+# `//third_party`
+
+Anything related to importing third party code and making it work with our monorepo lives here:
+
+- Vendored code.
+- Bazel rules for third party code.
+- Patches to thid party code.
+- Lock files and similar package manager definitions (whenever possible - things like `go.mod  have to live at the top level, and that's OK too).
+
+First-party code or build rules based *on* a third-party component should not live here.
