+## Summary
+
+<!--One paragraph explanation of the IPIP.-->
+This is the suggested template for new IPIPs.
+
+## Motivation
+
+AKA Problem Statement
+
+Clearly explain why the existing protocol specification is inadequate
+to address the problem that the IPIP solves.
+
+## Detailed design
+
+AKA Solution Proposal
+
+Describe the proposed solution and list all changes made to the specs repository.
+
+The resulting specification should be detailed enough to allow competing,
+interoperable implementations.
+
+When modifying an existing specification file, this section should provide a
+summary of changes. When adding new specification files, list all of them.
+
+## Design rationale
+
+The rationale fleshes out the specification by describing what motivated
+the design and why particular design decisions were made.
+
+Provide evidence of rough consensus and working code within the community,
+and discuss important objections or concerns raised during discussion.
+
+### User benefit
+
+How will end users benefit from this work?
+
+### Compatibility
+
+Explain the upgrade considerations for existing implementations.
+
+### Security
+
+Explain the security implications/considerations relevant to the proposed change.
+
+### Alternatives
+
+Describe alternate designs that were considered and related work.
+
+## Test fixtures
+
+List relevant CIDs. Describe how implementations can use them to determine
+specification compliance. This section can be skipped if IPIP does not deal
+with the way IPFS handles content-addressed data, or the modified specification
+file already includes this information.
