Step 1: Downloading
First you want to download the most recent version of the file. To do this please visit the files section.
Step 2: Extraction
Once you have obtained the most recent version of the file you will want to extract the file to your plugins folder. Before doing this ensure have you the most recent version of the plugin; as well as the most recent version of Bukkit.
Step 3: Starting 'er up!
Once the files are in place start your server and the configuration files should be created. You should see the following files in your plugins/BOSEconomy folder. Ensure all of these files have the default information in them.
NOTE: If you have no other brackets defined but default and you do not change the "exclude" value to false, /top5 will not work because it will exclude everybody who is in the default bracket. For simple systems turn this setting to false.
If the plugin ran correctly and everything was installed as it should be you should see the following files in your plugins/BOSEconomy dir.
