Thanks to our hard working community members William Parker and Noah Dietrich, the installation guides for Snort 2.9.8.0 have been posted on Snort.org!
We love it when our community pitches in and sends us documentation, FAQ updates, startup scripts, hints and tricks (which belong in the FAQ!)
If you'd like to contribute to the documentation repository, just email us at sfcommunity@cisco.com, and we can highlight your work, or, if you'd like to help out with the FAQ, we host it on Github, and allow anyone to submit a pull request against the docs. Please considering helping out!
