+= Adding a custom plug-in registry in an existing {prod-short} workspace
+
+
+The following section describes two methods of adding a custom plug-in registry in an existing {prod-short} workspace: 
+
+* xref:adding-a-custom-plug-in-registry-using-command-palette_{context}[Adding a custom plug-in registry using Command palette] - For adding a new custom plug-in registry quickly, with a use of text inputs from Command palette command. This method does not allow a user to edit already existing information, such as plug-in registry URL or name. 
+
+* xref:adding-a-custom-plug-in-registry-using-the-settings-file_{context}[Adding a custom plug-in registry using the `settings.json` file] - For adding a new custom plug-in registry and editing of the already existing entries.
+
+
+[id="adding-a-custom-plug-in-registry-using-command-palette_{context}"]
+== Adding a custom plug-in registry using Command Palette
+
+
+.Prerequisites
+
+* An instance of {prod-short}
+
+
+.Procedure
+
+. In the {prod-short} IDE, press kbd:[F1] to open the Command Palette, or navigate to *View -> Find Command* in the top menu.
++
+The *command palette* can be also activated by pressing kbd:[Ctrl+Shift+p] (or kbd:[Cmd+Shift+p] on macOS).
+
+. Enter the `Add Registry` command into the search box and pres kbd:[Enter] once filled.
+
+. Enter the registry name and registry URL in next two command prompts.
++
+* After adding a new plug-in registry, the list of plug-ins in the *Plug-ins* view is refreshed, and if the new plug-in registry is not valid, a user is notified by a warning message.
+
+
+
+[id="adding-a-custom-plug-in-registry-using-the-settings-file_{context}"]
+== Adding a custom plug-in registry using the `settings.json` file
+
+The following section describes the use of the main {prod-short} Settings menu to edit and add a new plug-in registry using the `settings.json` file.
+
+
+.Prerequisites
+
+* An instance of {prod-short}
+
+.Procedure
+
+. From the main {prod-short} screen, select *Open Preferences* by pressing kbd:[Ctrl+,]
+or using the gear wheel icon on the left bar.
+
+. Select *Che Plug-ins* and continue by *Edit in `setting.json`* link.
++
+The `setting.json` file is displayed.
+
+. Add a new plug-in registry using the `chePlugins.repositories` attribute as shown below:
++
+[source,yaml]
+----
+{
+“application.confirmExit”: “never”,
+“chePlugins.repositories”: {“test”: “++https++://test.com”}
+}
+----
+
+. Save the changes to add a custom plug-in registry in an existing {prod-short} workspace.
++
+* A newly added plug-in validation tool checks the correctness of URL values set in the `chePlugins.repositories` field of the `settings.json` file.
++
+* After adding a new plug-in registry, the list of plug-ins in the *Plug-ins* view is refreshed, and if the new plug-in registry is not valid, a user is notified by a warning message. This check is also functional for plug-ins added using the Command palette command `Add plugin registry`.
