+# Notes regarding Matrix, a decentralised conversation store
+
+As a lot of things require playing around with `/devtools` and raw state
+events, this is where I collect those and other things related to Matrix.
+
+Events are mostly named how they are used, but `retention` predates that so
+`m.room.retention` is a symlink to not break either links or muscle memory
+on terminal. `account-data` is an exception for appearing that way in `/devtools`
+(kind of) and clients (Element & FluffyChat) have their own directories.
+
+## Other notes not needing their own directories
+
+### Account migration
+
+* [EMS Matrix account migration tool](https://ems.element.io/tools/matrix-migration)
+  * Centralized, propietary, service, works less well since Synapse 1.11.0rc1
+    made PL50 requirement for inviting users to new rooms.
+* [Variate](https://github.com/ShadowJonathan/variate) is planning to be
+  a tool for *migrating between different Matrix server implementations*.
