README badges
If your tool is listed on devxtools.dev, you can add a badge to your README or docs that links to your listing. It's optional, it's free, and nobody will chase you about it.
What the badge means
The badge says your tool is listed in the devxtools.dev catalog and that we've reviewed the listing against official sources, with a dated check. That's all it means.
It doesn't mean that we endorse or recommend the tool over alternatives, that anyone paid for the listing (nobody can), or that the tool won a comparison.

- Only for listed tools. Use the badge only if your tool has a live listing at the URL it links to.
- Link to your listing. Keep the link pointing at your devxtools.dev listing page, not the home page or somewhere else.
- Don't modify it. Don't change the badge's wording, colours or logo.
- It's optional, and it has no effect. Adding the badge, or not adding it, doesn't affect your listing, its position, or any comparison or verdict.
