- come straight to point: how to clone (don't talk about git config)
- refer to contributing documentation where necessary instead of
  repeating information

- CellGroupConfig is handled through DU (hence MAC)
- mention number of DUs/CU-UPs handled per CU-CP
- mention number of UEs handled
- take out BWPs, as we don't support it properly
- typos

* !2795 NR UE NL assertion
* !2802 Fix regression in ue-scan-carrier option
* !2806 Minor fixes to wireshark documentation
* !2807 Add assertion for known segfault during teardown of gNB
* !2809 Inversion in flags name
* !2697 SIDELINK PSBCH: MAC->PHY cfg, Scheduler + supporting functions, enable system testing & scope
* !2808 NR UE DLSCH MCS table selection improvements

	- Phy config update and Sidelink frame parameters initialisation
	- PSBCH scheduler to trigger TX PSBCH/RX PSBCH actions
	- Sidelink indication with rx ind to trigger send SL-MIB to MAC
	- Enable Scope for PSBCH use -d or --dqt
	- Enable system testing of PSBCH for example using RFSIMULATOR:

		- UE1 is a SYNCRONISATION SOURCE UE which transmits PSBCH

		  started using command -
		  sudo ./nr-uesoftmodem --sl-mode 2 --sync-ref 4 --rfsim --rfsimulator.serveraddr server

		- UE2 syncs onto UE1 during sidelink search, gets the timing and continues to receive PSBCH

		  started using command -
		  sudo ./nr-uesoftmodem --sl-mode 2 --rfsim --rfsimulator.serveraddr 127.0.0.1

		- In the default use case 2 Sidelink SSBs sent over 16 frames.

		- In case SL-SSB configuration needs to be changed use -O option in the above command like

		-O ../../../targets/PROJECTS/NR-SIDELINK/CONF/sidelink_preconfig_1txpool.conf
