+# Introduction
+
+This document describes the design of the replicator application for CouchDB
+4.x. The replicator will rely on `couch_jobs` for centralized scheduling and
+monitoring of replication jobs.
+
+## Abstract
+
+CouchDB replicator is the CouchDB application which runs replication jobs.
+Replication jobs can be created from documents in `_replicator` databases, or
+by `POST`-ing requests to the HTTP `/_replicate` endpoint. Previously, in
+CouchDB <= 3.x replication jobs were mapped to individual cluster nodes and a
+scheduler component would run up to `max_jobs` number of jobs at a time on each
+node. The new design proposes using `couch_jobs`, as described in
+[RFC](https://github.com/apache/couchdb-documentation/blob/master/rfcs/007-background-jobs.md),
+to have a central, FDB-based queue of replication jobs. `couch_jobs`
+application would manage job scheduling and coordination. The new design also
+proposes using heterogeneous node types as defined in
+[RFC](https://github.com/apache/couchdb-documentation/blob/master/rfcs/013-node-types.md)
+such that replication jobs will be created only on `api_frontend` nodes and run
+only on `replication` nodes.
+
+## Requirements Language
+
+The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD",
+"SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be
+interpreted as described in [RFC
+2119](https://www.rfc-editor.org/rfc/rfc2119.txt).
+
+## Terminology
+
+`_replicator` databases : A database that is either named `_replicator` or ends
+with the `/_replicator` suffix.

Review comment:
       Just double checking, is the suffix identifier `_replicator` or `/_replicator`?
