-$ brew install ctags
-$ easy_install python-ctags simplejson
-$ tar -zxvf linux-2.6.35.4.tar.gz
-$ cd linux-2.6.35.4

+* Install ctags (http://ctags.sourceforge.net)
+* `easy_install python-ctags simplejson`
+* Download and extract the Linux kernel sources (https://www.kernel.org)
+* Move the extraced folder to `/usr/src/linux-$VERSION`
+* `chmod +x prepare-files.sh && ./prepare-files.sh`
+* :coffee: or :beer:
 
 ## Web
 * uses [jQuery DataTables](http://datatables.net/) to pull JSON file and format table
 * links to http://lxr.free-electrons.com for source cross-reference and http://www.kernel.org for manpages
 * `www` dir checked into gh-pages branch w/ JSON file using `deploy.sh`
 
-## Other
-* only tested on 2.6 kernel versions, needs to be updated
-* largely unmaintained, feel free to open a PR and help out!
