-## 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.
