| Welcome to the spoken tutorial on''' Working with Remote Repositories'''.

|-
| 00:06
| In this tutorial, we will learn -  What is '''Remote repository''' and 

|-
| 00:12
| How to synchronize data to the '''Remote repository'''

|-
|00:16
| For this tutorial, I am using  '''Ubuntu Linux 14.04'''

|-
| 00:22
|  '''Git 2.3.2''' 

|-
| 00:25
|  '''gedit Text Editor''' and

|-
| 00:28
|  '''Firefox web browser'''

|-
| 00:30
| You can use any editor and web browser of your choice.

|-
| 00:36
| For this tutorial, you will need a working''' Internet''' connection.

|-
| 00:41
|You should also have knowledge of basics of''' Git''' commands.

|-
| 00:46
| If not, for relevant''' Git''' tutorials, please visit the link shown.

|-
| 00:52
| First let us understand what is a '''Remote repository'''.

|-
| 00:56
| A '''repository''' which is hosted on the internet or any network is called''' Remote repository.'''

|-
| 01:04
| Using this centralized '''repository''', people can collaborate on a project from anywhere in the world, at anytime.

|-
| 01:13
| Say, for example, there are 3 users who want to work jointly in the same '''repository'''.

|-
| 01:21
|'''Git''' allows them to take a copy of the '''Remote repository''' into their local system.

|-
| 01:28
|This will be done using''' clone''' command.

|-
| 01:31
|Then they can work offline with the local '''repository'''.

|-
| 01:36
|Once the work is satisfied, they have to synchronize it back to the main '''repository'''.

|-
| 01:43
|This will be done using''' Push''' and''' pull''' commands.

|-
| 01:48
|You will understand the full process at the end of this tutorial.

|-
| 01:53
| First we will open our '''GitHub repository''' which we created earlier.

|-
| 01:59
| In the right side, we can see the '''URL''' of this '''repository'''.

|-
| 02:05
| Let’s copy this '''URL'''.

|-
| 02:08
|We are going to make a copy of this '''repository''' using the '''URL''' to create a local '''repository'''.

|-
| 02:16
| Let’s open the '''terminal'''.

|-
| 02:18
|Let us understand now how two users can work in the same '''Remote repository.'''

|-
| 02:24
|For this, I have already created two directories named''' User1''' and''' User2''' on my '''Desktop'''.

|-
| 02:33
|Please do so on your '''Desktop''' also.

|-
| 02:36
| In the same '''terminal''', I will open the directories in 2 different tabs.

|-
| 02:43
|In the first tab, type''' cd space User1''' 

|-
| 02:49
|To open second tab, click on''' File menu''' and select''' Open Tab'''.

|-
| 02:55
|In the second tab, type''' cd User2'''

|-
| 03:00
| Let us go to the tab''' User1'''.

|-
| 03:03
| Now let us make a copy of the '''Remote repository'''.

|-
| 03:08
|Type''' git space clone''' and then paste the copied '''URL ''' space  and type a dot at the end of this command.

|-
| 03:17
| '''Dot''' indicates that we are going to copy the '''repository''' inside the same '''directory '''i.e.''' User1'''.

|-
| 03:25
|Otherwise, it will create a new '''directory '''with the '''repository''' name as''' stories'''.

|-
| 03:31
| Now press''' Enter'''.

|-
| 03:33
| The''' clone''' command will copy the whole central folder and make it as a local''' repository.'''

|-
|03:40
| Type '''ls.''' You can see that the content of the '''Remote repository''' is copied here.

|-
| 03:48
| Next, I will change the '''user name '''and '''email id''' of this '''repository''' for better understanding.

|-
| 03:55
|I have already created two more '''GitHub users '''-''' priya-spoken1''' and''' kaushik-spoken''' - for demonstration purpose.

|-
| 04:04
|I will use them here.

|-
| 04:14
| Let us check the''' Git log'''.

|-
| 04:16
|You can see the same '''commits''' of the '''Remote repository'''.

|-
| 04:21
| Likewise, I will '''clone''' the '''repository''' inside the '''directory User2''' in the second tab.

|-
| 04:28
| Here also I will change the '''user name '''and '''email id''' as I did earlier for''' User1'''.

|-
| 04:35
| Next, let us understand how these users will work in the '''Remote repository'''.

|-
| 04:41
| Let’s say,''' User1''' will be working on a file named''' lion-and-mouse.html'''.

|-
| 04:48
| To create the file, type''' gedit lion-and-mouse.html.'''

|-
| 04:54
| I will copy and paste some text into this file, from my''' Writer document,''' which I had saved earlier.

|-
| 05:02
|Likewise, you can add some content into your file.

|-
| 05:06
| Let's add the file into the''' staging area'''.

|-
| 05:11
|Type''' git add lion-and-mouse.html'''

|-
| 05:17
| Next let us '''commit''' the newly added file.

|-
| 05:21
|Type''' git commit hyphen m''' within quotes''' Added lion-and-mouse.html'''.

|-
| 05:29
| Next we have to synchronize the local '''repository''' with the main '''Remote repository'''.

|-
| 05:35
|Before synchronizing the '''repository''', we will learn about '''remotes'''.

|-
| 05:40
|  The '''URL''' of a '''Remote repository''' is called''' Remote'''.

|-
| 05:45
| We can give a nickname to the '''URL'''.

|-
| 05:49
| It will be useful when we work on many '''Remote repositories.'''

|-
| 05:54
| When we synchronize the '''repository''', we can simply use the nickname, instead of typing the full '''URL'''.

|-
| 06:01
| The default nickname of a '''Remote''' is always''' origin'''.

|-
| 06:06
| Now let us learn how to add a '''Remote'''.

|-
| 06:10
| Switch back to our '''terminal'''.

|-
| 06:13
|Type''' git remote'''. You can see that the default '''Remote''' name is''' origin'''.

|-
| 06:20
| Next let us see how to add a nickname to the '''Remote'''.

|-
| 06:25
|Type''' git remote add stories''' and type the '''URL''' of the '''Remote''' '''repository.'''

|-
| 06:32
|Here I will name the '''Remote''' as''' stories''' that is the '''Remote''' '''repository''' name.

|-
| 06:38
|Now press '''Enter''' key.

|-
| 06:41
| Again to check the '''Remote''' list, type''' git remote'''.

|-
| 06:46
|You can see that the '''Remote''' is added to the list.

|-
| 06:50
| Now we will synchronize the local '''repository''' with the main '''Remote''' '''repository'''.

|-
| 06:55
|To do so, type''' git push stories master'''

|-
| 07:00
| Here''' stories''' is the '''Remote''' name and''' master''' is the '''branch''' where we update the changes.

|-
| 07:07
| Now press''' Enter'''.

|-
| 07:09
| I will type''' priya-spoken1''' as '''username''' of''' User1''' and press''' Enter'''.

|-
| 07:17
| Type the corresponding password of''' User1'''.

|-
| 07:21
| Recall that I created this username earlier for demonstration purpose.

|-
| 07:27
|Please use your username and password here.

|-
| 07:31
| It throws an error''' unable to access'''.

|-
| 07:35
| Why did this error occur? This is because we don't have access to the '''Remote repository.'''

|-
| 07:42
| So now, let us learn how to give access permission to the contributors.

|-
|07:48
| Switch back to '''GitHub repository.'''

|-
|07:51
| Click on the last tab -''' Settings''' - in the top panel.

|-
|07:55
| Then click on''' Collaborators''' link in the left side box.

|-
| 08:00
|Type your '''GitHub''' account password for confirmation.

|-
|08:04
| Here in the text box, we can add the names of the collaborators.

|-
| 08:10
|Understand that anyone can '''clone''' this '''GitHub repository.'''

|-
| 08:15
|But the people who we add as collaborator, can '''push''' to the '''repository'''.

|-
| 08:21
| Now I will add the two users''' priya-spoken1''' and''' kaushik-spoken'''.

|-
| 08:27
|You can see that the user name is listed when I type in the text box.

|-
| 08:33
| Click on''' Add Collaborator '''button to add the user as collaborator.

|-
| 08:38
| I will also add the other user''' kaushik-spoken'''.

|-
| 08:43
| You can see here the added names are listed.

