+## Version
+
+This document describes component versions:
+
+* `urdt-ussd` `v0.5.0-beta`
+* `go-vise` `v0.2.2`
+
+
+## User profile data
+
+All user profile items are stored under keys matching the user's session id, prefixed with the 8-bit value `git.defalsify.org/vise.git/db.DATATYPE_USERDATA` (32), and followed with a 16-big big-endian value subprefix.
+
+For example, given the sessionId `+254123` and the key `git.grassecon.net/urdt-ussd/common.DATA_PUBLIC_KEY` (2) will be stored under the key:
+
+```
+0x322b3235343132330002
+
+prefix   sessionid       subprefix
+32       2b323534313233  0002
+```
+
+### Sub-prefixes
+
+All sub-prefixes are defined as constants in the `git.grassecon.net/urdt-ussd/common` package. The constant names have the prefix `DATA_`
+
+Please refer to inline godoc documentation for the `git.grassecon.net/urdt-ussd/common` package for details on each data item.
