 ### Installation
 
 1. Clone the repository:
+
    ```bash
    git clone https://github.com/zhu327/miniflux-ai.git
    cd miniflux-ai
    ```
 
-2. Deploy to Cloudflare Workers:
+2. Create the Cloudflare Worker KV namespace:
+
+   ```bash
+   npx wrangler kv:namespace create entries
+   ```
+
+3. Update the `wrangler.toml` with the KV namespace ID from the previous command (under the `kv_namespaces` section).
+
+4. Deploy to Cloudflare Workers:
+
    ```bash
    npx wrangler deploy
    ```
 
+5. Add the Miniflux Webhook integration. Copy the URL for your deployed cloudflare worker and paste it in the Miniflux Settings page under the Webhook integration. After saving the settings, there will be a text input containing the webhook secret key. Copy it and set it as the `MINIFLUX_WEBHOOK_SECRET` secret (see Configuration section below).
+
+6. (Optional) To help differentiate the AI summary from the rest of the article text, add custom CSS styling for the `.ai-summary` block in your Miniflux settings (you may need to adjust the colors if you are not using a dark theme):
+
+```css
+.ai-summary {
+  background-color: #222;
+  border: 1px solid #aaa;
+  padding: 8px;
+  padding-top: 0px;
+}
+```
+
 ### Configuration
 
-The tool is configured using environment variables, which are set in the `wrangler.toml` file:
+The tool is configured using environment variables and [worker secrets](https://developers.cloudflare.com/workers/configuration/secrets/).
+
+See [this docs page on how to acquire your Cloudflare account ID and Workers API token](https://developers.cloudflare.com/workers-ai/get-started/rest-api/).
+
+You can set worker secrets with the command:
+
+```
+
+npx wrangler secret put SECRET_NAME
+
+```
+
+#### Secrets
 
 - `MINIFLUX_URL`: Your Miniflux instance URL.
 - `MINIFLUX_USERNAME`: Your Miniflux username.
 - `MINIFLUX_PASSWORD`: Your Miniflux password.
 - `OPENAI_URL`: The endpoint for the OpenAI API.
 - `OPENAI_TOKEN`: Your OpenAI API token.
+
+#### Environment Variables
+
+These environment variables can be set in the `wrangler.toml` file under the `[vars]` section:
+
 - `OPENAI_MODEL`: The model ID to use for generating summaries. We recommend using the `@cf/qwen/qwen1.5-14b-chat-awq` model for best results.
-- `WHITELIST_URL`: A comma-separated list of website URLs that should be summarized.
 
 ### Usage
 
-The tool runs as a scheduled Cloudflare Worker, querying for unread articles every 5 minutes. If an article is from a whitelisted site and does not contain code blocks, it generates a summary and updates the article.
+The worker listens for webhook requests from your Miniflux instance and when new entries are added it will store the entries in the Cloudflare KV store.
+
+The worker also runs a scheduled cron job, querying the KV store for queued entries every 5 minutes. If the entry content is 500 characters or longer, it generates an AI summary and updates the article to include the summary at the top of the content.
