+# 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 implemented in the BOLT libraries.
+
+## Which binary analyses are implemented?
+
+At the moment, no binary analyses are implemented.
+
+The goal is to make it easy using a plug-in framework to add your own analyses.
+
+## How to add your own binary analysis
+
+_TODO: this section needs to be written. Ideally, we should have a simple
+"example" or "template" analysis that can be the starting point for implementing
+custom analyses_
