-cgit - CGI for Git
-==================
-
-This is 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).
-
-If you'd like to compile without Lua support, you may use:
-
-    $ make NO_LUA=1
-
-And if you'd like to specify a Lua implementation, you may use:
-
-    $ make LUA_PKGCONFIG=lua5.1
-
-If this is not specified, the Lua implementation will be auto-detected,
-preferring LuaJIT if many are present. Acceptable values are generally "lua",
-"luajit", "lua5.1", and "lua5.2".
-
-
-Dependencies
-------------
-
-* libzip
-* libcrypto (OpenSSL)
-* libssl (OpenSSL)
-* optional: luajit or lua, most reliably used when pkg-config is available
-
-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 homepage is hosted by cgit at <https://git.zx2c4.com/cgit/about/>
-
-* Patches, bug reports, discussions and support should go to the cgit
-  mailing list: <cgit@lists.zx2c4.com>. To sign up, visit
-  <https://lists.zx2c4.com/mailman/listinfo/cgit>

+## cgitext - CGI for Git extension by Saya Andy
+
+This is a custom expansion to cgit. Its most prominent changes by now are:
+
+* CI/CD tab, linking to an external service on ref pages by using template. The Jenkins plugin is added to support a scenario when a ref lacks a pipeline.
+
+The original cgit project is hosted at [git.zx2c4.com](https://git.zx2c4.com/cgit/about/)
