+Using Valgrind in Sapphire at Nest Labs
+=======================================
+
+Since nobody at Nest is using Valgrind regularly, using valgrind will always be
+batteries-not-included. There are some breadcrumbs left by the ancients:
+
+    https://wiki.nestlabs.com/display/NEST/Running+Valgrind+on+sapphire+device
+
+    sapphire/production/sw/nestlabs/tools/valgrind-scripts/Makefile
+    https://nest-internal.googlesource.com/platform/sapphire/+/master/production/sw/nestlabs/tools/valgrind-scripts/Makefile
+
+However, they are already out-of-date. However, these links are provided in case
+you find them helpful.
+
+In order to use valgrind effectively, you'll probably want to follow the
+following steps:
+
+   [ ] Change your product makefile config (e.g. flintstone.mak):
+       [ ] Enable BUILD_FEATURE_VALGRIND
+       [ ] Disable BUILD_FEATURE_FLINTSTONE_CONSOLE (it steals
+           the console from you)
+       [ ] Disable BUILD_FEATURE_AUTOLOG (it steals the console
+           from you)
+   [ ] Disable GCC library static linking (as of this writing,
+       you can do it by switching from the 2.0.1c toolchain
+       to the 2.0.1b toolchain). You need to do this so you'll
+       have enough room on the firmware image.
+   [ ] In order to use valgrind you'll need to have the debug
+       symbols for ld.so installed on the device. If you're using
+       the 2.0.1b toolchain, this will happen for you automatically.
+       For other Poky-based toolchains, you'll have to install them
+       on the device yourself:
+
+           $ scp /opt/poky/<ver>/sysroots/<mach>/lib/.debug/ld-2.22.so \
+	        root@192.168.33.2:/lib/.debug/
