# Introduction

The Review Platform is where your team works the reviews your playbooks create. It puts every review in a queue, orders the queue by how urgent each review is, and hands out the next review when a reviewer asks for one.

## What it does

* **Queues by review kind.** A playbook raises a review of a given kind. The kind sets the review's SLA and base priority, and the queue bound to that kind decides which reviewers work it.
* **Pull-based assignment.** A reviewer clicks **Pull next review** and gets the review at the top of the queue's order. A reviewer can also assign an unassigned review to themselves from the queue's list.
* **Priority from SLA, base priority, and age.** Each queue sorts by due date, by base priority, by creation time, or by a hybrid that raises a review's priority as its deadline approaches.
* **Queue counts.** For every queue, how many reviews it holds, how many are assigned and in progress, and how many are overdue or due within 1, 6, or 12 hours.

## Where to go next

If you are setting the platform up, start with [Getting started](/articles/guides/manual-review-platform-getting-started) and keep [Core concepts](/articles/guides/manual-review-platform-core-concepts) open next to it for review kinds, queues, and prioritization. [Reviewers and teams](/articles/guides/manual-review-platform-review-agents-teams) is about who can pull from which queue, and [Reviewer workflow](/articles/guides/manual-review-platform-reviewer-workflow) about how a reviewer gets and finishes a review. For the counts that tell you when to move reviewers, see [Operations management](/articles/guides/manual-review-platform-operations-management); for how playbooks create reviews in the first place, [Integration with playbooks](/articles/guides/manual-review-platform-integration-workflows).
