1 | ## Using Cloudflare Workers for Discord embed support
2 |
3 | Requirements: Your own image host, on a domain that you control via [Cloudflare](https://www.cloudflare.com).
4 |
5 | Limitations: 100,000 requests per day (where the embed works).
6 |
7 | 1. Create a Cloudflare Worker: https://dash.cloudflare.com/sign-up/workers
8 | 2. Replace the script inside the worker with your desired script from this repo ([DiscordEmbed.js](DiscordEmbed.js) in this case).
9 | 3. Press "Save and Deploy".
10 | 4. Return to your dashboard, press "Workers", and then press "Add route".
11 | 5. Set the route to be where your images are hosted, for example: `i.example.com/*`.
12 | 6. Make sure to click "Request limit failure mode" and change it to "Fail open". This will allow your images to show, even if you exceed 100,000 requests.
13 | 7. Save & try it out.
