+### How do I update/add external libraries?
+
+If the library you want to update is in Maven Central or JCenter (or has its own
+Maven repo), add it or update its version in `build.gradle`. If the library is
+in the `libs/` directory, you can update it using a subtree merge by doing the
+following (using `minidns` as an example):
+
+    git remote add minidns https://github.com/rtreffer/minidns.git
+		git fetch minidns
+		git merge -s subtree minidns master
+
+To add a new dependency to the `libs/` directory (replacing "name", "branch" and
+"url" as necessary):
+
+    git remote add name url
+		git merge -s ours --no-commit name/branch
+		git read-tree --prefix=libs/name -u name/branch
+		git commit -m "Subtree merged in name"
