+We recommend that software projects receiving organizational support from SIPB and software developed for SIPB services be free software, with a public source code repository and a documented way of accepting contributions from the community.
+
+In particular, we recommend that the default license for source code and packaging for a SIPB project or service be either:
+
+1. the MIT license (also known as the "Expat" or "X11" license), or
+2. the GNU General Public License, permitting the use of version 2 or, at the licensee's option, any later version,
+
+unless there is a compelling reason to use another license.
+
+In addition, we recommend that projects have a publicly-readable source code repository, a public bug tracker, and directions on how to get involved with development linked from their home page, README, or
+equivalent starting point.
+
+Advice on how to license software packages and current best practices for collaboration with the community is available [[on a separate page|projects/collaboration]].
