rommapp/romm: README-based editorial guide

rommapp/romm describes itself in the README as "A beautiful, powerful, self-hosted rom manager and player.". This article keeps to facts that can be checked in the repository. Stars, forks, and promotional badges are signals of attention, not proof of quality. Under "README", the README says: A beautiful, powerful, self-hosted ROM manager and player.. That establishes the project's stated boundary, not a production test.

The README's "Features" section gives a useful starting point for deciding whether the project fits: Fetch custom artwork from [SteamGridDB][steamgriddb-api]. If that problem is not yours, popularity is a poor reason to adopt it. Project names, commands, and component names are kept as written so a reader can return to the primary source without guessing at terminology. Another checkable README item is: Scan and enhance your game library with metadata from [IGDB][igdb-api], [Screenscraper][screenscraper-api] and [MobyGames][mobygames-api]. It can shape a first test, but it does not replace testing in the intended environment.

The operating model is spread across sections such as "Preview". The source evidence includes: | 🖥 Desktop | 📱 Mobile | | :------------------------------------------------------------------------------------: | :-------------------------------------------------------------------------------------------------------------------------. This article does not turn missing architecture, performance, or security details into claims. A real deployment still needs a look at the repository layout, configuration files, and release history.

Start installation from the README's documented entry point. A command that can be checked in the source is: README 没有给出可直接复制的安装命令。 When the README contains no runnable command, this article does not invent one. Open its "Features" section and confirm system dependencies, default ports, and first-run initialization before using a public server.
