# Task Lists

## How Task Lists Work

Wrangle's task list functionality assigns people to complete a checklist of one or more tasks.

## When Task Lists Are Considered Complete

A task list is composed of one or more tasks. The overall task list is considered complete when all of its tasks are marked as complete.

## Launching One-Off Task Lists

Most task lists are launched via a [Wrangle workflow](https://docs.wrangle.io/workflows/designing-a-workflow/broken-reference) for a recurring use case. But you can also start a one-off task list for work that comes up from time-to-time. For example, if you're working on a small project (outside of a workflow) you could create a one-off task list to assign different tasks to your colleagues.

You can launch a one-off task list in one of many ways:

* There's a button on the [Wrangle App Home page](https://docs.wrangle.io/best-practices/wrangle-app-home)
* You can use Slack's search bar and look for "Start a Task List with Wrangle"
* You can use the Shortcuts menu by clicking the ➕ icon in the reply box and searching for "Start a Task List with Wrangle." Instead of clicking the icon, you can also type "/" in the reply box as well.

## Editing Task Lists In Progress

If a task list has not been completed, you can edit any incomplete tasks. You can add/delete tasks, rename them, and change who is assigned to each. You can't remove tasks that are marked as complete.

Not everyone can edit an in-progress task list. 

If the task list was created by a [workflow](https://docs.wrangle.io/workflows/designing-a-workflow/broken-reference), it can only be edited by people assigned to a task or by the Workflow's Admins.

If the task list is a [one-off task list](#launching-one-off-task-lists), it can only be edited by people assigned to it, or to its creator.
