+JavaCPP Presets for Accelerate BLAS
+============================
+
+Introduction
+------------
+This directory contains the JavaCPP Presets module for Accelerate BLAS.
+
+
+Documentation
+-------------
+macOS has built-in BLAS library in Accelerate Framework.
+
+As a result, unlike other JavaCPP Presets, one does not need to build the native library using cppbuild.sh.
+
+
+Sample Usage
+------------
+Here is a simple example of BLAS matrix multiplication function `cblas_dgemm`:
+
+```
+import org.bytedeco.javacpp.accelerateblas;
+
+public class ExampleDGEMMrowmajor {
+
+    /* Auxiliary routine: printing a matrix */
+    static void print_matrix_rowmajor(String desc, int m, int n, double[] mat, int ldm) {
+        int i, j;
+        System.out.printf("\n %s\n", desc);
+
+        for (i = 0; i < m; i++) {
+            for (j = 0; j < n; j++) System.out.printf(" %6.2f", mat[i*ldm+j]);
+            System.out.printf("\n");
+        }
+    }
+
+    /* Auxiliary routine: printing a matrix */
+    static void print_matrix_colmajor(String desc, int m, int n, double[] mat, int ldm) {
+        int i, j;
+        System.out.printf("\n %s\n", desc);
+
+        for (i = 0; i < m; i++) {
+            for (j = 0; j < n; j++) System.out.printf(" %6.2f", mat[i+j*ldm]);
+            System.out.printf("\n");
+        }
+    }
+
+    /* Auxiliary routine: printing a vector of integers */
+    static void print_vector(String desc, int n, int[] vec) {
+        int j;
+        System.out.printf("\n %s\n", desc);
+        for (j = 0; j < n; j++) System.out.printf(" %6i", vec[j]);
+        System.out.printf("\n");
+    }
+
+    /* Main program */
+    public static void main(String[] args) {
+
+        /* Locals */
+        double[] A = {1, 2, 3, 4, 5, 6, 7, 8, 9};
+        double[] B = {1, 2, 3, 4, 5, 6, 7, 8, 9};
+        double[] C = {0, 0, 0, 0, 0, 0, 0, 0, 0};
+        int M, N;
+
+        /* Initialization */
+        M = 3;
+        N = 3;
+
+        /* Print Matrix */
+        print_matrix_rowmajor("Matrix A", M, N, A, M);
+
+        /* Print Matrix */
+        print_matrix_rowmajor("Matrix B", M, N, B, M);
+
+        /* Print Matrix */
+        print_matrix_rowmajor("Matrix C", M, N, C, M);
+        System.out.println();
+
+        /* Executable statements */
+        System.out.println("cblas_dgemm Results: A * B = C");
+        accelerateblas.cblas_dgemm(accelerateblas.CblasRowMajor, accelerateblas.CblasNoTrans, accelerateblas.CblasNoTrans, M, N, M, 1, A, M, B, M, 1, C, M);
+
+        /* Print Result Matrix */
+        print_matrix_rowmajor("Matrix C", M, N, C, M);
+
+        System.out.println();
+        System.exit(0);
+    }
+}
+```
+
+Using Gradle
+
+`build.gradle`
+
+```
+buildscript {
+    ext {
+        javacpp_version = "1.3.3-SNAPSHOT"
+    }
+}
+
+apply plugin: "application"
+
+repositories {
+    mavenLocal()
+    mavenCentral()
+}
+
+dependencies {
+    compile("org.bytedeco:javacpp:${javacpp_version}")
+    compile("org.bytedeco.javacpp-presets:accelerateblas:10.12.5-${javacpp_version}")
+    compile("org.bytedeco.javacpp-presets:accelerateblas:10.12.5-${javacpp_version}:macosx-x86_64")
+}
+
+run {
+    mainClassName = "ExampleDGEMMrowmajor"
+}
+```
+
+Run the example:
+```
+./gradlew run
+```
+
+will print out
+```
