+## Logos
+
+If your company is using Thanos in production, we'd love to showcase your company's logo on our page. Add yourself in [`website/data/sponsors.yml`](/website/data/sponsors.yml) like so:
+
+```yml
+- name: My Awesome Company
+  url: https://wwww.company.com
+  logo: company.png
+```
+
+Copy your company's logo in `website/static/logos`, and make sure it follows these rules:
+
+* Rectangle shape
+* Greyscale is prefered but color is fine
+* Keep it under 50KB
+
 ## Testing
 
 Every PR is building website and on success it shows the link to preview.
 
-Alternatively you can run `make web-serve` to serve and preview the website locally.
-
 ## Deployment.
 
 We use [Netlify](https://www.netlify.com/) for hosting. We are using Open Source license (PRO). Thanks Netlify for this!
