+cgit-pink - CGI for Git
+=======================
+
+This is a fork of cgit, an attempt to create a fast web interface
+for the Git SCM, using a built-in cache to decrease server I/O
+pressure.
+
+Installation
+------------
+
+Building cgit involves building a proper version of Git. How to do this
+depends on how you obtained the cgit sources:
+
+a) If you're working in a cloned cgit repository, you first need to
+initialize and update the Git submodule:
+
+    $ git submodule init     # register the Git submodule in .git/config
+    $ $EDITOR .git/config    # if you want to specify a different url for git
+    $ git submodule update   # clone/fetch and checkout correct git version
+
+b) If you're building from a cgit tarball, you can download a proper git
+version like this:
+
+    $ make get-git
+
+When either a) or b) has been performed, you can build and install cgit like
+this:
+
+    $ make
+    $ sudo make install
+
+This will install `cgit.cgi` and `cgit.css` into `/var/www/htdocs/cgit`. You
+can configure this location (and a few other things) by providing a `cgit.conf`
+file (see the Makefile for details).
+
+
+Dependencies
+------------
+
+* libzip
+* libcrypto (OpenSSL)
+* libssl (OpenSSL)
+
+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
+to runtime parameters, this file may also contain a list of repositories
+displayed by cgit (see `cgitrc.5.txt` for further details).
+
+The cache
+---------
+
+When cgit is invoked it looks for a cache file matching the request and
+returns it to the client. If no such cache file exists (or if it has expired),
+the content for the request is written into the proper cache file before the
+file is returned.
+
+If the cache file has expired but cgit is unable to obtain a lock for it, the
+stale cache file 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`.
+
+Online presence
+---------------
+
+* The cgit-pink homepage is hosted by cgit at
+  <https://git.causal.agency/cgit-pink/about>
+
+* Patches, bug reports, discussions and support should go to the cgit-pink
+  mailing list: <list+cgit@causal.agency>. Archives are available at:
