+### Blamer
+If you have Go installed, a command-line tool is available to search through
+git history and do text searches on the full patch text and the commit
+message. To install blamer run:
+
+ go get go.skia.org/infra/blamer/go/blamer
+
+Then run blamer from within a Skia checkout. For example, to search if the
+string "SkDevice" has appeared in the last 10 commits:
+
+ $ $GOPATH/bin/blamer --match SkDevice --num 10
