+### Pushing to cloudflare
+
+You can directly push this code to a cloudflare worker, but you still need a redirection io account to do so:
+
+ 1. You need to have wrangler installed: `cargo install wrangler`
+ 2. Login or configure your api token for cloudflare `wrangler login` or `wrangler config`
+ 3. Copy file `wrangler.toml.dist` to `wrangler.toml` and replace needed value
+ 4. Push your redirection io token as a secret value `wrangler secret put REDIRECTIONIO_TOKEN` and enter you redirection io project key when asked (available in your the instance panel of your project)
+ 5. Publish your worker: `wrangler publish`
