# Sponsorship Compiler Explorer is funded by sponsors: mostly individuals through Patreon, GitHub sponsors and PayPal one-off payments. There is potential for corporate sponsorship; though extremely limited due to the goal of making Compiler Explorer a mostly ad-free experience. Corporate sponsorship requests should be directed to [Matt](mailto:matt@godbolt.org), who has sole discretion on what kinds of sponsorship is appropriate. ## The sponsors.yaml format Sponsors are added by editing the `sponsors.yaml` file. The format is: ```yaml --- levels: - name: Level one description: A description of the first level of sponsors. class: css-class-to-apply # optional sponsors: - name: Displayed name img: url of an image # optional priority: 100 # optional, higher means shown first, else sorted by name url: link to navigate to if clicked # optional topIcon: true # optional, if true, show on the top of index.pug - name: Another... - Yet another # top level string treated as a {name: "Yet another"} - name: Level two description: The second level. sponsors: - bob - ian - joe ```
