+== Implement custom seed providers
+
+The _Seed from URI_ feature provides the ability to dynamically discover additional seed provider implementations from the class path.
+
+Seed providers should be implemented in Java and this guide provides instructions on how to do this using Maven as the build tool.
+
+=== Set up a Maven project
+
+Include this dependency to build against the Neo4j-provided API:
+
+[source, xml, subs="attributes, specialcharacters"]
+----
+<dependency>
+   <groupId>com.neo4j</groupId>
+   <artifactId>neo4j-dbms-api</artifactId>
+   <version>${project.version}</version>
+   <scope>compile</scope>
+</dependency>
+----
+
+=== Implement Java class
+
+[source, java]
+----
+import com.neo4j.dbms.seeding.ParsedSeedProviderConfig;
+import com.neo4j.dbms.seeding.SeedProvider;
+
+public class CustomSeedProvider extends SeedProvider {
+
+	public boolean matches(String uri) {
+   		// return true if uri is supported by this
+      // provider
+  }
+
+public Path download(
+     	String uri,
+      Optional<String> credentials,
+      Optional<String> config,
+      Path destinationFolder ) throws Exception {
+      // This method should obtain the downloaded in an
+      // implementation specific way and copy it to a
+      // file within the destinationFolder directory.
+  }
+}
+----
+
+To implement the custom seed provider, you must implement two methods.
+One method to match the URIs it can manage and one to download backups or dumps from the given URI.
+
+Typically, the match method uses the URI scheme (the part specified before the first colon) to determine whether it can support the given URI or not.
+For example, `file`, `http`, `https` etc.
+
+The download method should implement a scheme-specific way to obtain the backup or dump and place it into a file in the supplied destination folder.
+It should then return the path of the created file.
+
+Both credentials and configurations are passed through from options specified in the `CREATE DATABASE` command.
+`ParsedSeedProviderConfig` provides a convenient way to parse and access the comma-separated configuration string.
+
+=== Deploy
+
+Build a jar file from Maven and place this onto the Neo4j classpath.
+
+The jar must include a META-INF file to enable discovery of the providers with the path:
+
+[source, none]
+----
+/META_INF/services/com.neo4j.dbms.seeding.SeedProvider
+----
+
+It should be a plain text file with one line for each provider contained within the jar, the line should contain the fully qualified name of the provider class.
