+[Generators](https://en.wikipedia.org/wiki/Generator_(computer_programming)) yields a sequence of values one at a time.
 
-# Implementation and Example
+## Implementation 
 
-You can find the implementation and usage in [generator.go](generator.go)
+```go
+func Count(start int, end int) chan int {
+    ch := make(chan int)
+
+    go func(ch chan int) {
+        for i := start; i < end ; i++ {
+            // Blocks on the operation
+            ch <- result
+        }
+
+		close(ch)
+	}(ch)
+
+	return ch
+}
+```
+
+## Usage
+
+```go
+fmt.Println("No bottles of beer on the wall")
+
+for i := range Count(1, 99) {
+    fmt.Println("Pass it around, put one up,", i, "bottles of beer on the wall")
+    // Pass it around, put one up, 1 bottles of beer on the wall
+    // Pass it around, put one up, 2 bottles of beer on the wall
+    // ...
+    // Pass it around, put one up, 99 bottles of beer on the wall
+}
+
+fmt.Println(100, "bottles of beer on the wall")
+```
