+### Introduction
 
 The Firmware Mod Kit allows for easy deconstruction and reconstruction of firmware images for various embedded devices. While it primarily targets Linux based routers, it should be compatible with most firmware that makes use of common firmware formats and file systems such as TRX/uImage and SquashFS/CramFS.

 In order to use the Firmware Mod Kit, you must have a subversion client, standard Linux development tools (gcc, make, etc), the python-magic module, and the zlib and lzma development packages. If you are running an linux distro that use apt-get, e.g. Ubuntu or Debian, use:

 For other distros, you should install the equivalent packages using your distro's package manager.
 
 The Firmware Mod Kit is only supported on the Linux platform. With a few small modifications, it should work on other POSIX platforms.

+#### Kit Executables
 
 The Firmware Mod Kit is a collection of utilities and shell scripts. The utilities can be used directly, or the shell scripts can be used to automate and combine common firmware operations (e.g. extract and rebuild). The core scripts to facilitate firmware operations are listed below.

-The Firmware Working Directory
+#### The Firmware Working Directory
 
 The Firmware Mod Kit uses a 'hard coded' working directory of 'fmk'. The extraction script extracts to this folder, and the rebuild script rebuilds from this folder. Allowance of alternate working directories is supported for some operations, but not all. We'll be expanding that in the future. For now, if you have multiple working directories, we suggest you rename the ones you're not currently operating on.
-Extracting Firmware
+
+#### Extracting Firmware
 
 Automated firmware extraction typically works with most firmware images that employ uImage/TRX firmware headers and use SquashFS or CramFS file systems. Currently, extract-firmware.sh is the preferred method of extraction as it supports more firmware types than the older old-extract.sh script. However, old-extract.sh is still included and works with many firmware formats.

 By default, output from extract-firmware.sh will be located in the 'fmk' directory, while old-extract.sh will place extracted data into the specified working directory.
-Re-Building Firmware

+#### Re-Building Firmware
 
 Which build script to use is dependant on which extraction script was used. If you extracted a firmware image with extract-firmware.sh, then you must use build-firmware.sh to re-build it. Likewise, if old-extract.sh was used, then old-build.sh must be invoked when re-building an image:

 The optional -nopad switch will instruct build-firmware.sh to NOT pad the firmware up to its original size.
 
 The optional -min switch will use the maximum squashfs block size of 1MB. This will decrease the firmware image size at the cost of additional CPU and RAM resources utilized on the target device. Do not use this switch unless you must. This is a very large block size for embedded systems. The original firmware squashfs block size is preserved on rebuild, and the original block size should be the one used unless you are sure you know what you're doing. Too large a block size may appear to work fine, but runtime performance of the firmware may suffer in all or some loads.

 Sometimes you'll enthusiastically flash a third-party firmware like Gargoyle or DD-WRT only to discover it lacks features you need, doesn't perform as well as the vendor firmware, or has functional problems. In this situation, you might find yourself wanting to go back to the vendor firmware, but have no way to do so!
