-Before resorting to crawling crates.io, you should first see if you are able to
-gather the information you need from the <a href='https://github.com/rust-lang/crates.io-index'>
-crates.io index</a>, which is a public git repository containing the majority
-of the information availble through our API.
-
-If the index does not have the information you need, we're also happy to
-discuss solutions to your needs that don't require you to crawl the registry.
-You can email us at <a href="mailto:help@crates.io">help@crates.io</a>.

-We allow our API and website to be crawled by commercial crawlers such as
-GoogleBot. At our discretion, we may choose to allow access to experimental
-crawlers, as long as they limit their request rate to 1 request per second or
-less.
-</p>
-
-<p>
-We also require all crawlers to provide a user-agent header that allows us to
-uniquely identify your bot. This allows us to more accurately monitor any
-impact your bot may have on our service. Providing a user agent that only
-identifies your HTTP client library (such as "<code>request/0.9.1</code>") increases the
-likelihood that we will block your traffic.
-
-It is recommended, but not required, to include contact information in your user
-agent. This allows us to contact you if we would like a change in your bot's
-behavior without having to block your traffic.
