@@ -3,5 +3,20 @@ gcc for Unikraft
 
 This is the port of gcc for Unikraft as external library.
 
+For the time being only libbacktrace and libffi libraries are ported because 
they are 
+needed for the libgo port. You will need newlib for both libraries. 
+
+For libffi you will need pthread\_embedded external library too.
+
+Also for libbacktrace you will need the below external libraries:
++ compiler-rt 
++ libunwind
++ libcxx
++ libcxxabi
+
+Moreover because of a bug in libunwind: `unw_getcontext` leads to page fault, 
+`backtrace_full` function will also lead to page fault, as it uses 
`_Unwind_Backtrace`
+which calls `unw_getcontext`.
+
 Please refer to the `README.md` as well as the documentation in the `doc/`
 subdirectory of the main unikraft repository.
