+-**WARNING**: this crate only supports the most recent nightly Rust toolchain.
++**WARNING**: this crate only supports the most recent nightly Rust toolchain
++and will be superceded by [stdsimd](https://github.com/rust-lang/stdsimd).
+ 
+ ## Documentation
+ 
+ * [API docs (`master` branch)][master_docs]
+ * [Performance guide][perf_guide]
+-* [API docs (`docs.rs`)][docs.rs]: **CURRENTLY DOWN** due to
+-  https://github.com/rust-lang-nursery/packed_simd/issues/110
++* [API docs (`docs.rs`)][docs.rs]
+ * [RFC2366 `std::simd`][rfc2366]: - contains motivation, design rationale,
+   discussion, etc.
+ 
+ ## Examples
+ 
+ Most of the examples come with both a scalar and a vectorized implementation.
+ 
+ * [`aobench`](https://github.com/rust-lang-nursery/packed_simd/tree/master/examples/aobench)
+ * [`fannkuch_redux`](https://github.com/rust-lang-nursery/packed_simd/tree/master/examples/fannkuch_redux)
+ * [`matrix inverse`](https://github.com/rust-lang-nursery/packed_simd/tree/master/examples/matrix_inverse)
+ * [`mandelbrot`](https://github.com/rust-lang-nursery/packed_simd/tree/master/examples/mandelbrot)
+ * [`n-body`](https://github.com/rust-lang-nursery/packed_simd/tree/master/examples/nbody)
+ * [`options_pricing`](https://github.com/rust-lang-nursery/packed_simd/tree/master/examples/options_pricing)
+ * [`spectral_norm`](https://github.com/rust-lang-nursery/packed_simd/tree/master/examples/spectral_norm)
+ * [`triangle transform`](https://github.com/rust-lang-nursery/packed_simd/tree/master/examples/triangle_xform)
+ * [`stencil`](https://github.com/rust-lang-nursery/packed_simd/tree/master/examples/stencil)
+ * [`vector dot product`](https://github.com/rust-lang-nursery/packed_simd/tree/master/examples/dot_product)
+ 
+ ## Cargo features
+ 
+ * `into_bits` (default: disabled): enables `FromBits`/`IntoBits` trait
+   implementations for the vector types. These allow reinterpreting the bits of a
+   vector type as those of another vector type safely by just using the
+   `.into_bits()` method.
+ 
+-* `core_arch` (default: disabled): enable this feature to recompile `core::arch`
+-  for the target-features enabled. `packed_simd` includes optimizations for some
+-  target feature combinations that are enabled by this feature. Note, however,
+-  that this is an unstable dependency, that rustc might break at any time.
+-
+-* `sleef-sys` (default: disabled - `x86_64` only): internally uses the [SLEEF]
+-  short-vector math library when profitable via the [`sleef-sys`][sleef_sys]
+-  crate. [SLEEF] is licensed under the [Boost Software License
+-  v1.0][boost_license], an extremely permissive license, and can be statically
+-  linked without issues.
+-
+ ## Performance
+ 
+ The following [ISPC] examples are also part of `packed_simd`'s
+ [`examples/`](https://github.com/rust-lang-nursery/packed_simd/tree/master/examples/)
+ directory, where `packed_simd`+[`rayon`][rayon] are used to emulate [ISPC]'s
+ Single-Program-Multiple-Data (SPMD) programming model. The performance results
+ on different hardware is shown in the `readme.md` of each example. The following
+ table summarizes the performance ranges, where `+` means speed-up and `-`
+ slowdown:
+ 
+ * `aobench`: `[-1.02x, +1.53x]`,
+ * `stencil`: `[+1.06x, +1.72x]`,
+ * `mandelbrot`: `[-1.74x, +1.2x]`,
+ * `options_pricing`:
+    * `black_scholes`: `+1.0x`
+    * `binomial_put`: `+1.4x`
+ 
+  While SPMD is not the intended use case for `packed_simd`, it is possible to
+  combine the library with [`rayon`][rayon] to poorly emulate [ISPC]'s SPMD programming
+  model in Rust. Writing performant code is not as straightforward as with
+  [ISPC], but with some care (e.g. see the [Performance Guide][perf_guide]) one
+  can easily match and often out-perform [ISPC]'s "default performance".
+ 
+ ## Platform support
+ 
+-The following table describes the supported platforms: `build` shows whether the
+-library compiles without issues for a given target, while `run` shows whether
+-the full testsuite passes on the target.
