+# Trilium Notes
+
+## Trilium è in manutenzione - vedi i dettagli in https://github.com/zadam/trilium/issues/4620
+
+Le discussioni preliminari sull'organizzazione si stanno svolgendo in [Trilium Next discussions](https://github.com/orgs/TriliumNext/discussions). 
+
+[![Join the chat at https://gitter.im/trilium-notes/Lobby](https://badges.gitter.im/trilium-notes/Lobby.svg)](https://gitter.im/trilium-notes/Lobby?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge) [English](https://github.com/zadam/trilium/blob/master/README.md) | [Chinese](https://github.com/zadam/trilium/blob/master/README-ZH_CN.md) | [Russian](https://github.com/zadam/trilium/blob/master/README.ru.md) | [Japanese](https://github.com/zadam/trilium/blob/master/README.ja.md) | [Italian](https://github.com/zadam/trilium/blob/master/README.it.md)
+
+
+Trilium Notes è un'applicazione per appunti ad organizzazione gerarchica, studiata per la costruzione di archivi di conoscenza personali di grandi dimensioni.
+
+Vedi [fotografie](https://github.com/zadam/trilium/wiki/Screenshot-tour) per una panoramica veloce:
+
+<a href="https://github.com/zadam/trilium/wiki/Screenshot-tour"><img src="https://raw.githubusercontent.com/wiki/zadam/trilium/images/screenshot.png" alt="Trilium Screenshot" width="1000"></a>
+
+L'Ucraina si sta difendendo dall'aggressione russa, considera [donare all'esercito ucraino o a organizzazioni umanitarie](https://standforukraine.com/).

+</p>
+
+## 🎁 Funzionalità
+
+
+* Gli appunti possono essere organizzati in un albero di profondità arbitraria. Un singolo appunto può essere collocato in più posti nell'albero (vedi [clonazione](https://github.com/zadam/trilium/wiki/Cloning-notes))
+* Ricco editor visuale (WYSIWYG), con supporto -tra l'altro- per tabelle, immagini ed [espressioni matematiche](https://github.com/zadam/trilium/wiki/Text-notes#math-support) e con [formattazione automatica](https://github.com/zadam/trilium/wiki/Text-notes#autoformat) per markdown
+* Supporto per la modifica di [appunti con codice sorgente](https://github.com/zadam/trilium/wiki/Code-notes), con evidenziazione della sintassi
+* [Navigazione veloce](https://github.com/zadam/trilium/wiki/Note-navigation) tra gli appunti, ricerca testuale completa e [fissaggio degli appunti](https://github.com/zadam/trilium/wiki/Note-hoisting)
+* Supporto integrato ed automatico per le [revisioni degli appunti](https://github.com/zadam/trilium/wiki/Note-revisions)
+* Gli [attributi](https://github.com/zadam/trilium/wiki/Attributes) degli appunti possono essere utilizzati per l'organizzazione, per l'interrogazione e per lo scripting avanzato (prorgrammazione).
+* [Sincronizzazione](https://github.com/zadam/trilium/wiki/Synchronization) con un server di sincronizzazione auto-ospitato
+  * c'è un [servizio di terze parti per ospitare server di sincronizzazione](https://trilium.cc/paid-hosting)
+* [Condivisione](https://github.com/zadam/trilium/wiki/Sharing)  (pubblicazione) di appunti sull'internet pubblico
+* Robusta [crittografia](https://github.com/zadam/trilium/wiki/Protected-notes) configurabile singolarmente per ogni appunto
+* Disegno di diagrammi con Excalidraw (tipo di appunto "canvas")
+* [Mappe relazionali](https://github.com/zadam/trilium/wiki/Relation-map) e [mappe di collegamenti](https://github.com/zadam/trilium/wiki/Link-map) per visualizzare gli appunti e le loro relazioni
+* [Scripting](https://github.com/zadam/trilium/wiki/Scripts) - vedi [Esempi avanzati](https://github.com/zadam/trilium/wiki/Advanced-showcases)
+* [API REST](https://github.com/zadam/trilium/wiki/ETAPI) per l'automazione
+* Si adatta bene sia in termini di usabilità che di prestazioni fino ad oltre 100 000 appunti
+* Interfaccia utente ottimizzata per il [mobile](https://github.com/zadam/trilium/wiki/Mobile-frontend) (smartphone e tablet)
+* [Tema Notturno](https://github.com/zadam/trilium/wiki/Themes)
+* Supporto per importazione ed esportazione da e per [Evernote](https://github.com/zadam/trilium/wiki/Evernote-import) e [Markdown import](https://github.com/zadam/trilium/wiki/Markdown)
+* [Web Clipper](https://github.com/zadam/trilium/wiki/Web-clipper) per il salvataggio facile di contenuti web
+
+
+Dai un'occhiata a [awesome-trilium](https://github.com/Nriver/awesome-trilium) per temi, script, plugin e altro di terze parti.
+
+## 🏗 Rilasci
+
+
+Trilium è fornito come applicazione desktop (Linux e Windows) o come applicazione web ospitata sul tuo server (Linux). La versione desktop per Mac OS è disponibile, ma [non è supportata](https://github.com/zadam/trilium/wiki/FAQ#mac-os-support).
+
+* Se vuoi usare Trilium sul tuo desktop, scarica il rilascio binario per la tua piattaforma dall'[ultimo rilascio](https://github.com/zadam/trilium/releases/latest), decomprimi l'archivio e avvia l'eseguibile ```trilium```.
+* Se vuoi installare Trilium su un server, segui [questa pagina](https://github.com/zadam/trilium/wiki/Server-installation).
+  * Per ora solo Chrome e Firefox sono i browser supportati (testati).
+
+Trilium è anche disponibile su Flatpak:
