+# cpuid
+Package cpuid provides information about the CPU running the current program.
+
+CPU features are detected on startup, and kept for fast access through the life of the application.
+Currently x86 / x64 (AMD64/i386) and ARM (ARM64) is supported, and no external C (cgo) code is used, which should make the library very easy to use.
+
+You can access the CPU information by accessing the shared CPU variable of the cpuid library.

+
+# usage
+
+The `cpuid.CPU` provides access to CPU features. Use `cpuid.CPU.Supports()` to check for CPU features.
+A faster `cpuid.CPU.Has()` is provided which will usually be inlined by the gc compiler.  
+
+Note that for some cpu/os combinations some features will not be detected.
+`amd64` has rather good support and should work reliably on all platforms.
+
+Note that hypervisors may not pass through all CPU features.
+
+## arm64 feature detection
+
+Not all operating systems provide ARM features directly 
+and there is no safe way to do so for the rest.
+
+Currently `arm64/linux` and `arm64/freebsd` should be quite reliable. 
+`arm64/darwin` adds features expected from the M1 processor, but a lot remains undetected.
+
+A `DetectARM()` can be used if you are able to control your deployment,
+it will detect CPU features, but may crash if the OS doesn't intercept the calls.
+A `-cpu.arm` flag for detecting unsafe ARM features can be added. See below.
+ 
+Note that currently only features are detected on ARM, 
+no additional information is currently available. 
+
+## flags
+
+It is possible to add flags that affects cpu detection.
+
+For this the `Flags()` command is provided.
+
+This must be called *before* `flag.Parse()` AND after the flags have been parsed `Detect()` must be called.
+
+This means that any detection used in `init()` functions will not contain these flags.
+
+Example:
+
+```Go
+package main
+
+import (
+	"flag"
+	"fmt"
+	"strings"
+
+	"github.com/klauspost/cpuid/v2"
+)
+
+func main() {
+	cpuid.Flags()
+	flag.Parse()
+	cpuid.Detect()
+
+	// Test if we have these specific features:
+	if cpuid.CPU.Supports(cpuid.SSE, cpuid.SSE2) {
+		fmt.Println("We have Streaming SIMD 2 Extensions")
+	}
+}
