# Contribution Guidelines
This is the home of Shields.io, home to the badge design specification, API documentation, and server code for Badges as a Service.
We invite participation through [GitHub Issues][], which we use much like a discussion forum. This repository should only contain non-implementation specific topics: specifications, design, and the web site.
## This implementation
Please see [INSTALL.md][] for information on how to start contributing code to
shields.io.
[INSTALL.md]: ./INSTALL.md
Note that the root gets redirected to <http://shields.io>.
For testing purposes, you can go to `http://localhost/try.html`.
You should modify that file. The "real" root, `http://localhost/index.html`,
gets generated from the `try.html` file with a `make website`.
## Ground rules
- The left-hand side of a badge should not advertize. It should be a noun
describing succinctly the meaning of the right-hand-side data.
- New query parameters (such as `?label=` or `?style=`) should apply to any
requested badge. They must be registered in the cache (see `LruCache` in
`server.js`).
- The format of new badges should be of the form
`/VENDOR/SUBVENDOR-BADGE-SPECIFIC/PARAMETERS.format`. For instance,
`https://img.shields.io/gitter/room/nwjs/nw.js.svg`. The vendor is gitter, the
badge is for rooms, the parameter is nwjs/nw.js, and the format is svg.
## Implementations
The main implementation, available at <http://shields.io>, has its code located in this repository.
Other systems that produce badges following the same design, hosted elsewhere, are listed below.
