+Flubber Config Build Progress
+-----------------------------
+
+You could check the last 10 lines in the build log for possible errors until build completion.
     $ tail -n 10 ./build_fpga_`# of cores`c/build.log
+Example: `tail -n 10 ./build_fpga_4c/build.log`
+
 Check if the build is still running by looking for quartus_sh, quartus_syn, or quartus_fit programs.
     $ ps -u `username`
+
 If the build fails and you need to restart it, clean up the build folder using the following command:
     $ make clean-fpga-`# of cores`c
-The following file should exist when the build is done:
+Example: `make clean-fpga-4c`
+
+The file `vortex_afu.gbs` should exist when the build is done:
     $ ls -lsa ./build_fpga_`# of cores`c/vortex_afu.gbs

+Signing the bitstream and Programming the FPGA
+----------------------------------------------

     $ cd ./build_fpga_`# of cores`c/
     $ PACSign PR -t UPDATE -H openssl_manager -i vortex_afu.gbs -o vortex_afu_unsigned_ssl.gbs

 FPGA sample test running OpenCL sgemm kernel
 --------------------------------------------
+
 Run the following from the Vortex root directory
-    $ ./ci/blackbox.sh --driver=fpga --app=sgemm --args="-n64"
+    $ ./ci/blackbox.sh --driver=fpga --app=sgemm --args="-n64"
+
+Build Script Configuration
+--------------------------
+
+Inside the ci folder there is a script called `blackbox.sh` which runs different tests on the Vortex processor with different configurations. Run:
+    $ ./ci/blackbox.sh --help
+To see the different configuration options available.
+The most important ones are `--driver`, which runs the Vortex test on either the fpga, rtlsim, vlsim, or simx simulators, and `--perf`, which enables the profiling counters for each core.
