIPLE}
+#
+# A given platform will need to supply the appropriate "crosstool-ng.config" to
+# generate its cross-compiler. This can be built using "ct-ng menuconfig" to
+# generate a configuration.
+
+# Install Debian packages required for `ct-ng`.