|-
| 08:47
| Now we will try to push into the '''Remote repository'''.

|-
| 08:51
| Switch back to  '''terminal'''.

|-
| 08:54
| Type''' git push stories master'''

|-
| 08:58
| Give the '''username''' and '''password''' of the user who has the access to the '''repository'''.

|-
| 09:04
| You can see that we have pushed it successfully.

|-
| 09:08
| Next, let us check the '''GitHub repository''' to see whether our changes are updated.

|-
| 09:14
| Switch back to the '''GitHub repository.'''

|-
| 09:17
| Click on the '''Code''' tab.

|-
| 09:20
| Let’s check the '''commit list.'''

|-
| 09:23
| You can see that the '''commit''' of the collaborator is listed here.

|-
| 09:28
| Next, let us learn how''' User2''' can collaborate with the '''Remote repository.'''

|-
| 09:34
| Switch back to the '''terminal'''.

|-
| 09:37
| Let’s say,''' User2''' is working on a file named''' friends.html'''.

|-
| 09:43
| To create the file, type''' gedit friends.html.'''

|-
| 09:49
| I will copy and paste some text into this file, from my''' Writer document'''.

|-
| 09:54
|Likewise, you can add some content into your file.

|-
|09:59
| Let's add the file into the '''staging area.'''

|-
| 10:03
| Next let’s '''commit''' the newly added file.

|-
| 10:07
|Type''' git commit hyphen m''' within quotes''' Added friends.html'''.

|-
| 10:15
| Next we have to synchronize the local '''repository''' with the main '''Remote repository.'''

|-
| 10:21
|Type''' git push origin master'''

|-
| 10:25
| Remember that we didn't add '''Remote''' to this local '''repository'''. 

|-
| 10:30
|So here we are using the default '''Remote''' name''' origin'''.

|-
| 10:34
| Now press''' Enter'''.

|-
| 10:37
|Type the '''GitHub''' username and password of the '''User2'''.

|-
| 10:42
| It throws an error which says''' failed to push.'''

|-
| 10:46
| Also, it shows the reason for the error:''' the remote contains work that you do not have locally.'''

|-
| 10:53
|Remember that the''' User1''' has pushed a commit earlier. 

|-
| 10:58
|But''' User2''' doesn't have the work of''' User1''' in its local '''repository'''.

|-
| 11:04
| It also gives a suggestion to run''' git pull''' command to rectify the error.

|-
| 11:10
| So first, we have to pull down the work of''' User1''' and incorporate it into the''' User2'''’s local '''repository'''. Let’s do it now.

|-
| 11:21
| Type''' git pull origin master'''

|-
| 11:25
| First it will fetch the data from '''Remote''' '''repository''' then '''merge''' it with the local '''repository'''.

|-
| 11:32
|So it opens an editor to give a message for '''merging'''.

|-
| 11:36
|Let’s keep the same message and close the editor by pressing''' Ctrl + X'''.

|-
| 11:42
| Now again, we will try to push the data. Type''' git push origin master'''

|-
| 11:50
| Give the '''username''' and '''password''' of''' User2'''.

|-
| 11:54
| You can see that we could successfully push the data now.

|-
| 11:59
| Next let us check the '''GitHub repository''' to see whether our changes are updated.

|-
| 12:05
|Switch back to the '''GitHub repository.'''

|-
| 12:08
| Click on the repository name '''Stories'''.

|-
| 12:12
| You can see that the file''' friends.html''' is now added to the '''repository'''.

|-
| 12:18
| Let’s check the '''commit list '''now.

|-
| 12:21
|You can see that the '''commit''' of '''User2''' is also listed here.

|-
| 12:26
| With this, we come to the end of this tutorial.

|-
| 12:30
| Let us summarize. In this tutorial, we have learnt -

|-
| 12:35
| What is '''Remote repository '''and

|-
| 12:38
| How to synchronize data to the '''Remote repository'''

|-
| 12:42
| As an assignment,  Create one more user named '''User3'''

|-
| 12:47
| '''Clone''' data for '''User3'''

|-
| 12:50
| Start working on the local''' repository '''of''' User3''' and

|-
| 12:54
| Try to push data from '''User3'''
