                        cgit - cgi for git
 
 
 This is an attempt to create a fast web interface for the git scm, using a
 builtin cache to decrease server io-pressure.
 
 
 Installation
 
-  $ make gitsrc=<path>
+  $ make
   $ su
-  $ make prefix=<path> install
+  $ make install
 
+This will install cgit.cgi and cgit.css into "/var/www/htdocs/cgit".
 
-Default value for gitsrc is "../git", and this directory should contain the
-git sources.
+Note: The initial "make" will create a submodule 'git' and clone the git
+repository at git://git.kernel.org/pub/scm/git/git.git in it. If you
+already have a local git git repository that you want to use as origin
+for the submodule, run
 
-Default value for prefix is "/var/www/htdocs/cgit". This directory will 
-contain "cgit.cgi" and "cgit.css" after 'make install'.
+  $ git clone -s <path-to-git-repo> git
+  $ ./submodules.sh -u
 
-After installation, httpd.conf probably must be updated with a Directory-
-section for cgit, possibly something like this:
+before running "make".
+
+
+Dependencies
+
+  -git (1.5.2-rc0 or newer, due to git submodule) installed
+  -zip lib
+  -crypto lib
+  -openssl lib
+
+
+Apache configuration
+
+A new Directory-section must probably be added for cgit, possibly something
+like this:
 
   <Directory "/var/www/htdocs/cgit/">
       AllowOverride None
       Options ExecCGI
       Order allow,deny
       Allow from all
   </Directory>
 
 
 Runtime configuration
 
 The file /etc/cgitrc is read by cgit before handling a request. In addition

 A template cgitrc is shipped with the sources, and all parameters and default

 The cache

 the content for the request is written into the proper cachefile before the
 file is returned.

+If the cachefile has expired but cgit is unable to obtain a lock for it, the
 stale cachefile is returned to the client. This is done to favour page
 throughput over page freshness.
 
 The generated content contains the complete response to the client, including
 the http-headers "Modified" and "Expires".

+
+The mis(sing) features
+
+Submodule links in the directory listing page have a fixed format per
+repository. This should probably be extended to a generic map between
+submodule path and url.
