Spoolman/README.md
Donkie c781869d09 Refresh the README screenshot and note the legacy-client rollback
The screenshot was the 2023 React client -- a different application from
the one a new visitor now installs. The replacement is client_v2's
library with a spool's details open beside it, which is where anyone
using Spoolman spends their time, and it lives in the repo rather than
on user-content URLs so it can be regenerated with the client.

The feature list gains search/group/filter, which client_v2 makes a
first-class part of the library rather than per-column table filters.

Installation now mentions SPOOLMAN_LEGACY_CLIENT. Someone whose setup
the new client misbehaves on will look here before .env.example, and
the useful thing to know is that both clients ship in every release and
share the API, so falling back costs nothing.

Keep track of your inventory of 3D-printer filament spools.

Spoolman is a self-hosted web service designed to help you efficiently manage your 3D printer filament spools and monitor their usage. It acts as a centralized database that seamlessly integrates with popular 3D printing software like OctoPrint and Klipper/Moonraker. When connected, it automatically updates spool weights as printing progresses, giving you real-time insights into filament usage.

Installation

Please see the Installation page on the Wiki for details how to install Spoolman.

If the new client misbehaves on your setup, set SPOOLMAN_LEGACY_CLIENT=TRUE to go back to the previous one. Both ship in every release and talk to the same API, so your data is untouched either way — but please report the problem so it can be fixed.
