 == (Re)installing an older version that's no longer installed == #install
 If you want to go back to an older version after you've already uninstalled it, or to install an older version of a port that predates when you first installed it, you can do so by manually downloading the older version of the portfile and any associated files from the MacPorts Subversion repository.
+If you want to go back to an older version after you've already uninstalled it, or to install an older version of a port that predates when you first installed it, you can do so by manually downloading the older version of the portfile and any associated files from the MacPorts Git repository.
 === Step 1: '''Find the right revision''' ===
+=== Step 1: '''Find the right commit''' ===
 To install an older version of the port, you'll have to get the necessary files from the repository.
+[browser:trunk/dports Browse the repository] to find the directory of the port you want, then use the Revision Log link in the upper right to find the older version that you want to install.
+For example, if you wanted to install the older 8.4.16 version of tcl, browse to the [browser:trunk/dports/lang/tcl lang/tcl] directory and look at its [log:trunk/dports/lang/tcl revision log].
+Here you'll note that tcl was updated to 8.5.0 in !r32235, so you want the revision before that, which was !r30810.
+(You can also just subtract one from the revision you found, e.g. !r32235 - 1 = !r32234.)
+If desired, you can click the [browser:trunk/dports/lang/tcl@30810 @30810] link in the revision log (not the [30810] link) to see the directory as it existed in that revision.
+[https://github.com/macports/macports-ports Browse the repository] to find the directory of the port you want, then use the History button in the upper right to find the older version that you want to install.
+For example, if you wanted to install the older 8.4.16 version of tcl, browse to the [https://github.com/macports/macports-ports/tree/master/lang/tcl lang/tcl] directory and look at its [https://github.com/macports/macports-ports/commits/master/lang/tcl history].
+Here you'll note that tcl was updated to 8.5.0 in !345f962, so you want the commit before that, which was !686ea4f.
+If desired, you can click the [https://github.com/macports/macports-ports/tree/686ea4fa0fddeb03fdf2fc04dded68e05181bc95/lang/tcl <>] link in the history (not the !686ea4f link) to see the directory as it existed in that commit.
 === Step 2: '''Get the port directory''' ===
 In the Terminal, using the revision number, port category and port name, check out the port's directory at the desired revision using the `svn` command:
+In the Terminal, using the commit hash, port category and port name, check out the port's directory at the desired commit using the `git` command:
 {{{
+$ svn checkout -r 30810 https://svn.macports.org/repository/macports/trunk/dports/lang/tcl
+$ git clone --single-branch https://github.com/macports/macports-ports.git
+$ cd macports-ports
+$ git checkout 686ea4fa0fddeb03fdf2fc04dded68e05181bc95
 }}}
 This creates a "tcl" directory in your current location, and populates that with everything the port needs to build.
 Replace "30810" and "lang/tcl" with the correct revision and category/portname for the port you're interested in.
+This creates a "macports-ports" directory in your current location, and populates that with a complete copy of the ports tree as it existed at the specified point in history.
+Replace "!686ea4fa0fddeb03fdf2fc04dded68e05181bc95" with the commit you're interested in.
 Note:
 Subversion is included with Mac OS X 10.5 and later but you may want to get a newer version by installing the subversion port;
 Mac OS X 10.4 does not include subversion, so users of that system must install the port:
+Git is included with Xcode 4.1 and later but you may want to get a newer version by installing the git port;
+Xcode 4.0 and earlier do not include git, so users of those versions must install the port:
 {{{
 $ sudo port install subversion
+$ sudo port install git
 }}}

 === Step 3: '''Build the downloaded port''' ===
 Finally, change to the directory you checked out with Subversion (which contains the Portfile) and install the port, omitting the port name:

 {{{port info php5}}} shows it to be first in the '''lang''' category, so it would be located in lang/php5.
 After browsing [log:trunk/dports/lang/php5 php5's history], 5.3.0 was introduced in r53563 which means the previous revision, r53555, was the last update for 5.2.10.  With this information, we can run:
