-This tutorial contains instructions for running srsLTE eNB and UE on COSMOS.
-A more detailed tutorial can be found in [https://github.com/srsLTE/srsLTE srsRAN git README] as well as in the [https://docs.srsran.com/en/latest/ srsRAN documentation pages].
-
-== Prerequisites ==
-1. Two nodes, with appropriate hardware, within RF range
-1. Currently supported: USRP X310, USRP B210
-1. Load the image {{{tutorial-srslte.ndz}}} onto both nodes
-1. Turn the nodes on
-1. ssh to the nodes
-
-== On node 1 ==
-1. run srsepc
-1. run srsenb
-
-
-For further configuration details, please consult the official srsLTE webpage and documentation.
-
-== On node 2 ==
-1. run srsue
-
-
-== Once Both nodes are running ==
-* if all is successful, you should see new interfaces on the two nodes, with addresses:
-  * 172.16.0.1
-  * 172.16.0.2
-* you should be able to run ping, iperf, and so on
-
-
-== Specifics per domain ==
-
-=== sb1.cosmos-lab.org and sb2.cosmos-lab.org ===
-1. Use 2974
-1. set usrp address to "type=x3xx,resource=rio0"
-1. use RFSWITCH service to set all switches to port 1 for antenna
- port 1 for antenna
-
-=== sb2.orbit-lab.org ===
-1. set usrp address to "type=x3xx,addr=192.168.40.2"
-1. bring up usrp ethernet interface, set ip to 192.168.40.1/16
-
-=== sb1.orbit-lab.org ===
-1. set usrp address to "type=b210"
-
-=== sb4.orbit-lab.org ===
-1. set usrp address to "type=b210"
-1. configure RF matrix for 60db of attenuation between eNB and UE node chosen
+== srsRAN 5G network in COSMOS SB1 ==
+srsRAN is an open-source  software radio suite for 4G/5G provided by SRS(Software Radio Systems).
+The srsRAN suite includes:
+srsUE - a full-stack SDR 4G/5G UE application
+srsENB - a full-stack SDR 4G/5G e(g)NodeB application
+srsEPC - a light-weight 4G core network implementation with MME, HSS and S/P-GW
+Source code for srsRAN can be found [https://github.com/srsran/srsRAN here] and documentation can be found [https://docs.srsran.com/en/latest/ here]
+
+
+
+=== Description ===
+This tutorial contains instructions for setting up a 4G/5G network in COSMOS SB1. 
+
+=== Prerequisites ===
+In order to access the test bed, create a reservation and have it approved by the reservation service. Access to the resources is granted after the reservation is confirmed. Please follow the process shown on the COSMOS [wiki:GettingStarted getting started] page to get started. 
+
+=== Resources required ===
+1 USRP-2974, 1 COSMOS node with SIM8200 modem.
+in [https://wiki.cosmos-lab.org/wiki/Architecture/Domains/cosmos_weekshall COSMOS Weeks hall] domain
+
+=== Tutorial Setup ===
+
+Follow the steps below to gain access to the [wiki:/Architecture/Domains/cosmos_sb1 Weeks hall console] and set up nodes with appropriate images. 
+ 1. If you don't have one already, sign up for a [https://www.cosmos-lab.org/portal-2/ COSMOS account]
+ 1. [wiki:/GettingStarted#MakeaReservation Create a resource reservation] on sandbox 1
+ 1. [wiki:/GettingStarted#LogintoyourReservation Login] into sandbox 1 console (console.sb1.cosmos-lab.org) with two SSH sessions. 
+ 1. Make sure all the resources in the domain are turned off:
+{{{#!shell
+omf tell -a offh -t system:topo:allres  
+}}}
+ For this tutorial we will be using a USRP-2974 sdr2-s1-lg1 and a COSMOS node srv1-in1. srv1-in1 has a [https://www.waveshare.com/sim8200-m2.htm Waveshare SIM8200 modem] attached over USB.
+ 1. Load amarisoft-2974.ndz on sdr2-s1-lg1
+{{{#!shell
+omf load -i amarisoft-2974.ndz -t sdr2-s1-lg1
+}}}
+{{{#!shell
+omf load -i waveshare-sim8200.ndz -t srv1-in1
+}}}
+ 1. Turn all the required resources on and check the status
+{{{#!shell
+omf tell -a on -t srv1-in1,sdr2-s1-lg1
+}}}
+{{{#!shell
+omf stat -t system:topo:allres
+}}}
+ 1. ssh to the nodes, use option -Y for using GUI.
+
+=== Tutorial Execution ===
+==== Run the Amarisoft MME ====
+* Upon logging into sdr2-s1-lg1, run uhd_find_devices to check the USRP.
