 # cpp-client
 C++ OpenTracing binding for Jaeger
 
+## Generated files
+
+This project uses Apache Thrift for wire-format protocol support code
+generation. It currently requires exactly Thrift 0.9.2 or 0.9.3. Patches have
+been applied to the generated code so it cannot be directly re-generated from
+the IDL in the `idl` submodule
+
+(see https://github.com/jaegertracing/cpp-client/issues/45)
+
+The code can be re-generated with
+
+    git submodule init
+    git submodule update
+    find idl/thrift/ -type f -name \*.thrift -exec thrift -gen cpp -out src/jaegertracing/thrift-gen {} \;
+
+but at time of writing (Thrift 0.11.0) the resulting code is invalid due to
+https://issues.apache.org/jira/browse/THRIFT-4484
