# Apptainer SCI-F Apps
The Scientific Filesystem is well suited for Apptainer containers to allow you
to build a container that has multiple entrypoints, along with modular environments,
libraries, and executables. Here we will review the basic building and using of a
Apptainer container that implements SCIF. For more quick start tutorials, see
the [official documentation for SCIF](https://vsoch.github.io/scif/).
Build your image
```sh
sudo apptainer build cowsay.simg Apptainer.cowsay
```
What apps are installed?
```console
$ apptainer apps cowsay.simg
cowsay
fortune
lolcat
```
Ask for help for a specific app!
```console
$ apptainer help --app fortune cowsay.simg
fortune is the best app
```
Run a particular app
```console
$ apptainer run --app fortune cowsay.simg
When I reflect upon the number of disagreeable people who I know who have gone
to a better world, I am moved to lead a different life.
-- Mark Twain, "Pudd'nhead Wilson's Calendar"
```
Inspect an app
```console
$ apptainer inspect --app fortune cowsay.img
{
"SCIF_APPNAME": "fortune",
"SCIF_APPSIZE": "1MB"
}
```
