Download and install the [TinyMCE Community edition](/get-tiny/) to get started. Signing up for a free API key provides entitlements to the premium [Image Editing](../editimage/) plugin. A Tiny Cloud image proxy server must already be configured. Premium plugins can be purchased at any time once the API key has been set up. ## Step 1: Insert the custom script tag into the webpage Add the following script in the webpage once the script tag to load TinyMCE has been specified. Be sure to substitute 'no-api-key' with your api key. ```js ``` ## Step 2: Specify purchased TinyMCE plugins and toolbar buttons > **Note:** It may take up to 30 minutes for the purchased plugin to be available to TinyMCE. Clear the browser’s cache. Extend the [TinyMCE configuration](../basic-setup/) to include any additional purchased plugins and associated toolbar and menu items. For the enablement guide for each plugin, refer to [Premium plugins](../plugins/#premium-plugins). > **Note:** Configuration of the following options occurs automatically when using the Tiny Cloud: > > - `editimage_cors_hosts` > - `editimage_proxy_service_url` > - `export_image_cors_hosts` > - `export_image_proxy_service_url` > - `linkchecker_service_url` > - `mediaembed_service_url` > - `spellchecker_rpc_url` > - `autocorrect_service_url` The following is a complete example, where: - The Tiny Cloud `API key` has the value `no-api-key`. - The Tiny Cloud has the [Spell Checker](../introduction-to-tiny-spellchecker/) plugin enabled. ```js ``` ## Step 3: Forward proxy and firewall configuration If the network has a firewall or forward proxy that controls access to the internet, ensure that the following URLs are accessible: - All URLs where the editor is deployed. - All URLs where the plugins are deployed. - `*.tiny.cloud` — covers all Tiny Cloud services, including the image proxy, link checker, spell checker, AI API, and document converters. Ensure the `tiny-api-key` and `tinymce-api-key` headers are retained while requesting the above URLs. For the full list of Tiny Cloud service domains and required headers, see [Firewall and proxy allowlisting](../tinymce-and-csp/#firewall-and-proxy-allowlisting).
