     1== Basic usage ==
     2
     3=== Desciption ===
     4In this tutorial we'll demonstrate how to navigate from the COSMOS sandbox to a single SDR on a node and run an application to read samples from the SDR.
     5
     6=== Prerequisites ===
     7Before getting started you'll need the following:
     8 1. sign up for a [https://cosmos-lab.org/portal-2/ COSMOS account]
     9 2. create a reservation for sandbox 1 using the [https://wiki.cosmos-lab.org/cPanel/controlPanel/start scheduler].
     10 3. some minimal knowledge or interest of Linux
     11
     12=== Set up ===
     13 * After your reservation request has been approved, you'll receive access to the sandbox1 console.
     14Open a terminal into console.sb1.cosmos-lab.org with a tunnel set up from localhost:5000 to srv1-lg1.sb1.cosmos-lab.org:9002

     35 * We can see the available nodes under this sandbox using the ''omf stat -t all'' command. The nodes list below should coinside with the [https://wiki.cosmos-lab.org/cPanel/controlPanel/start Inventory/Status page].

     45 * For this example we'll use the node ''srv1-lg1.sb1.cosmos-lab.org'' and load the ''baseline-sdr.ndz'' image onto it. This image already has the applications pre-compiled and drivers installed.
     46{{{
     47console:~$ omf load -i baseline-sdr.ndz  -t srv1-lg1.sb1.cosmos-lab.org

     49 After the image is successfully loaded turn on the node, give it some time to boot and then ssh into it.
