-#### Wrangler
+## Requirements
 
-To generate using [wrangler](https://github.com/cloudflare/wrangler)
+1. Your site need to be setup behind Cloudflare CDN.
+2. You need to setup InfluxDB with external access (make sure you have set [authentication](https://docs.influxdata.com/influxdb/v1.7/administration/authentication_and_authorization/#set-up-authentication))
+   1. Make sure InfluxDB is hosted under [supported port](https://blog.cloudflare.com/cloudflare-now-supporting-more-ports/) for Workers. Best option is 80 or 443.
+
+## How to use
+
+1. Install wrangler package
 
 ```
-wrangler generate projectname https://github.com/cloudflare/worker-template
+npm i @cloudflare/wrangler -g
 ```
 
-#### Serverless
+2. Copy example files
+
+```
+cp .env.example .env
+cp wrangler.toml.example wrangler.toml
+```
+
+3. Deploy your worker to a site with wrangler
+
+```
+wrangler publish --env production
+```
 
-To deploy using serverless add a [`serverless.yml`](https://serverless.com/framework/docs/providers/cloudflare/) file.
+4. (Optional) If you're using Grafana with InfluxDB, then you can import [example Dashboard](static/dashboard.json) from first screen.
