+## 🐞 Bug Report
+
+A clear and concise description of what the bug is.
+
+## What is the severity of this bug?
+
+**Critical - Urgent:** We can't do anything if this isn't actioned immediately (product doesn't function without this, it's blocking us or users, or it resolves a high severity security issue). Whole team should drop what they're doing and work on this. 
+
+**Critical:** We can't do anything if this isn't actioned immediately (product doesn't function without this, it's blocking us or users, or it resolves a high severity security issue). One person should look at this right now. 
+
+**Important:** * We have to do this before we ship, but it can wait until the next sprint (product or feature won't function without it, but it's not blocking us or users right now). Team should do this in the next sprint.
+
+**Should have:** * It would be better if we do this before we ship, but it's OK if we don't (product functions without this, but it's a better user experience). Consider adding to a future sprint.
+
+**Could have:** It really doesn't matter if we do this (product functions without this, impact to user is minimal).

+## Context
+
+Why are we doing this work? How does it interact with other work being done? For example:
+
+Access nodes need to receive transactions in order to store them, so we need a communication solution for relaying transactions between access nodes.
+
+## Definition of Done
+
+What do we need to achieve to consider this issue resolved? For example:
+
+* Access nodes must send transactions to at least some of their peers
+* Processing hooks are in place for received transactions, to be implemented in a later issue
+* Transactions must be received by the entire network, although this doesn't have to be immediate (i.e. transactions could be gossiped)
+
+## Further reading:

+Any additional materials that provide context and background, beyond the typical scope for an issue. For example this might be links to the Bamboo technical primer.
