+= Collection Support
+
+Couchbase supports https://docs.couchbase.com/server/current/learn/data/scopes-and-collections.html[Scopes and Collections]. This section documents on how to use it with Spring Data Couchbase.
+
+The https://github.com/couchbaselabs/try-cb-spring[try-cb-spring] sample application is a working example of using Scopes and Collections in Spring Data Couchbase.
+
+The 2021 Couchbase Connect presentation on Collections in Spring Data can be found at https://www.youtube.com/watch?v=MrplTeEFItk[Presentation Only] and https://web.cvent.com/hub/events/1dce8283-986d-4de9-8368-94c98f60df01/sessions/9ee89a85-833c-4e0c-81b0-807864fa351b?goBackHref=%2Fevents%2F1dce8283-986d-4de9-8368-94c98f60df01%2Fsessions&goBackName=Add%2FView+Sessions&goBackTab=all[Presentation with Slide Deck]
+
+== Requirements
+
+ - Couchbase Server 7.0 or above.
+ - Spring Data Couchbase 4.3.1 or above.
+
+== Getting Started & Configuration
+
+
+=== Scope and Collection Specification
+There are several mechanisms of specifying scopes and collections, and these may be combined, or one mechanism may override another. 
+First some definitions for scopes and collections. An unspecified scope indicates that the default scope is to be used, likewise, an 
+unspecified collection indicates that the default collection is to be used.
+There are only three combinations of scopes and collections that are valid. (1) the default scope and the default collection; (2) the default
+scope and a non-default collection; and (3) a non-default scope and a non-default collection. It is not possible to have a non-default 
+scope and a default collection as non-default scopes do not contain a default collections, neither can one be created.
+
+A scope can be specified in the configuration:
+[source,java]
+----
+@Configuration
+static class Config extends AbstractCouchbaseConfiguration {
+
+    // Usual Setup
+    @Override public String getConnectionString() { /* ... */ }
+
+    // optionally specify the scope in the Configuration
+    @Override
+    protected String getScopeName() {
+        return "myScope"; // or a variable etc.;
+    }
+
+}
+----
+Scopes and Collections can be specified as annotations on entity classes and repositories:
+[source,java]
+----
+@Document
+@Scope("travel")
+@Collection("airport")
+public class Airport {...
+----
+
+[source,java]
+----
+@Scope("travel")
+@Collection("airport")
+public interface AirportRepository extends CouchbaseRepository<Airport, String> ...
+----
+
+Scopes and Collections can be specified on templates using the inScope(scopeName) and inCollection(collectionName) fluent APIs:
+[source,java]
+----
+List<Airport> airports = template.findByQuery(Airport.class).inScope("archived").all()
+----
+
+Scopes and Collections can be specified on repositories that extend DynamicProxyable using the withScope(scopeName) and withCollection(collectionName) APIs:
+[source,java]
+----
+public interface AirportRepository extends CouchbaseRepository<Airport, String>, DynamicProxyable<AirportRepository>{...}
+...
+List<Airport> airports = airportRepository.withScope("archived").findByName(iata);  
+----
+
+.The order of precedence is:
+. inScope()/inCollection() of the template fluent api
+. withScope()/withCollection() of the template/repository object
+. annotation of the repository method
+. annotation of the repository interface
+. annotation of the entity object
+. getScope() of the configuration
+
