Projects on GitHub.com can be accessed and managed using the standard [[Git]] command-line interface; all standard Git commands work with it. GitHub.com also allows users to browse public [[Content repository|repositories]] on the site. Multiple desktop clients and Git [[Plug-in (computing)|plugins]] are also available. TheIn addition, the site provides [[social networking]]-like functions such as feeds, followers, wikis (using [[wiki software]] called [[Gollum Wiki|Gollum]]), and a [[Collaboration graph|social network graph]] to display how developers work on their versions ("[[fork (software development)|forks]]") of a repository and what fork (and branch within that fork) is newest.
 
Anyone can browse and download public repositories, but only registered users can contribute content to repositories. With a registered user account, users are able tocan have discussions, manage repositories, submit contributions to others' repositories, and [[code review|review changes to code]].

=== Scope ===
The primary purpose of GitHub is to facilitate the [[version control]] and [[Issue tracking system|issue tracking]] aspects of software development. Labels, milestones, responsibility assignment, and a search engine are available for issue tracking. For version control, Git (and, by extension, GitHub) allows [[pull request]]s to propose changes to the source code. Users who can review the proposed changes can see a diff between the requested changes and approve them. In Git terminology, this action is called "committing" and one instance of it is a "commit." A history of all commits is kept and can be viewed at a later time.

=== GitHub Actions ===
As with the rest of GitHub, it includes both free and paid tiers of service, instead of being supported by [[Online advertising|web advertising]]. Web sites generated through this service are hosted either as [[subdomain]]s of the github.io ___domain, or as custom [[Domain name|domains]] bought through a third-party [[___domain name registrar]].<ref>{{Cite book|url=https://books.google.com/books?id=WwJwDQAAQBAJ&pg=PA340|title=Ubuntu Server Cookbook|last=Sawant|first=Uday R.|date=2016-06-30|publisher=Packt Publishing Ltd|isbn=9781785887987|language=en|access-date=June 15, 2019|archive-date=August 1, 2020|archive-url=https://web.archive.org/web/20200801224628/https://books.google.com/books?id=WwJwDQAAQBAJ&pg=PA340|url-status=live}}</ref> When custom ___domain is set on a GitHub Pages repo a [[Let's Encrypt]] certificate for it is generated automatically.

GitHub Actions was officially launched on November 13, 2019. It was first announced in October 2018 at GitHub Universe as a way to automate workflows, but the full general availability (GA) release came a year later in 2019. GitHub Actions,<ref>{{Cite web|title=What is GitHub Actions? • GitHub Actions|url=https://resources.github.com/downloads/What-is-GitHub.Actions_.Benefits-and-examples.pdf|access-date=2021-12-06|website=GitHub|language=en|archive-date=December 3, 2021|archive-url=https://web.archive.org/web/20211203130324/https://resources.github.com/downloads/What-is-GitHub.Actions_.Benefits-and-examples.pdf|url-status=live}}</ref> which allows building [[continuous integration]] and [[continuous deployment]] pipelines for testing, releasing and deploying software without the use of third-party websites/platforms. Unlike many other CI/CD tools, GitHub Actions launched with a marketplace where developers could share and reuse prebuilt actions (e.g., testing, linting, deployments). GitHub wanted to reduce reliance on third-party services and keep developers within the GitHub ecosystem. GitHub Actions provided hosted runners (Linux, Windows, macOS) that could dynamically scale, eliminating the need for self-managed build servers.
 
=== Gist ===
GitHub also operates a [[pastebin]]-style site called '''Gist''',<ref name="pastie"/> which is for [[Snippet (programming)|code snippets]], as opposed to GitHub proper, which is usually used for larger projects.{{Citation<ref needed|datename=June"pastie" 2021}}/> Tom Preston-Werner débuted the feature at a Ruby conference in 2008.<ref>{{cite conference |title = God's memory leak - a scientific treatment |authorlinkauthor-link = Tom Preston-Werner |first = Tom |last = Preston-Werner |url = https://groups.google.com/forum/#!topic/god-rb/Acyit8SlgcI |date = July 20, 2008 |conference = RubyFringe |conference-url = https://unspace.ca/rubyfringe/ |access-date = October 21, 2014 |quote = He previewed the upcoming git feature gist |archive-date = January 22, 2011 |archive-url = http://arquivo.pt/wayback/20110122130054/https://groups.google.com/forum/#!topic/god-rb/Acyit8SlgcI |url-status = live }}</ref>
 
