+# Gonum BLAS [![GoDoc](https://godoc.org/gonum.org/v1/gonum/blas?status.svg)](https://godoc.org/gonum.org/v1/gonum/blas)
+
+A collection of packages to provide BLAS functionality for the [Go programming
+language](http://golang.org)
+
+## Installation
+```sh
+  go get gonum.org/v1/gonum/blas/...
+```
+
+## Packages
+
+### blas
+
+Defines [BLAS API](http://www.netlib.org/blas/blast-forum/cinterface.pdf) split in several
+interfaces.
+
+### blas/gonum
+
+Go implementation of the BLAS API (incomplete, implements the `float32` and `float64` API).
+
+### blas/blas64 and blas/blas32
+
+Wrappers for an implementation of the double (i.e., `float64`) and single (`float32`)
+precision real parts of the BLAS API.
+
+```Go
+package main
+
+import (
+	"fmt"
+
+	"gonum.org/v1/gonum/blas/blas64"
+)
+
+func main() {
+	v := blas64.Vector{Inc: 1, Data: []float64{1, 1, 1}}
+	fmt.Println("v has length:", blas64.Nrm2(len(v.Data), v))
+}
+```
+
+### blas/cblas128 and blas/cblas64
+
+Wrappers for an implementation of the double (i.e., `complex128`) and single (`complex64`) 
+precision complex parts of the blas API.
+
+Currently blas/cblas64 and blas/cblas128 require gonum.org/v1/netlib/blas.
