+# cpp-ethereum external dependencies
+
+**This is Work-in-Progress!**
+
+This directory hosts the external libraries that are needed to build cpp-ethereum.
+
+To automatically download, build, and link libraries, do
+```
+cd extdep; mkdir build; cd build; cmake ..; make
+```
+this will take some time.
+
+
+To check which libraries are already included, check `CMakeLists.txt`. Other libraries still need to be fetched via the system's package manager.
+
+Libraries will be installed in `cpp-ethereum/extdep/install/<platform-name>`
