What you’ll need to have already set up:
MySQL Server
A Working Chivalry Server
Step 1: Install the latest b3 from their website http://files.cucurb.net/b3/daily/.
Use the ones ending with win32.zip
Step 2: Extract the files to a folder.
Step 3: Make your configuration file http://config.bigbrotherbot.net/form.php?parser=chiv.
Enter your Database Configuration (Username, Password, IP, and DB Name)
Server Query Port is the QueryPort you set under PCServer-UDKEngine

Rcon Port is the Port you set under PCServer-UDKGame (You might have to add this to the file)

Rcon Password is the adminpassword you set in PCServer-UDKGame

Make sure the Update Settings are set to Dev
Enable any plugins you want.
Step 4: Upload the SQL file from B3 to initialize the database
The file is in C:%B3_Installation_dir%\sql\b3.sql.
You can use PHPMyAdmin or MySQL Workbench to do this.
When you are done you should see all of the tables.
Step 5: Start B3
Run b3_run.exe in your B3 installation directory.
Should look like this if it started correctly:
