+# Multi Progress Bar
+
+[![GoDoc](https://pkg.go.dev/badge/github.com/vbauerster/mpb)](https://pkg.go.dev/github.com/vbauerster/mpb/v7)
+[![Build Status](https://travis-ci.org/vbauerster/mpb.svg?branch=master)](https://travis-ci.org/vbauerster/mpb)

+
+**mpb** is a Go lib for rendering progress bars in terminal applications.
+
+## Features
+
+- **Multiple Bars**: Multiple progress bars are supported
+- **Dynamic Total**: Set total while bar is running
+- **Dynamic Add/Remove**: Dynamically add or remove bars
+- **Cancellation**: Cancel whole rendering process
+- **Predefined Decorators**: Elapsed time, [ewma](https://github.com/VividCortex/ewma) based ETA, Percentage, Bytes counter
+- **Decorator's width sync**: Synchronized decorator's width among multiple bars
+
+## Usage
+
+#### [Rendering single bar](_examples/singleBar/main.go)
+
+```go
+package main
+
+import (
+    "math/rand"
+    "time"
+
+    "github.com/vbauerster/mpb/v7"
+    "github.com/vbauerster/mpb/v7/decor"
+)
+
+func main() {
+    // initialize progress container, with custom width
+    p := mpb.New(mpb.WithWidth(64))
+
+    total := 100
+    name := "Single Bar:"
+    // adding a single bar, which will inherit container's width
+    bar := p.Add(int64(total),
+        // progress bar filler with customized style
+        mpb.NewBarFiller(mpb.BarStyle().Lbound("╢").Filler("▌").Tip("▌").Padding("░").Rbound("╟")),
+        mpb.PrependDecorators(
+            // display our name with one space on the right
+            decor.Name(name, decor.WC{W: len(name) + 1, C: decor.DidentRight}),
+            // replace ETA decorator with "done" message, OnComplete event
+            decor.OnComplete(
+                decor.AverageETA(decor.ET_STYLE_GO, decor.WC{W: 4}), "done",
+            ),
+        ),
+        mpb.AppendDecorators(decor.Percentage()),
+    )
+    // simulating some work
+    max := 100 * time.Millisecond
+    for i := 0; i < total; i++ {
+        time.Sleep(time.Duration(rand.Intn(10)+1) * max / 10)
+        bar.Increment()
+    }
+    // wait for our bar to complete and flush
+    p.Wait()
+}
+```
+
+#### [Rendering multiple bars](_examples/multiBars/main.go)
+
+```go
+    var wg sync.WaitGroup
+    // passed &wg will be accounted at p.Wait() call

+                // simple name decorator
+                decor.Name(name),
+                // decor.DSyncWidth bit enables column width synchronization
+                decor.Percentage(decor.WCSyncSpace),
+            ),
+            mpb.AppendDecorators(
+                // replace ETA decorator with "done" message, OnComplete event
+                decor.OnComplete(

+                ),
+            ),
+        )
+        // simulating some work
+        go func() {
+            defer wg.Done()
+            rng := rand.New(rand.NewSource(time.Now().UnixNano()))
+            max := 100 * time.Millisecond
+            for i := 0; i < total; i++ {
+                // start variable is solely for EWMA calculation
+                // EWMA's unit of measure is an iteration's duration
+                start := time.Now()
+                time.Sleep(time.Duration(rng.Intn(10)+1) * max / 10)
+                bar.Increment()
+                // we need to call DecoratorEwmaUpdate to fulfill ewma decorator's contract
+                bar.DecoratorEwmaUpdate(time.Since(start))

+        }()
