 What you need for the workshop (quick overview):
 
-- [Julia 1.8](https://julialang.org/downloads/)
+- [Julia 1.9](https://julialang.org/downloads/)
 - [Jupyter](https://jupyter.org/) and [IJulia.jl](https://github.com/JuliaLang/IJulia.jl)
 - This repository of workshop materials
 - All required dependencies (Julia packages) for the workshop
 
 ### Getting Julia
-For following the course you will need at least **Julia 1.8**.
+For following the course you will need **Julia 1.9**.
 Julia can be easily obtained in binary form from [Julia downloads](https://julialang.org/downloads/).
 
 ### Getting all the rest
-To get the remaining files and dependencies
-start up `julia` and in the resulting REPL shell,
-copy and paste the following:
-
-```julia
-import Downloads
-script = Downloads.download("https://gitlab.mathematik.uni-stuttgart.de/stammbn/julia-seminar/-/raw/main/install.jl?ref_type=heads")
-include(script)

+### Starting the notebook
+To start the notebook make sure to be in the folder `Julia-seminar` and then run `julia`: an interactive Julia command line will open. In there run this command

+```
+using IJulia; notebook(dir=pwd())
+```
