1 00:00:01,230 --> 00:00:02,900 ‫So, the Heroku platform, 2 00:00:02,900 --> 00:00:04,940 ‫where we're gonna deploy our project, 3 00:00:04,940 --> 00:00:07,210 ‫works very closely with Git, 4 00:00:07,210 --> 00:00:09,690 ‫and so, in this lecture, we're gonna install 5 00:00:09,690 --> 00:00:11,960 ‫and set up Git on your computer 6 00:00:11,960 --> 00:00:15,730 ‫and also open an account at github.com. 7 00:00:15,730 --> 00:00:19,270 ‫Now if you're already familiar with Git and GitHub, 8 00:00:19,270 --> 00:00:21,780 ‫then please feel free to mark this video 9 00:00:21,780 --> 00:00:23,890 ‫and the next ones as completed, 10 00:00:23,890 --> 00:00:25,530 ‫and move on to the ones 11 00:00:25,530 --> 00:00:28,603 ‫where we actually deploy the project to Heroku. 12 00:00:30,180 --> 00:00:34,570 ‫So, in order to install Git, let's search for Git, 13 00:00:34,570 --> 00:00:36,990 ‫and then the first result that shows up, 14 00:00:36,990 --> 00:00:41,890 ‫which is git-scm should be the one that you're looking for. 15 00:00:41,890 --> 00:00:44,300 ‫Now, what actually is Git? 16 00:00:44,300 --> 00:00:47,710 ‫Well, Git is a version control software, 17 00:00:47,710 --> 00:00:50,530 ‫so a software that runs on your computer 18 00:00:50,530 --> 00:00:53,400 ‫and which basically allows you to save snapshots 19 00:00:53,400 --> 00:00:55,130 ‫of your code over time, 20 00:00:55,130 --> 00:00:59,240 ‫so that you can go back in time in your code if you need to. 21 00:00:59,240 --> 00:01:01,210 ‫And that is really only the surface. 22 00:01:01,210 --> 00:01:05,006 ‫So Git really is an incredibly complex and huge topic 23 00:01:05,006 --> 00:01:08,300 ‫and which could be a whole course on its own. 24 00:01:08,300 --> 00:01:10,180 ‫So, in this lecture and the next ones, 25 00:01:10,180 --> 00:01:14,170 ‫I will really just give you the very, very basics of Git. 26 00:01:14,170 --> 00:01:15,340 ‫All right. 27 00:01:15,340 --> 00:01:18,090 ‫So again, what you really need to know about Git 28 00:01:18,090 --> 00:01:20,530 ‫is that it's a version control software 29 00:01:20,530 --> 00:01:22,930 ‫which allows you to save your code over time 30 00:01:22,930 --> 00:01:25,580 ‫in different commits and branches. 31 00:01:25,580 --> 00:01:28,400 ‫And all of this happens inside a repository. 32 00:01:28,400 --> 00:01:29,940 ‫So, for each of your projects, 33 00:01:29,940 --> 00:01:32,560 ‫you will create a repository, and then, in there, 34 00:01:32,560 --> 00:01:35,130 ‫you will create commits and different branches, 35 00:01:35,130 --> 00:01:38,400 ‫and you will learn all of that in the next video. 36 00:01:38,400 --> 00:01:39,540 ‫All right. 37 00:01:39,540 --> 00:01:42,970 ‫Anyway, for now, let's actually go ahead and download Git. 38 00:01:42,970 --> 00:01:45,430 ‫And I will not do it now because, of course, 39 00:01:45,430 --> 00:01:47,053 ‫I already have Git installed. 40 00:01:47,910 --> 00:01:49,790 ‫So once you're done installing it, 41 00:01:49,790 --> 00:01:51,253 ‫let's open up the Terminal. 42 00:01:52,310 --> 00:01:55,650 ‫And to check if it's actually installed on your computer, 43 00:01:55,650 --> 00:01:59,290 ‫type git dash dash version. 44 00:01:59,290 --> 00:02:01,270 ‫And then, if you get any output, 45 00:02:01,270 --> 00:02:05,180 ‫well, then it means that your installation was successful. 