## Instructions to load Yambo

First you need to load the module environment sourcing this file:

```{code-block} none
$ source /users/commun/seitsonen/HANAMI/setup-modules.txt
```

You can see the availabe packages with the following command:

```{code-block} none
$ module avail
------------------ /users/commun/seitsonen/HANAMI/sw/modules/app ------------------
miniforge/20251027  turbogenius/20251028   turborvb/git-20251030  yambo/5.3.0       
miniforge/20251028  turborvb/git-20251015  vesta/3.5.8            yambopy/20251029  
siesta/5.4.1        turborvb/git-20251028  vesta/3.90.5a          
```

Load Yambo through the module `yambo/5.3.0`

```{code-block} none
$ module load yambo/5.3.0
```

Check that the executable works by typing

```{code-block} none
$ yambo -h
```

which prints the help of the Yambo command-line interface.
