-When you try to run “hg commit” for the first time, it is not
-guaranteed to succeed. Mercurial records your name and address with
-each change that you commit, so that you and others will later be able
-to tell who made each change. Mercurial tries to automatically figure
-out a sensible username to commit the change with. It will attempt
-each of the following methods, in order:
-
- 1. If you specify a -u option to the “hg commit” command on the
- command line, followed by a username, this is always given the
- highest precedence.
- 2. If you have set the HGUSER environment variable, this is checked next.
- 3. If you create a file in your home directory called .hgrc, with a
- username entry, that will be used next. To see what the contents
- of this file should look like, refer to section [2.7.1][11]
- below.
- 4. If you have set the EMAIL environment variable, this will be used
- next.
- 5. Mercurial will query your system to find out your local user name
- and host name, and construct a username from these
- components. Since this often results in a username that is not
- very useful, it will print a warning if it has to do this.
-
-If all of these mechanisms fail, Mercurial will fail, printing an
-error message. In this case, it will not let you commit until you set
-up a username.
-
-You should think of the HGUSER environment variable and the -u option
-to the “hg commit” command as ways to override Mercurial’s default
-selection of username. For normal use, the simplest and most robust
-way to set a username for yourself is by creating a .hgrc file; see
-below for details.
-
-##### Creating a Mercurial configuration file
-
-To set a user name, use your favourite editor to create a file called
-.hgrc in your home directory. Mercurial will use this file to look up
-your personalised configuration settings. The initial contents of your
-.hgrc should look like this.
-
- # This is a Mercurial configuration file.
- [ui]
- username = Firstname Lastname <email.address@domain.net>
-
-The “[ui]” line begins a section of the config file, so you can read
-the “username = ...” line as meaning “set the value of the username
-item in the ui section”. A section continues until a new section
-begins, or the end of the file. Mercurial ignores empty lines and
-treats any text from “#” to the end of a line as a comment.
+When you try to run “git commit” for the first time, it might not do
+exactly what you want. Git records your name and address with each
+change that you commit, (as both author and committer unless you tell
+it otherwise), so that you and others will later be able to tell who
+made each change. Git tries to automatically figure out a sensible
+name and address to attribute to both author and committer. It will
+attempt each of the following methods, in order, (stopping for each field as soon as a value is found):
+
+ 1. If you specify a --author option to the “git commit” command on
+ the command line, followed by a "Real Name <email@example.com>"
+ string, then this name and addresss will be used for the author
+ fields. The committer fields will still be determined as
+ below. This option is very helpful for when applying a commit
+ originally authored by someone other than yourself.
+ 2. If any of the GIT_AUTHOR_NAME, GIT_AUTHOR_EMAIL,
+ GIT_COMMITTER_NAME, or GIT_COMMITER_EMAIL environment variables
+ are set, then those values will be used for the corresponding
+ fields.
+ 3. If you have a file in your home directory called .gitconfig, with
+ name or email settings in the [user] section, then these values
+ will be used to set any remaining author and committer
+ fields. For more details on the contents of this file, refer to
+ section 2.7.1 below.
+ 4. If you have a file in the local repository called .git/config,
+ again with name or email settings in the [user] section, then
+ these values will be used to set any remaining author and
+ committer fields.
+ 5. If you have set the EMAIL environment variable, this will be used
+ to set author and committer email addresses if still unset.
+ 6. git will query your system to find out your real name from
+ available GECOS field and your username, hostname, and domain to
+ construct an email address, (or at least an identifier resembling
+ an email address).
+
+If all of these mechanisms fail, "git commit" will fail, printing an
+error message instructing you how to use "git config" to tell git your
+name and email address.
+
+You should think of the GIT_AUTHOR/COMMITER_NAME/EMAIL environment
+variables and the --author option to the “git commit” command as ways
+to override git’s default selection. For normal use, the simplest and
+most robust way to set your information is by creating a .gitconfig
+file, (either manually or with the "git config" command); see below
+for details.
+
+##### Creating a git configuration file
+
+To set your name and email address, just use the following commands:
+
+ git config --global user.name "Your Name"
+ git config --global user.email "you@example.com"
+
+The --global option means that this command will set global
+information, (affecting all repositories on this machine), in the
+.gitconfig file in your home directory. Alternately, you could omit
+the --global which would make the change take effect only in the local
+repository. This is convenient if you want to have different email
+addresses associated with different projects, for example.
+
+Of course, git's configuration file is a simple-to-edit plain-text
+file, so instead of using the above commands, you can also just edit
+the files directly. Use your favorite editor to create a file called
+.gitconfig in your home directory, (or if you ran the above commands
+then it will be there already). The initial contents of your
+.gitconfig should look like this.
+
+ # This is a git configuration file.
+ [user]
+ name = Your Name
+ email = you@example.com
+
+Similarly, you can make a repository-specific configuration by editing
+.git/config in the local repository. It will already have some
+sections present, (created by the "git clone"), just add a [user]
+section as above.
+
+The “[user]” line begins a section of the config file, so you can read
+the “name = ...” line as meaning “set the value of the name item in
+the user section”. This is the same notion expressed with the
+"user.name" syntax on the git-config command line. A section
+continues until a new section begins, or the end of the file. Git
+ignores empty lines and treats any text from “#” to the end of a line
+as a comment.
