+:description: This page describes how to load plugins to a Neo4j deployment.
+
+Neo4j distributions come bundled with a range of pre-installed products, such as Graph Data Science library, Bloom, and Ops Manager, which can be used to extend the Neo4j capabilities.
+The JAR files for these products are located in the _product_ and _labs_ folders and can be installed as plugins.
+
+If you want to use your own plugins, ensure that you add them to the designated _plugins_ directory.
+This directory serves as the central location where Neo4j looks for and loads the plugins at startup. 
+
+[NOTE]
+====
+Bloom and GDS Enterprise require a license activation key to become available to the user within Neo4j.
+Reach out to your Neo4j account representative or request a representative to link:https://neo4j.com/contact-us/#sales-inquiry[contact you].
+====
+
+The following plugins are supported:

+== Install and configure plugins 
+
+Here are the steps to enable the plugins:
+
+. Move or copy the plugins (_.jar files_) from _<NEO4J_HOME>/products_ and _<NEO4J_HOME>/labs_ to the _<NEO4J_HOME>/plugins_ directory.
+See the table in xref:configuration/file-locations/[File locations] for more information.
+
+. Add the following lines in _$NEO4J_HOME/conf/neo4j.conf_:
++
+[source, properties]
+----
+# to enable GDS:
+
+* dbms.security.procedures.unrestricted=gds.*
+* dbms.security.procedures.allowlist=gds.*
+* gds.enterprise.license_file=/path/to/my/license/keyfile
+
+
+#  to enable Bloom:
+
+* dbms.security.procedures.unrestricted=bloom.*
+* dbms.bloom.license_file=/path/to/my/license/keyfile
+
+
+#  to enable both GDS and Bloom:
+
+* dbms.security.procedures.unrestricted=gds.*,bloom.*
+* dbms.security.procedures.allowlist=gds.*
+* gds.enterprise.license_file=/path/to/my/license/keyfile
+* dbms.bloom.license_file=/path/to/my/license/keyfile
+----
+. Install the plugins.

+Refer to link:https://neo4j.com/docs/bloom-user-guide/current/bloom-installation/[Bloom documentation], link:https://neo4j.com/docs/graph-data-science/current/installation/[GDS documentation], and  https://neo4j.com/docs/ops-manager/current[Neo4j Ops Manager documentation] for more details on how to install them.
+
+[NOTE]
+====
+All installed plugins will automatically be loaded every time Neo4j is started.
+Because of that, the number of plugins may impact the startup time. 
+Install only the necessary plugins to avoid performance issues.
