 ### Usage - command line
 
+#### Option 1: Install as Julia Pkg App (Recommended for Julia 1.9+)
+
+```bash
+julia -e 'using Pkg; Pkg.add("ROMEO", app=true)'
+```
+
+After installation, you can run ROMEO directly from the command line (make sure `~/.julia/bin` is in your PATH):
+
+```bash
+$ romeo phase.nii -m mag.nii -t [2.1,4.2,6.3] -o results
+```
+
+See [App Installation Guide](docs/app_installation.md) for more details.
+
+#### Option 2: Using romeo.jl Script
+
 Install Julia 1.9 or newer (https://julialang.org)  
 Copy the file [romeo.jl](https://github.com/korbinian90/ROMEO.jl/blob/master/romeo.jl) from this repository to a convenient location. An alias for `romeo` as `julia <path-to-file>/romeo.jl` might be useful.
 
 ```bash
-    $ julia <path-to-file>/romeo.jl phase.nii -m mag.nii -t [2.1,4.2,6.3] -o results
+$ julia <path-to-file>/romeo.jl phase.nii -m mag.nii -t [2.1,4.2,6.3] -o results
 ```
 
 On the first run, the dependencies will be installed automatically.

+# Installing ROMEO as a Julia App
+
+ROMEO can be installed as a Julia Pkg app, which provides convenient command-line access to the `unwrapping_main` function.
+
+## Installation
+
+### Using Julia 1.9 or later:
+
+```julia
+using Pkg
+Pkg.add("ROMEO", app=true)
+```
+
+Or from the Pkg REPL (press `]` in Julia):
+
+```
+pkg> app add ROMEO
+```
+
+This will install the `romeo` command-line tool to `~/.julia/bin/romeo`. Make sure `~/.julia/bin` is in your system PATH for easy access.
+
+## Usage
+
+After installation, you can run ROMEO from the command line:
+
+```bash
+romeo --help
+romeo --phase phase.nii.gz --magnitude mag.nii.gz --output unwrapped.nii.gz
+```
+
+## Updating
+
+To update the app:
+
+```julia
+using Pkg
+Pkg.update("ROMEO")
+```
+
+Or:
+
+```
+pkg> app update ROMEO
+```
+
+## Uninstallation
+
+To remove the app:
+
+```julia
+using Pkg
+Pkg.rm("ROMEO", app=true)
+```
+
+Or:
+
+```
+pkg> app rm ROMEO
+```
+
+## Alternative: Direct Script Usage
+
+If you prefer not to use the app installation, you can still use the provided `romeo.jl` script as described in the main README.
