 Binwalk relies on multiple external utilties in order to automatically extract/decompress files and data:
 
 ```bash
-$ sudo apt-get install mtd-utils zlib1g-dev liblzma-dev ncompress gzip bzip2 tar arj lhasa p7zip p7zip-full cabextract openjdk-6-jdk cramfsprogs cramfsswap

+About
+-----
+
+The libraries in this directory have been patched, extended, or otherwise modified from their original versions for use with binwalk.
+Some may include third-party modifications not available in the standard library release.
+
+Package mantainers should consult their particular distribution's rules regarding bundled libraries.
+
+Installation
+------------
+
+These libraries will be built and installed by default, unless the `--disable-clibs` option is provided to the configure script.
+
+The libraries will be installed to the `lib` sub-directory of the binwalk Python module so as to not conflict with existing libraries on the system.

+The libraries contained in this directory are provided for convenience of installation, and have not been modified.
+
+Package maintainers can generally replace these libraries with standard libraries from their particular distribution's package repository, however, the root `INSTALL.md` file should be consulted first.
