+# Easy buck2 builds for Facebook projects
+
+This directory contains buck2 targets designed to simplify buck2 builds of
+Meta open source projects.
+
+The most notable target is `//build/buck2/install_deps`, which will attempt to
+discover and install necessary third party packages from apt / dnf / etc.
+See the "repos" directory for the currently supported platforms.
+
+## Deployment
+
+This directory is copied literally into a number of different Facebook open
+source repositories.  Any change made to code in this directory will be
+automatically be replicated by our open source tooling into all GitHub hosted
+repositories that use `buck2`.  Typically this directory is copied
+into the open source repositories as `build/buck2/`.
