+The major part of the implementation of the API is in [`api.cpp`](src/api.cpp).
+To use the API as it stands, you need to include the header [`api.h`](src/api.h)
 in your program, and link against the resultant shared-object from the CProver
 build process (`libcprover-api.a`).
 
 ## Example
 
-An example for driving the API in its current form is in the file [`call_bmc.cpp`](call_bmc.cpp),
+An example for driving the API in its current form is in the file [`call_bmc.cpp`](regression/call_bmc.cpp),
 which we are also using as a binary driver for testing the API.
