+FMN replacement research
+========================
+
+`FMN <https://apps.fedoraproject.org/notifications/>`_ is application where users with fedora account
+setup notifications to be sent on fedora-messaging messages that match a specific filter.
+
+Our current deployment running on https://apps.fedoraproject.org/notifications/.
+
+It uses https://github.com/fedora-infra/fmn
+
+The software is currently under our fedora-infra organization.
+
+Abstract take-away
+------------------
+
+FMN is a project that allows people in our community to get notified when messages that interest them
+fire on the message-bus, making the message-bus more useful to people that are not
+directly developing or troubleshooting applications running in our infra.
+
+This means we really don't want to drop it's support.
+
+A two person team with skill in python development, with access to current FMN infrastructure,
+and ability to run deployment playbooks should be able to finish
+the work started in Pierre's POC and end up with up-to-date and more maintainable project.
+
+Solutions to be explored
+------------------------
+
+We have three options:
+
+- Upgrade FMN to supported version of Python and invest in the maintenance
+- Create a new bespoke application and invest in the maintenanece
+- Find off-the shelf application that would fill the role without us needing to maintain it
+
+Currently we are proposing primarily the first option.
+
+Preliminary notes on maintianing current FMN
+--------------------------------
+
+Based on Pierre's POC, FMN is upgrade-able to recent versions 
+of python and its libraries.
+
+This suggests it is prudent to invest in it further
+
+- FMN is key piece to fullfil the promise of having a message-bus useful to our community
+- green-field development is more costly and harder to ramp up
+
+Outstanding issues to be tackled by the initiative:
+
+- verify the upgrades actually work by thorough testing
+- migrate FMN to the fedora-messaging message-bus, as it still relies on  fedmsg
+- improve it's development state, by improving the test coverage, adding more static-checks e.t.c.
+
+
+Preliminary notes on using other off-the-shelf applications
+-------------------------------------
+
+As we want people to be able to get notified on messages on the bus,
+we'd need to integrate with our fedora-messaging infrastructure and our
+account system. We didn't find application that could be deployed and
+fullfil all of the needs FMN currently serves
+
+
+Create a new bespoke application that better suits our needs
+----------------------------------------------------
+
+This is an option we'd take if and only if the path of maintaining the original application
+was not feasible, or there was some way to greatly simplify the new implementation.
+
+With FMN neither is the case.
