-# Terminal progress bar for Go  
-
-Simple progress bar for console programs.    
-   
-Please check the new version https://github.com/cheggaaa/pb/tree/v2 (currently, it's beta)
-
-## Installation
-
-```
-go get gopkg.in/cheggaaa/pb.v1
-```   
-
-## Usage   
-
-```Go
-package main
-
-import (
-	"gopkg.in/cheggaaa/pb.v1"
-	"time"
-)
-
-func main() {
-	count := 100000
-	bar := pb.StartNew(count)
-	for i := 0; i < count; i++ {
-		bar.Increment()
-		time.Sleep(time.Millisecond)
-	}
-	bar.FinishPrint("The End!")
-}
-
-```
-
-Result will be like this:
-
-```
-> go run test.go
-37158 / 100000 [================>_______________________________] 37.16% 1m11s
-```
-
-## Customization
-
-```Go  
-// create bar
-bar := pb.New(count)
-
-// refresh info every second (default 200ms)
-bar.SetRefreshRate(time.Second)
-
-// show percents (by default already true)
-bar.ShowPercent = true
-
-// show bar (by default already true)
-bar.ShowBar = true
-
-// no counters
-bar.ShowCounters = false
-
-// show "time left"
-bar.ShowTimeLeft = true
-
-// show average speed
-bar.ShowSpeed = true
-
-// sets the width of the progress bar
-bar.SetWidth(80)
-
-// sets the width of the progress bar, but if terminal size smaller will be ignored
-bar.SetMaxWidth(80)
-
-// convert output to readable format (like KB, MB)
-bar.SetUnits(pb.U_BYTES)
-
-// and start
-bar.Start()
-``` 
-
-## Progress bar for IO Operations
-
-```go
-// create and start bar
-bar := pb.New(myDataLen).SetUnits(pb.U_BYTES)
-bar.Start()
-
-// my io.Reader
-r := myReader
-
-// my io.Writer
-w := myWriter
-
-// create proxy reader
-reader := bar.NewProxyReader(r)
-
-// and copy from pb reader
-io.Copy(w, reader)
-
-```
-
-```go
-// create and start bar
-bar := pb.New(myDataLen).SetUnits(pb.U_BYTES)
-bar.Start()
-
-// my io.Reader
-r := myReader
-
-// my io.Writer
-w := myWriter
-
-// create multi writer
-writer := io.MultiWriter(w, bar)
-
-// and copy
-io.Copy(writer, r)
-
-bar.Finish()
-```
-
-## Custom Progress Bar Look-and-feel
-
-```go
-bar.Format("<.- >")
-```
-
-## Multiple Progress Bars (experimental and unstable)
-
-Do not print to terminal while pool is active.
-
-```go
-package main
-
-import (
-    "math/rand"
-    "sync"
-    "time"
-
-    "gopkg.in/cheggaaa/pb.v1"
-)
-
-func main() {
-    // create bars
-    first := pb.New(200).Prefix("First ")
-    second := pb.New(200).Prefix("Second ")
-    third := pb.New(200).Prefix("Third ")
-    // start pool
-    pool, err := pb.StartPool(first, second, third)
-    if err != nil {
-        panic(err)
-    }
-    // update bars
-    wg := new(sync.WaitGroup)
-    for _, bar := range []*pb.ProgressBar{first, second, third} {
-        wg.Add(1)
-        go func(cb *pb.ProgressBar) {
-            for n := 0; n < 200; n++ {
-                cb.Increment()
-                time.Sleep(time.Millisecond * time.Duration(rand.Intn(100)))
-            }
-            cb.Finish()
-            wg.Done()
-        }(bar)
-    }
-    wg.Wait()
-    // close pool
-    pool.Stop()
-}
-```
-
-The result will be as follows:
-
-```
-$ go run example/multiple.go 
-First  34 / 200 [=========>---------------------------------------------]  17.00% 00m08s
-Second  42 / 200 [===========>------------------------------------------]  21.00% 00m06s
-Third  36 / 200 [=========>---------------------------------------------]  18.00% 00m08s
