for JIRA

Documents add-on lets you manage and store files in JIRA on a project level.
It adds an additional tab named "Documents" to the project dashboard where you can post documents related to that project, making them available to other project members.
The files that you attach are stored in JIRA, more exactly in a sub-folder of the JIRA attachments folder, thus simplifying your administrative and backup procedures.
The access to the Documents tab and different operations on the posted documents are configurable via permissions settings.
