Installation techniques

Difference between Install and Upgrade
If you have installed erp5_forge business template, and are a bleeding-edge type, you can from time to time update your system to the latest svn revision - see http://wiki.erp5.org/HowToUseERP5Subversion#update_from_svn.

Usually, the recommended way would be to first update the source code (by running svn_update.sh script), then update all bt5 starting from the more basic ones and on to the application-level, so it'd go more or less like:
 * erp5_core
 * erp5_xhtml_style
 * erp5_mysql_innodb_catalog
 * erp5_pdm
 * erp5_trade

Creation
See http://wiki.erp5.org/HowToCreateBusinessTemplates
