 ## Installation
 
-The Rust compiler is slightly unusual in that it is written in Rust and
-therefore must be built by a precompiled "snapshot" version of itself (made in
-an earlier state of development). As such, source builds require that:
+The Rust compiler currently must be built from a [tarball], unless you

+Since the Rust compiler is written in Rust, it must be built by
+a precompiled "snapshot" version of itself (made in an earlier state

-* You can at least execute snapshot binaries of one of the forms we offer
-  them in. Currently we build and test snapshots on:
+Snapshot binaries are currently built and tested on several platforms:
 
-  * Windows (7, server 2008 r2) x86 only
-  * Linux 2.6.x (various distributions) x86 and x86-64

-environments that are most likely to work. Further platforms will be added to
-the list in the future via cross-compilation.
