How to set up a charm project

To set up a charm project, create a directory for your charm, enter it, then run charmcraft init with the --profile flag followed by a suitable profile name (for machine charms: machine; for Kubernetes charms: kubernetes, simple, or flask-framework); that will create all the necessary files and even prepopulate them with useful content.

charmcraft init --profile <profile>

See sample session
$ mkdir my-flask-app-k8s
$ cd my-flask-app-k8s/
$ charmcraft init --profile flask-framework
Charmed operator package file and directory tree initialised.                                                                                                                                
Now edit the following package files to provide fundamental charm metadata                                                                                                                   
and other information:                                                                                                                                                                       
$ ls -R
charmcraft.yaml  requirements.txt  src


The command also allows you to not specify any profile (in that case you get the simple profile – a Kubernetes profile with lots of scaffolding, suitable for beginners) and has flags that you can use to specify a different directory to operate in, a charm name different from the name of the root directory, etc.
