rinse is not a search engine. It is a collection of specific commands meant to return instantly useful answers.
rinse is a fully open source project that anyone can contribute to.
There are 2 main reasons:
Contributions are highly encouraged.
The entire stack - front/back end code, infrastructure setup and deployment are all published openly. If you can think of ways to improve any of it, feel free to file an issue, or send a PR.
If you are not a software engineer, don't despair. Ideas on what to add next or how to make current commands better are welcome too.
