-==========
+# libscsicmd
 
 A library to create SCSI commands (CDBs) and parse the results, also for ATA commands and results.
 
 This library doesn't deal with actually submitting the CDBs or getting the results from the storage device, only with
 the commands themselves. The actual sending of the command is different between the different OSes and this library
 tries to be OS agnostic.
 
-Build
-=====
+## Build
 
 The build system is using cmake, you need to get it before you can build.
 
 To build, run:
-  cmake . && make
 
-Author
-======
+    cmake . && make
+
+For a developer debug build use:
+
+    cmake -DCMAKE_BUILD_TYPE=Debug .
+
+To build for American Fuzzy Lop instrumentation:
+
+    cmake -DCMAKE_BUILD_TYPE=Debug -DCMAKE_C_COMPILER=/usr/bin/afl-gcc -DCMAKE_C_FLAGS=-DAFL_HARDEN=1 .
+
+## Testing
+
+Testing is either done manually with some raw data collected from SCSI devices
+with test/collect\_raw\_data or with American Fuzzy Lop (AFL) for parsing
+problems.
+
+Using AFL:
+
+    afl-fuzz -t 200 -i afl/testcase -o afl/finding test/parse_scsi
