+## Usage
+
+### Use the binary directly
+It's really simple to use, just get the video id from youtube url - ex: `https://www.youtube.com/watch?v=rFejpH_tAHM`, the video id is `rFejpH_tAHM`
+
+```shell
+$ youtubedr download QAGDGja7kbs
+$ youtubedr download https://www.youtube.com/watch?v=rFejpH_tAHM
+```
+
+
+### Use this package in your golang program
+
+Please check out the [example_test.go](example_test.go) for example code.
+
+
+## Example:
+ * ### Get information of dotGo-2015-rob-pike video for downloading
+
+    `go get github.com/kkdai/youtube/v2/youtubedr`
+
+    Download video from [dotGo 2015 - Rob Pike - Simplicity is Complicated](https://www.youtube.com/watch?v=rFejpH_tAHM)
+
+    ```

+    ```
+ * ### Download dotGo-2015-rob-pike-video
+
+    `go get github.com/kkdai/youtube/v2/youtubedr`
+
+    Download video from [dotGo 2015 - Rob Pike - Simplicity is Complicated](https://www.youtube.com/watch?v=rFejpH_tAHM)
+
+    ```
+    youtubedr download https://www.youtube.com/watch?v=rFejpH_tAHM
+    ```
+
+ * ### Download video to specific folder and name
+
+	`go get github.com/kkdai/youtube/v2/youtubedr`
+
+	Download video from [dotGo 2015 - Rob Pike - Simplicity is Complicated](https://www.youtube.com/watch?v=rFejpH_tAHM) to current directory and name the file to simplicity-is-complicated.mp4
+
+	```
+	youtubedr download -d ./ -o simplicity-is-complicated.mp4 https://www.youtube.com/watch?v=rFejpH_tAHM
+	```
+
+ * ### Download video with specific quality
+
+	`go get github.com/kkdai/youtube/v2/youtubedr`
+
+	Download video from [dotGo 2015 - Rob Pike - Simplicity is Complicated](https://www.youtube.com/watch?v=rFejpH_tAHM) with specific quality
+
+	```
+	youtubedr download -q medium https://www.youtube.com/watch?v=rFejpH_tAHM
+	```
+
+   #### Special case by quality hd1080:
+   Installation of ffmpeg is necessary for hd1080
+   ```
+   ffmpeg   //check ffmpeg is installed, if not please download ffmpeg and set to your PATH.
+   youtubedr download -q hd1080 https://www.youtube.com/watch?v=rFejpH_tAHM
+   ```
+
+
+ * ### Download video with specific itag
+
+    `go get github.com/kkdai/youtube/v2/youtubedr`
+
+    Download video from [dotGo 2015 - Rob Pike - Simplicity is Complicated](https://www.youtube.com/watch?v=rFejpH_tAHM)
+
+    ```
+    youtubedr download -q 18 https://www.youtube.com/watch?v=rFejpH_tAHM
+    ```
+
+## How it works
+
+- Parse the video ID you input in URL
+	- ex: `https://www.youtube.com/watch?v=rFejpH_tAHM`, the video id is `rFejpH_tAHM`
+- Get video information via video id.
+	- Use URL: `http://youtube.com/get_video_info?video_id=`
+- Parse and decode video information.
+	- Download URL in "url="
+	- title in "title="
+- Download video from URL
+	- Need the string combination of "url"
