4 <h2>What is a repository?</h2>
5
6 <p>When you use a version control system to keep track of your changes to
7 a set of files, there are two different concepts you're dealing with:
8 a <i>working copy</i> and a <i>repository</i>.</p>
9
10 <p>A <i>working copy</i> is just a folder with your project's files in it. It
11 contains the versions of the files that you are working with now.
12 <ul><li>EasyMercurial's &ldquo;My Work&rdquo; tab shows you which files you have been working on in your current working copy.</li></ul></p>
13
14 <p>A <i>repository</i> is a record of the entire history of your project. When
15 change something in the working copy, you can then commit it to the
16 repository and your change gets added to the history.
17 <ul><li>EasyMercurial's &ldquo;History&rdquo; tab shows you the changes that have been committed to your project's history in its repository.</li></ul></p>
18
19 <p>You can also go back and grab an older version from the repository if
20 you find you need it. (If you do this, then the working copy will be
21 updated so as to contain that older version rather than the most
22 recent one.)</p>
23
24 <p>Older centralised version control systems use a separate database for
25 the repository. But with a distributed version control system such as
26 Mercurial, the repository &ndash; the entire history of your project files
27 &ndash; is stowed into a special folder inside the working copy on your
28 hard drive. Every change you commit gets added to the history in that
29 hidden folder. (The history is compressed, so it doesn't take as much
30 space as you might imagine.)</p>
31
32 <p>The term <i>remote repository</i> simply refers to a repository related to
33 your local one, but stored on another computer somewhere else. Often
34 this may be a &ldquo;master copy&rdquo; of your project stored on a server
35 elsewhere, which you and your collaborators can use to keep up with
36 each other's work, or which you can use to make your work public, or
37 simply use as a private backup.</p>
