Install python (3.6 and above would do fine, 3.9 is best), making sure python is in the path and that pip is enabled

1. Install docker desktop (might take a little more system ressources than local mode) and run it.
2. Run create_user.bat to... wait for it... create an admin account

Select the run_{XXX}.bat that corresponds to your installation type and leave it open if in local mode. Then, in a browser, go to http://localhost:2021 and login.

To add your ods file, there is a trombone icon in the donations page.

In the install directory, put your spreadsheet files in the files subfolder and run run_files.bat
