To contribute to ThinkUp, you will want to manually install the files direct from the source repository.

Here are installation guides by operating system.

• Installation: Dreamhost - How to install ThinkUp on Dreamhost. This applies to many common web hosting setups, even if you're not specifically on Dreamhost.
• Installation: Windows - Notes on installing ThinkUp on Windows.

ThinkUp is under rapid development right now, so files change fast. If you used git clone git://github.com/ginatrapani/ThinkUp.git to get ThinkUp files initially, use git pull origin master to get updates.

If there's been a database migration since the last time you built your database (check the db_migrations folder), run the SQL script against your database to update it.
