+# Customizer Integrations
 
 Boards adds multiple features to other HCL Connections applications via Connections Customizer. For details about what features this adds, see the [usage documentation](../../howto/connections/connections-ui.md).
 
 These features require your Connections envirionment to have Customiser installed. If you're new to Connections Customizer, here's a [great video introduction](https://www.youtube.com/watch?v=CvlpjIE-3TQ) and the [install documentation](https://help.hcltechsw.com/connections/v65/admin/install/cp_config_customizer_intro.html).

 Check the rules in your HTTP proxy that direct traffic to `mw-proxy` (customizer). See the [relevant section from the install documentation](https://help.hcltechsw.com/connections/v65/admin/install/cp_config_customizer_setup_nginx.html#:~:text=required%20Customizer%20URLs).
 
-  Huddo Boards features appear on every page in Connections where the Connections header appears. Your rules should match every URL that appears in the browser address bar. As mentioned in the documentation above, you may want to avoid matching some URLs (like API requests) for better performance.

-## Add Resources to `mw-proxy` Server
 1. Get a terminal session to your `mw-proxy` server. e.g. via `ssh`
 2. `mkdir /pv-connections/customizations/boards-extensions` if it doesn't exist.
 3. `cd /pv-connections/customizations/boards-extensions`
 4. In a web browser, download your custom Boards Extensions package from [Huddo Store](https://store.huddo.com/boards-extensions).
 5. Extract this package to `/pv-connections/customizations/boards-extensions`.
 6. `cat settings.js` and check that the "boardsURL" property has been set to the URL of your Boards deployment.

-2. Click _Save Changes_. You should see a notice about your changes being saved.
-3. **Important**: Connections customizer only supports one extension that customizes the Connections Navigation (`"type": "com.hcl.connections.nav"`). If you already have nav customizations, you must remove the "Tasks Nav Button" extension from `manifest.json` and merge it in to your existing nav customization. Otherwise only one of your nav customisations will take effect.

+## Disabling Extensions
 
-### Disabling Extensions
 Individual extensions within this package can be disabled using the _Extensions_ screen or by editing the JSON in the _Code Editor_. For example, if you're not using Connections 8, you may want to disable the extensions for Connections 8. There is no major issue in keeping these enabled. However, disabling extensions that are not compatible or needed will stop unnecessarily loading that extension's code.
 
 Keep in mind that any changes made will be discarded when following the _Updating_ steps below.
