# Understand a Unit and its sync behavior

A Unit is the main place where work, context, collaboration, Orbit, and Lenses come together.

## Unit header

The header can show the title, status, assignee or owner, date, participants, priority, and additional controls. Work Units also show their source identifier, such as a Jira issue key.

## Description and tabs

The description explains the Unit. Tabs can include Attachments, Relationships, and Activity. Available Unit tools can include time tracking, Estimations, Documents, and Diagrams.

## What can sync

For supported Work Units, status and assignee can sync where the provider exposes them. Estimate, time, comments, attachments, and relationships differ by provider and feature.

Current examples:

* Jira and Azure DevOps support sprint, status, and type sync rules.
* Linear supports cycle and status rules.
* monday.com supports group and status rules.
* GitHub Issues, Trello, Todoist, and Wrike currently use hand-pick import.
* Provider comments can contribute Lens signals for Jira, Azure DevOps, Linear, monday.com, and Wrike.

Documents, Diagrams, and Quely Threads remain in Quely. Do not assume a Quely Thread becomes a provider comment.

## Context Units

A Context Unit is native to Quely and does not have an external task identifier. It can reference several connected sources but belongs to one Space.

## If information looks wrong

* Confirm whether the Unit is Work or Context.
* Confirm the source connection is active.
* Check the source tool for the current field value.
* Refresh or wait for the supported synchronization process.
* Contact support if changes remain inconsistent.
