+# BOLT-based binary analysis
+
+As part of post-link-time optimizing, BOLT needs to perform a range of analyses
+on binaries such as recontructing control flow graphs, and more.
+
+The `llvm-bolt-binary-analysis` tool enables running requested binary analyses
+on binaries, and generating reports. It does this by building on top of the
+analyses implementing in the BOLT libraries.
