Serving static files


I would like to save some statics files, to be used on my dashboards.
For example, an image with my home plans, to place sensors on it.

I did not find any www folder. So, I created mine.
My file is now located on /config/www/home.png.
But I can’t access it.,, …

I think rights are fine, as all configuration files are root:root.

➜  www ls -al 
total 36
drwxr-xr-x 2 root root  4096 Jul 21 21:34 .
drwxr-xr-x 9 root root  4096 Jul 21 21:22 ..
-rw-r--r-- 1 root root 27564 Jul 21 21:34 home.png

What am I missing ?

Thanks for your help.
Regards !

This is the documentation I used.
But I missed an important part :

If you’ve had to create the www/ folder for the first time, you’ll need to restart Home Assistant.

Problem solved, thank you.