Gist builds on the traditional simple concept of a [[pastebin]] by adding version control for code snippets, easy forking, and [[Transport Layer Security|TLS encryption]] for private pastes. Because each "gist" hasis its own Git repository, multiple code snippets can be contained in a single pastepage, and they can be pushed and pulled using Git.<ref>{{CitationCite neededweb|title=Creating gists|url=https://docs.github.com/en/github/writing-on-github/editing-and-sharing-content-with-gists/creating-gists|access-date=January2021-12-25|website=GitHub 2019Docs|language=en|archive-date=December 25, 2021|archive-url=https://web.archive.org/web/20211225194455/https://docs.github.com/en/github/writing-on-github/editing-and-sharing-content-with-gists/creating-gists|url-status=live}}</ref>
 
Unregistered users were able tocould upload Gists until FebruaryMarch 1819, 2018, when uploading gistsGists becamewas available onlyrestricted to logged-in users, reportedly to mitigate [[spamming]] on the page of recent Gists.<ref>{{Cite web|date=2018-02-1918|title=Deprecation Notice: Removing Anonymous Gist Creation|url=https://github.blog/2018-02-18-deprecation-notice-removing-anonymous-gist-creation/|access-date=2020-09-30|website=The GitHub Blog |archive-date=March 22, 2021|archive-url=https://web.archive.org/web/20210322042244/https://github.blog/2018-02-18-deprecation-notice-removing-anonymous-gist-creation/|url-status=live}}</ref>
 
Gists' [[URL]]s use hexadecimal IDs, and edits to Gists are recorded in a [[version control|revision history]], which can show the text difference of thirty revisions per page with an option between a "split" and "unified" view. Like repositories, Gists can be forked, "starred", i.e., publicly bookmarked, and commented on. The count of revisions, stars, and forks is indicated on the gist page.<ref>{{Cite web|url=https://gist.github.com/shaunlebron/746476e6e7a4d698b373/revisions|title=Build software better, together|access-date=November 20, 2021|archive-date=November 20, 2021|archive-url=https://web.archive.org/web/20211120232151/https://gist.github.com/shaunlebron/746476e6e7a4d698b373/revisions|url-status=live}}</ref>
 
=== Education program ===

GitHub has a $200,000 contract with [[U.S. Immigration and Customs Enforcement]] (ICE) for the use of their on-site product GitHub Enterprise Server.

== Developed projectsReception ==
In 2012, [[Linus Torvalds]], the original developer of Git, highly praised GitHub, stating, "The hosting of github{{sic}} is excellent. They've done a good job on that. I think GitHub should be commended enormously for making open source project hosting so easy." However, he also sharply criticized the implementation of GitHub's merging interface, saying, "Git comes with a nice pull-request generation module, but GitHub instead decided to replace it with their own totally inferior version. As a result, I consider GitHub useless for these kinds of things. It's fine for hosting, but the pull requests and the online commit editing, are just pure garbage."<ref>{{Cite magazine |last=McMillan |first=Robert |date=2012-05-11 |title=Linus Torvalds Invented Git, But He Pulls No Patches With GitHub |url=https://www.wired.com/2012/05/torvalds-github/ |url-status=live |archive-url=https://web.archive.org/web/20211205182545/https://www.wired.com/2012/05/torvalds-github/ |archive-date=December 5, 2021 |access-date=2022-01-27 |magazine=Wired |language=en-US |issn=1059-1028}}</ref><ref>{{Cite web |last=Tim Anderson |date=2021-09-06 |title=GitHub merges 'useless garbage' says Linus Torvalds as new NTFS support added to Linux kernel 5.15 |url=https://www.theregister.com/2021/09/06/github_merges_useless_garbage_says/ |url-status=live |archive-url=https://web.archive.org/web/20220127204556/https://www.theregister.com/2021/09/06/github_merges_useless_garbage_says/ |archive-date=January 27, 2022 |access-date=2022-01-27 |website=[[The Register]] |language=en}}</ref>
