Welcome to the GovHack toolkit. This page provides all the information you need to prepare hackfest entries. Welcome to the GovHack toolkit. This page provides all the information you need to prepare hackfest entries.
These tools can be used to make entries like: mobile apps, web apps, data visualisations/infographics These tools can be used to make entries like: mobile apps, web apps, data visualisations/infographics
   
  # How to register and submit your entry
- govhack toolkit!!!! ## registering your team
- key datasets, directory.gov.au gazetter/AEC electorates/suburbs/postcodes/LGAs TODO how to use website "Hacker Space" to register and find teams etc.
   
- definitions, open licence reuse permissive hacker hack data journalism data bis UCX etc. ## preparing your submission
- what do govhack entries look like?  
  You should record a 3 minute speech and mix images/text to accompany.
  http://www.screenr.com/ and other screencasting tools allow you to demo apps.
  To mix together clips, you can use youtube video editor http://www.youtube.com/editor or local software like http://www.videolan.org/vlmc/ or http://www.lwks.com/
   
  You also need to submit your "source material". For an application this may be source code, for another work it might be your notes or prototypes.
  The key thing here is that your source material demonstrates to the judges that some of the end result was your own work and that it is possible for another person to replicate that work.
