+ cra.tw -- a link shortener for <a href="https://crates.io">crates.io</a>
+ </p>
+
+ <p>
+ i refer to npm packages a lot, and i've always found
+ npm.im, a url shortener so that you can type npm.im/mypackage instead of
+ npmjs.com/package/hello, very useful. the same thing goes for crates.io,
+ which is unwieldy to type, and i can never remember whether it's crates.io/crate or
+ crates.io/crates (it's the latter)
+ </p>
+
+ <p>cra.tw is very simple, the following will redirect:</p>
+
+ <p>
+ <a href="https://cra.tw/serde">cra.tw/serde</a> ---> <a href="https://crates.io/crates/serde">crates.io/crates/serde</a>
+ </p>
+
+ <p>
+ i hope it's useful to some other people as well!!
