Unzip the latest release of the payments module plugin to your ArchivesSpace plugins directory:
$ cd /path/to/archivesspace/plugins
$ unzip payments_module.zip -d payments_module
Enable the plugin by editing your ArchivesSpace configuration file
(config/config.rb):
AppConfig[:plugins] = ['other_plugin', 'payments_module']
(Make sure you uncomment this line (i.e., remove the leading '#' if present))

You will need to shut down ArchivesSpace and migrate the database:
$ cd /path/to/archivesspace
$ scripts/setup-database.sh
This will create the tables required by the payments module, and will optionally pre-populate the system from a file of fund codes. To do this, you will need to provide a TSV (tab-delimited) file of the form:
fund_code_1 [tab] description_of_fund_code_1
fund_code_2 [tab] description_of_fund_code_2
fund_code_3 [tab] description_of_fund_code_3
The setup-database script will prompt you to enter the full path to
this file.
