-  - clone the git repository for the main software application (Ph2_ACF), and check out the latest stable release (`IT-v3.9`, at the time of writing): +=== Configuration of FC7 ===
-    ``` +
-    git clone https://gitlab.cern.ch/cmsinnertracker/Ph2_ACF.git -o cmsinnertracker +
-    cd Ph2_ACF +
-    git checkout -b b_IT_v3p9 IT-v3.9 +
-    ```+
  
 +General information and instructions on the FC7 setup and the related software can be found in the material of the [[https://indico.cern.ch/event/842824|2019 Phase-2 Tracker DAQ Workshop]]. The instructions listed below are a selected summary of the instructions given in the latter workshop (and references therein).
  
 +  * Follow the instructions in https://indico.cern.ch/event/842824/attachments/1920624/3177632/PreparingFC7.pdf \\ \\

 +#!/bin/bash
 +
 +sudo wget http://download-ib01.fedoraproject.org/pub/epel/6/x86_64/Packages/r/rarpd-ss981107-42.el6.x86_64.rpm

 +</code>
 +      - clone the git repository for the main software application (''Ph2_ACF''), and check out the latest stable release \\ (the name of the latest stable release should be in the ''README'' file of the repository; at the time of writing, it is ''IT-v3.9.4''): \\ \\ <code bash>
 +git clone https://gitlab.cern.ch/cmsinnertracker/Ph2_ACF.git -o cmsinnertracker
 +cd Ph2_ACF
 +git checkout -b b_IT_v3p9p4 IT-v3.9.4
 +</code>
 +      - Follow the instructions in ''Ph2_ACF/README.md'' and install all the necessary dependencies; as of Aug-2020, this corresponds to the following commands (double-check the instructions in the official documentation, before executing these): \\ \\ <code bash>
 +sudo yum -y install epel-release
 +sudo yum -y install pugixml-devel
 +sudo yum -y install boost-devel
 +sudo yum -y install root
 +sudo curl http://ipbus.web.cern.ch/ipbus/doc/user/html/_downloads/ipbus-sw.centos7.x86_64.repo -o /etc/yum.repos.d/ipbus-sw.repo
 +sudo yum clean all
 +sudo yum -y groupinstall uhal
 +sudo yum -y install cmake
 +</code> **Note**: these steps are expected to work out-of-the-box on a recent version of ''CentOS7-x86_64''; they may not work on other types of OSs, e.g. ''CentOS7-i386'' (32-bit); in the latter case, some of the relevant dependencies (e.g. ''pugixml'', ''root'', ''uhal'') must be installed from source, following the instructions in the documentation of each package. The installation of ''Ph2_ACF'' and its dependencies on ''CentOS7-i386'' (32bit) was performed successfully (so it is possible), but it is not fully documented here; it did require the manual installation of ''pugixml'', ''root'', and ''uhal''.
 +
 +=== Testing with Ph2_ACF ===
 +
 +This section is work-in-progress. For the moment, the reader is referred to the documentation in the ''Ph2_ACF'' repository, and the material of the [[https://indico.cern.ch/event/842824|2019 Phase-2 Tracker DAQ Workshop]].
