-## Description
-
-Package bitset implements bitsets, a mapping between non-negative integers and boolean values.
-It should be more efficient than map[uint] bool.
-
-It provides methods for setting, clearing, flipping, and testing individual integers.
-
-But it also provides set intersection, union, difference, complement, and symmetric operations, as well as tests to check whether any, all, or no bits are set, and querying a bitset's current length and number of positive bits.
-
-BitSets are expanded to the size of the largest set bit; the memory allocation is approximately Max bits, where Max is the largest set bit. BitSets are never shrunk. On creation, a hint can be given for the number of bits that will be used.
-
-Many of the methods, including Set, Clear, and Flip, return a BitSet pointer, which allows for chaining.
-
-### Example use:
-
-```go
-package main
-
-import (
-	"fmt"
-	"math/rand"
-
-	"github.com/bits-and-blooms/bitset"
-)
-
-func main() {
-	fmt.Printf("Hello from BitSet!\n")
-	var b bitset.BitSet
-	// play some Go Fish
-	for i := 0; i < 100; i++ {
-		card1 := uint(rand.Intn(52))
-		card2 := uint(rand.Intn(52))
-		b.Set(card1)
-		if b.Test(card2) {
-			fmt.Println("Go Fish!")
-		}
-		b.Clear(card1)
-	}
-
-	// Chaining
-	b.Set(10).Set(11)
-
-	for i, e := b.NextSet(0); e; i, e = b.NextSet(i + 1) {
-		fmt.Println("The following bit is set:", i)
-	}
-	if b.Intersection(bitset.New(100).Set(10)).Count() == 1 {
-		fmt.Println("Intersection works.")
-	} else {
-		fmt.Println("Intersection doesn't work???")
-	}
-}
-```
-
-As an alternative to BitSets, one should check out the 'big' package, which provides a (less set-theoretical) view of bitsets.
-
-Package documentation is at: https://pkg.go.dev/github.com/bits-and-blooms/bitset?tab=doc
-
-## Memory Usage
-
-The memory usage of a bitset using N bits is at least N/8 bytes. The number of bits in a bitset is at least as large as one plus the greatest bit index you have accessed. Thus it is possible to run out of memory while using a bitset. If you have lots of bits, you might prefer compressed bitsets, like the [Roaring bitmaps](http://roaringbitmap.org) and its [Go implementation](https://github.com/RoaringBitmap/roaring).
-
-## Implementation Note
-
-Go 1.9 introduced a native `math/bits` library. We provide backward compatibility to Go 1.7, which might be removed.
-
-It is possible that a later version will match the `math/bits` return signature for counts (which is `int`, rather than our library's `unit64`). If so, the version will be bumped.
-
-## Installation
