 ## Quick start
 
-Running analysis script can be done using `fccanalysis` command which is shipped in Key4hep stack:
-
-```shell
-source /cvmfs/sw.hsf.org/key4hep/setup.sh
-fccanalysis run analysis_script.py
+In order to run over pre-generated samples from `winter2023` or `spring2021`
+campaigns one needs to compile `pre-edm4hep1` branch of the FCCAnalyses in the
+`2024-03-10` release (hard coded into the `setup.sh` script)
+
+```sh
+git clone --branch pre-edm4hep1 git@github.com:HEP-FCC/FCCAnalyses.git
+cd FCCAnalyses
+source ./setup.sh
+fccanalysis build -j 8
 ```
 
-To have access to the FCC pre-generated samples, one needs to be subscribed to one of the following e-groups (with owner approval)
-`fcc-eos-read-xx` with `xx = ee,hh,eh`.
