+# Collaborative editing
+
+With Collaborative editing feature multiple users can work on the same content created in [[= product_name =]] simultaneously.
+This feature allows multiple users to work together on the same content item in real time, streamlining the content creation and review process.
+
+Users can invite both internal and external collaborators to a session, giving them access for editing or previewing.
+
+Additionaly, they can collaborate using a Real-time collaboration, an advanced part of the collaboration feature, to write and review content in a live mode thanks to CKEditor.
+Real-time collaboration syncs changes instantly and shows user avatars and colored tags to indicate who is editing each part of the content.
+
+This feature also introduces new dashboard tabs for managing shared drafts and joining collaboration sessions easily.

+description: Install the Collaborative editing LTS update.
+month_change: false
+---
+
+# Install Collaborative editing
+
+Collaborative editing feature is available as an LTS update to [[= product_name =]] starting with version v5.0 or higher, regardless of its edition.
+To use this feature you must first install the packages and configure them.
+
+## Install packages
+
+Run the following commands to install the packages:
+
+``` bash
+composer require ibexa/collaboration
+composer require ibexa/share
+composer require ibexa/fieldtype-richtext-rte
+```
+
+This command adds the new real-time editing functionality to the Rich Text field type.
+It also modifies the permission system to account for the new functionality.
+
+## Configure Collaborative editing
+
+Once the packages are installed, before you can start Collaborative editing feature, you must enable it by following these instructions.
+
+### Add tables to the database
+
+To add the tables to the database, run the following commands:
+
+``` bash
+php bin/console ibexa:doctrine:schema:dump-sql vendor/ibexa/collaboration/src/bundle/Resources/config/schema.yaml | mysql -u <username> -p <password> <database_name>
+php bin/console ibexa:doctrine:schema:dump-sql vendor/ibexa/share/src/bundle/Resources/config/schema.yaml | mysql -u <username> -p <password> <database_name>
+```
+
+### Modify the bundles file
+
+Then, in the `config/bundles.php` file, add the following code:
+
+``` php
+    <?php
+
+return [
+    // A lot of bundles…
+    Ibexa\Bundle\Collaboration\IbexaCollaborationBundle::class => ['all' => true],
+    Ibexa\Bundle\Share\IbexaShareBundle::class => ['all' => true],
+    Ibexa\Bundle\FieldTypeRichTextRTE\IbexaFieldTypeRichTextRTEBundle::class => ['all' => true],
+];
+```
+
+### Add migration file and execute migration
+
+Last step is to add migration file and execute migration with the following commands:
+
+``` bash
+php bin/console ibexa:migrations:import vendor/ibexa/collaboration/src/bundle/Resources/migrations/2025_08_26_10_14_shareable_user.yaml 
+php bin/console ibexa:migrations:migrate --file=2025_08_26_10_14_shareable_user.yaml
+```
+
+You can now restart you application and start [working with the Collaborative editing feature]([[= user_doc =]]/content_management/collaborative_editing/work_with_collaborative_editing/).
