+Usage
+-----
+
+In order to use isafw during the image build, drop the isafw.bbclass
+to your target layer class folder, as well as other bb recipes to 
+the corresponding recipe folder (recipes-devtools is a good default
+location). Then add the following line to your build/conf/local.conf
+file:
+
+INHERIT += "isafw"
+ 
+Also, some isafw plugins require network connection, so in case of a
+proxy setup please make sure to export http_proxy variable into your 
+environment.
+
+In order to produce image reports, you can execute image build 
+normally. For example:
+
+bitbake target-image
+
+If you are only interested to produce a report based on packages 
+and without building an image, please use:
+
+bitbake -c analyse_sources_all target-image
+
+
+Logs
+----
+
+All isafw plugins by default create their logs under the 
+${LOG_DIR}/isafw-report/ directory, where ${LOG_DIR} is a bitbake 
+default location for log files. If you wish to change this location, 
+please define ISAFW_REPORTDIR variable in your local.conf file.
