Slide 1:	Welcome to the spoken tutorial on Tagging in Git.
lide 2:	In this tutorial, we will learn about Tagging and Types of tagging
Slide 3:	For this tutorial, I am using Ubuntu Linux 14.04 Git 2.3.2 and gedit Text Editor You can use any editor of your choice.
Slide 4:	To follow this tutorial You must have knowledge of running Linux commands on Terminal. If not, for relevant Linux tutorials, please visit our website.
	Let us learn about tagging.
Slide 5	* Tagging is used to mark a commit stage as important. We can tag a commit, like a bookmark, for future references. Typically, this is used to mark release point of a project such as v1.0.
Slide 6	There are two types of tags: Lightweight tag and Annotated tag
	First I will demonstrate how to create a lightweight tag.
Press Ctrl+Alt+T to open the terminal	Let us go to our Git repository mywebpage which we created earlier.
Type cd mywebpage and press Enter	Switch to the terminal and type: cd space mywebpage and press Enter.
	I will continue to use html files for demonstration. You may use any file type of your choice.
Type git log --oneline	Let’s check the Git log by typing git space log space hyphen hyphen oneline and press Enter.
Highlight the commits	Currently, we have three commits in our repository namely "Added colors, Added history and Initial commit".
Highlight “Added colors”	Now I will create a lightweight tag in the latest commit “Added colors”. When we create a tag, by default, it will be created in the latest commit.
Type git tag v1.1 and press Enter	Type git space tag space v1.1 and press Enter.
Highlight v1.1	Here I will give v1.1 as the tag name. You can give any name of your choice.
Type git tag and press Enter	You can see the tag by typing git space tag and press Enter. Now we have only one tag in our repository. <<PAUSE>>
	Next we will learn how to create an annotated tag.
	First I will make some modifications in the file mypage.html for demonstration purpose.
Type gedit mypage.html ampersand and press Enter Add lines in the file	Type gedit space mypage.html space ampersand and press Enter. Let us add some lines in the file.
Save and close the file	Then save and close the file.
	Let’s commit our work at this point.
Type git commit -am “Added content in mypage.html” and press Enter	Type git space commit space hyphen a m space within double quotes “Added content in mypage.html” and press Enter.
	Let us assume that this particular stage is very important to the project. So we have to create a tag at this commit point.
Type git tag -a v1.2 -m “My Version 1.2” and press Enter Highlight -m “Version 1.2”	Here we will create an annotated tag. Type git space tag space hyphen a space v1.2 space hyphen m space within doubt quotes “My Version 1.2” and press Enter. Using -m flag, you can give any tag message of your choice. Here the tag message is optional.
Type git tag and press Enter	To see the tag list, type git space tag and press Enter. Now we have two tags.
Highlight v1.1 Highlight v1.2	Here v1.1 is the lightweight tag and v1.2 is the annotated tag. How do we differentiate between the tags?
	We can see the difference between the two tags by using git show command.
Type git show v1.1 and press Enter	Type git space show space v1.1 and press Enter.
Highlight commit details and file changes	Here we can see the complete details of the lightweight tag v1.1. It simply shows the commit details and file changes.
Type git show v1.2 and press Enter	Next, we will see the details of the annotated tag v1.2. Type git space show space v1.2 and press Enter.
Highlight tag v1.2 Highlight Tagger and Date Highlight date and time Highlight Version 1.2 Highlight commit details Highlight file changes	Here we can see the tag name tagger details date the commit was tagged tag message commit details and file changes.
	Annotated tag is always recommended when you work collaboratively. <<PAUSE>>
	Let us now learn how to mark a tag in our old commits.
Type git log --oneline and press Enter	First, we will check the Git log by typing git space log space hyphen hyphen oneline and press Enter.
Type git tag -a v1.0 hash -m “My Version 1.0” and press Enter	Now for instance, I want to create a tag in my second commit “Added history.html” Type git space tag space hyphen a space v1.0 space. Then copy and paste the commit hash of the “Added history.html” space. Type hyphen m space within double quotes “My Version 1.0” and press Enter.
Type git tag and press Enter	We will be able to see the tag which we created now, by typing git space tag and press Enter.
Highlight v1.0	You can see the tag v1.0 is created here.
	Next we will learn how to see the tags along with the Git log.
Type git log --oneline --decorate and press Enter	Type git space log space hyphen hyphen oneline space hyphen hyphen decorate and press Enter.
	You can see the Git log along with the tag names. <<PAUSE>>
	Now, we will learn to delete an unwanted tag.
Highlight v1.1 Type git tag -d v1.1 and press Enter Highlight “Deleted tag 'v1.1'” Highlight hash	Say, I want to delete the tag v1.1. Type git space tag space hyphen d space v1.1 and press Enter. It shows the message “Deleted tag 'v1.1'” and its commit hash.
Type git tag and press Enter	We will check whether the tag is deleted or not. Type git space tag and press Enter. Now, we can't see the tag v1.1 as it has been deleted successfully. <<PAUSE>>
	With this, we come to the end of this tutorial.
