 performing the following steps:
 
   1. Clone the repository:
-     ```
+     ```bash
      git clone [email protected]:trixi-framework/Trixi.jl.git
      ```
   2. Enter the cloned directory and run the following command to install all

-     ```
+     ```bash
      julia utils/install.jl
      ```
 
+Trixi is also a registered Julia package. Hence, you can also install Trixi via
+```julia
+julia> import Pkg
+
+julia> Pkg.add("Trixi")
+```
+If you do this and want to modify Trixi, you can run
+```julia
+julia> Pkg.dev("Trixi") # get a clone of the git repository, usually in ~/.julia/dev/Trixi
