 ### Getting Started
 
 After exporting a `BundledProgram`, runtime profiling and debug data can be collected in an ``ETDump``. An ``ETDump`` is a buffer containing data generated by hooks within the ExecuTorch runtime.
-We offer an example runner that accepts a `BundledProgram` (`.bp`) and runs a single iteration over the first method defined.
+We offer an example runner that accepts a `BundledProgram` (`.bpte`) and runs a single iteration over the first method defined.
 
 Running the program will generate an `ETDump` file (`.etdp`) at the location specified by `--etdump_path`. Make sure to build the program as specified below to enable the event tracer.
