-Generating the android_filesystem_config.h:
+The fs_config_generator.py tool uses the platform android_filesystem_config.h and the
+TARGET_FS_CONFIG_GEN files to generate the fs_config_dirs and fs_config_files files for each
+partition, as well as passwd and group files, and the generated_oem_aid.h header.
 
-To generate the android_filesystem_config.h file, one can set
-TARGET_FS_CONFIG_GEN, which can be a list of intermediate fs configuration
-files.
+The fs_config_dirs and fs_config_files binary files are interpreted by the libcutils fs_config()
+function, along with the built-in defaults, to serve as overrides to complete the results. The
+Target files are used by filesystem and adb tools to ensure that the file and directory properties
+are preserved during runtime operations. The host files in the ${OUT} directory are used in the
+final stages when building the filesystem images to set the file and directory properties.
 
-The parsing of the config file follows the Python ConfigParser specification,
-with the sections and fields as defined below. There are two types of sections,
-both sections require all options to be specified. The first section type is
-the "caps" section.
+See ./fs_config_generator.py fsconfig --help for how these files are generated.
+
+The passwd and group files are formatted as documented in man pages passwd(5) and group(5) and used
+by bionic for implementing getpwnam() and related functions.
+
+See ./fs_config_generator.py passwd --help and ./fs_config_generator.py group --help for how these
+files are generated.
+
+The generated_oem_aid.h creates identifiers for non-platform AIDs for developers wishing to use them
+in their native code.  To do so, include the oemaids_headers header library in the corresponding
+makefile and #include "generated_oem_aid.h" in the code wishing to use these identifiers.

-For systems with separate partition images, such as vendor or oem,
-fs_config_generate can be instructed to filter the specific file references

-  This makes sure the results only contain content associated with the
