+For the Bronze Release only a SW FEC is available so this step is not needed, for later releases the required information will be added to the document.

+Customize a setup environment shell script
+------------------------------------------
+Using as an example the provided in the folder phy\\setupenv.sh as the starting point
+customize this script to provide the paths to the tools and libraries that
+are used building and running the code.
+You can add for example the following entries based on your particular installation and the
+following illustration is just an example::
+
+- export DIR_ROOT=/home/
+- #set the L1 binary root DIR
+- export DIR_ROOT_L1_BIN=$DIR_ROOT/FlexRAN
+- #set the phy root DIR
+- export DIR_ROOT_PHY=$DIR_ROOT/phy
+- #set the DPDK root DIR
+- #export DIR_ROOT_DPDK=/home/dpdk-19.11
+- #set the GTEST root DIR
+- #export DIR_ROOT_GTEST=/home/gtest/gtest-1.7.0
+- export DIR_WIRELESS_TEST_5G=$DIR_ROOT_L1_BIN/testcase
+- export DIR_WIRELESS_SDK=$DIR_ROOT_L1_BIN/sdk/build-avx512-icc
+- export DIR_WIRELESS_TABLE_5G=$DIR_ROOT_L1_BIN/l1/bin/nr5g/gnb/l1/table
+- #source /opt/intel/system_studio_2019/bin/iccvars.sh intel64 -platform linux
+- export XRAN_DIR=$DIR_ROOT_PHY/fhi_lib
+- export XRAN_LIB_SO=true
+- export RTE_TARGET=x86_64-native-linuxapp-icc
+- #export RTE_SDK=$DIR_ROOT_DPDK
+- #export DESTDIR=""
+- #export GTEST_ROOT=$DIR_ROOT_GTEST
+- export ORAN_5G_FAPI=true
+- export DIR_WIRELESS_WLS=$DIR_ROOT_PHY/wls_lib
+- export DEBUG_MODE=true
+- export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$DIR_WIRELESS_WLS:$XRAN_DIR/lib/build
+- export DIR_WIRELESS=$DIR_ROOT_L1_BIN/l1
+- export DIR_WIRELESS_ORAN_5G_FAPI=$DIR_ROOT_PHY/fapi_5g
+- export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$DIR_ROOT_L1_BIN/libs/cpa/bin
+
+Then issue::
+
+- source ./setupenv.sh
+
+This sets up the correct environment to build the code
+
+Then build the wls_lib, FHI_Lib, 5G FAPI TM prior to running the code with the steps described in the Run L1 section