46 00:02:05,180 --> 00:02:06,970 ‫Now, there are a bunch of different 47 00:02:06,970 --> 00:02:08,590 ‫graphical user interfaces 48 00:02:08,590 --> 00:02:11,470 ‫in order to interact with Git on your computer, 49 00:02:11,470 --> 00:02:13,520 ‫but I will show you everything you need to know 50 00:02:13,520 --> 00:02:16,780 ‫in order to get started with Git using the command line, 51 00:02:16,780 --> 00:02:19,700 ‫because I believe that it's actually a way better way 52 00:02:19,700 --> 00:02:21,810 ‫of learning to work with Git. 53 00:02:21,810 --> 00:02:24,820 ‫And also, once you're comfortable with most of the commands, 54 00:02:24,820 --> 00:02:26,910 ‫it's actually much faster and easier 55 00:02:26,910 --> 00:02:28,470 ‫to just use the command line 56 00:02:28,470 --> 00:02:31,930 ‫instead of messing with a graphical user interface. 57 00:02:31,930 --> 00:02:33,070 ‫All right. 58 00:02:33,070 --> 00:02:34,610 ‫Anyway, let's now go ahead 59 00:02:34,610 --> 00:02:37,363 ‫and create an account on github.com. 60 00:02:39,550 --> 00:02:43,760 ‫So that's GitHub, and so github.com 61 00:02:43,760 --> 00:02:48,650 ‫is where we want to now sign up for a new account. 62 00:02:48,650 --> 00:02:51,070 ‫And GitHub is basically a platform 63 00:02:51,070 --> 00:02:54,490 ‫where you can host your own Git repositories for free, 64 00:02:54,490 --> 00:02:56,780 ‫in order to share it with other developers 65 00:02:56,780 --> 00:02:59,500 ‫or just to keep it secure for yourself. 66 00:02:59,500 --> 00:03:01,640 ‫So, every single developer that I know 67 00:03:01,640 --> 00:03:04,030 ‫actually uses Git and GitHub, 68 00:03:04,030 --> 00:03:07,430 ‫and so, if you haven't used it up until this point, 69 00:03:07,430 --> 00:03:10,800 ‫then it's really a great time to join all the developers 70 00:03:10,800 --> 00:03:14,770 ‫that really rely on the service every single day. 71 00:03:14,770 --> 00:03:17,670 ‫So, of course, I'm not gonna create a new account here, 72 00:03:17,670 --> 00:03:19,340 ‫because I already have one, 73 00:03:19,340 --> 00:03:21,950 ‫but please go ahead and do that now. 74 00:03:21,950 --> 00:03:24,983 ‫And then, once you're ready, let's go back to the Terminal. 75 00:03:28,330 --> 00:03:30,710 ‫So, what I want to do now is to, very quickly, 76 00:03:30,710 --> 00:03:33,340 ‫configure your local Git installation 77 00:03:33,340 --> 00:03:35,400 ‫with the name and email address 78 00:03:35,400 --> 00:03:37,230 ‫that you just used on GitHub. 79 00:03:37,230 --> 00:03:42,230 ‫So that's git config, then dash dash global, 80 00:03:44,260 --> 00:03:47,823 ‫then user.name, and then your name. 81 00:03:49,310 --> 00:03:52,063 ‫So let's say that's Jonas Schmedtmann, 82 00:03:53,800 --> 00:03:58,097 ‫and then hit Enter, and that's it, all right? 83 00:03:58,097 --> 00:04:01,420 ‫So that's the name, and then also the email. 84 00:04:01,420 --> 00:04:06,170 ‫So that's git config, global, again, 85 00:04:06,170 --> 00:04:11,170 ‫user.email, and then your email here, also in quotes. 86 00:04:12,050 --> 00:04:12,883 ‫All right. 87 00:04:13,720 --> 00:04:16,400 ‫So, that's it for this video actually. 88 00:04:16,400 --> 00:04:18,330 ‫In the next one, we're then gonna learn 89 00:04:18,330 --> 00:04:20,950 ‫the real basics of Git. 90 00:04:20,950 --> 00:04:24,520 ‫All right, so after this video and the next two one, 91 00:04:24,520 --> 00:04:26,480 ‫I hope that you will really be able 92 00:04:26,480 --> 00:04:29,010 ‫to start using Git in your own projects, 93 00:04:29,010 --> 00:04:31,020 ‫which I believe is really important for you 94 00:04:31,020 --> 00:04:32,673 ‫as a professional developer.
