 # EDM4hep in Julia
 Prototype of the [EDM4hep](https://github.com/key4hep/EDM4hep) (generic Event Data Model for HEP experiments part of Key4hep) for Julia with the goal to have very simple structures (isbits) with the purpose to evaluate its ergonomic design and implementation performance.

+## Installation
+The package has been registered in the General Julia registry therefore its installation is simply using the `Pkg` packager manager.
+```
+julia -e ‘import Pkg; Pkg.add(“EDM4hep”)’
+```
+
+## Getting Started
+```julia
+julia> using EDM4hep
+julia> using EDM4hep.RootIO
+julia> file = "root://eospublic.cern.ch//eos/experiment/fcc/ee/generation/DelphesEvents/winter2023/IDEA/p8_ee_ZZ_ecm240/events_000189367.root"
+julia> reader = RootIO.Reader(file)
