-Osmocom Iuh experimentation code
-(C) 2015 by Harald Welte <laforge@gnumonks.org>
-
-This code is a playground for implementing something along the lines of
-the an Iuh interface of a HNB-GW.  The intent is to later integrate this
-with OsmoNITB + OsmoSGSN, in order to have 3G capable 'network in the
-box'.
-
-h1. Building
-
-As external library dependencies, you will need
-* libosmocore from git://git.osmocom.org/libosmocore
-* libasn1c from git://git.osmocom.org/libasn1c
-* libsctp-dev (this is the package name in Debian)
-* libosmo-netif from git://git.osmocom.org/libosmo-netif (sysmocom/sctp branch)
-* libosmo-sccp from git://git.osmocom.org/libosmo-sccp (sysmocom/iu branch)
-
-To bootstrap the build, in the root directory, run:
-
-    autoreconf --install
-
-After that, run the usual
-
-    ./configure [options]
-    make
-    [sudo] make install
-
-h1. Using
-
-Note: osmo-iuh is in active development (December 2015, January 2016) so below
-statements may outdate rapidly.
-
-there's not much to use yet.  But if you run the 'hnbgw' executable,
-it will open a listening SCTP socket and wait for incoming Iuh
-connections.  It will accept any HNB-REGISTER-REQUEST, so the homeNodeB
-should start to establish RUA and RANAP (which we haven't implemented
-yet).
-
-h1. Regenerating C code from ASN.1 source
-
-In order to re-generate the C source code from the ASN.1 source,
-you will need a modified asn1c which has the following features:
-* APER support (the patch from Eurecom, or its forward-ported version
-  from the aper branch of git://git.osmocom.org/asn1c)
-* support for prefixing the generated types (aper-prefix branch of
-  git://git.osmocom.org/asn1c)

+osmo-iuh - Osmocom Iuh and HNB-GW implementation
+================================================
+
+This repository contains a C-language implementation of the 3GPP Iuh
+interface, together with a HNB-GW (Home NodeB Gateway).  You can use it
+to interface Iuh-speaking femtocells/small cells to Iu-speaking MSCs and
+SGSNs.
+
+It is part of the [Osmocom](https://osmocom.org/) Open Source Mobile
+Communications project.
+
+Homepage
+--------
+
+The official homepage of the project is
+https://osmocom.org/projects/osmohnbgw/wiki
+
+GIT Repository
+--------------
+
+You can clone from the official libosmocore.git repository using
+
+	git clone git://git.osmocom.org/osmo-iuh.git
+
+There is a cgit interface at http://git.osmocom.org/osmo-iuh/
+
+Documentation
+-------------
+
+There is currently no documentation beyond the wiki available on the
+homepage.  We would love to see somebody contributing a manual that can
+be part of the osmo-gsm-manuals suite.
+
+Mailing List
+------------
+
+Discussions related to osmo-iuh are happening on the
+openbsc@lists.osmocom.org mailing list, please see
+https://lists.osmocom.org/mailman/listinfo/openbsc for subscription
+options and the list archive.
+
+Please observe the [Osmocom Mailing List
+Rules](https://osmocom.org/projects/cellular-infrastructure/wiki/Mailing_List_Rules)
+when posting.
+
+Contributing
+------------
+
+Our coding standards are described at
+https://osmocom.org/projects/cellular-infrastructure/wiki/Coding_standards
+
+We us a gerrit based patch submission/review process for managing
+contributions.  Please see
+https://osmocom.org/projects/cellular-infrastructure/wiki/Gerrit for
+more details
+
+The current patch queue for osmo-iuh can be seen at

+
+
+Building
+--------
+
+It is generally best to check the wiki for the most up-to-date build
+instructions.
+
+As external library dependencies, you will need
+* libosmocore from git://git.osmocom.org/libosmocore
+* libasn1c from git://git.osmocom.org/libasn1c
+* libsctp-dev (this is the package name in Debian)
+* libosmo-netif from git://git.osmocom.org/libosmo-netif (sysmocom/sctp branch)
+* libosmo-sccp from git://git.osmocom.org/libosmo-sccp (sysmocom/iu branch)
+
+To bootstrap the build, in the root directory, run:
+
+    autoreconf --install
+
+After that, run the usual
+
+    ./configure [options]
+    make
+    [sudo] make install
+
+Using
+-----
+
+Note: osmo-iuh just left very active development (December 2015, January
+2016), so your mileage may vary.
+
+If you run the 'hnbgw' executable, it will open a listening SCTP socket
+and wait for incoming Iuh connections.  It will accept any
+HNB-REGISTER-REQUEST, and it will establish Iu (over SUA) connections
+towards the MSC and SGSN.
+
+Regenerating C code from ASN.1 source
+-------------------------------------
+
+In order to re-generate the C source code from the ASN.1 source,
+you will need a modified asn1c which has the following features:
+* APER support (the patch from Eurecom, or its forward-ported version
+  from the aper branch of git://git.osmocom.org/asn1c)
+* support for prefixing the generated types (aper-prefix branch of
