 # Low-level PHP binding for libvips 
 
-This extension lets you use the libvips image processing library from PHP. It is
-intentionally very low-level. Modules such as
-https://github.com/jcupitt/php-vips try to layer a nice API on
-top of this. 
-
-libvips is fast and it can work without needing to have the 
-entire image loaded into memory. Programs that use libvips don't
-manipulate images directly, instead they create pipelines of image processing
-operations starting from a source image. When the end of the pipe is connected
-to a destination, the whole pipeline executes at once, streaming the image
-in parallel from source to destination in a set of small fragments. 
-
-See the [benchmarks at the official libvips
-website](http://www.vips.ecs.soton.ac.uk/index.php?title=Speed_and_Memory_Use).
-There's a handy blog post explaining [how libvips opens
-files](http://libvips.blogspot.co.uk/2012/06/how-libvips-opens-file.html)
-which gives some more background.
+This extension lets you use the libvips image processing library from PHP 7. It 
+is intentionally very low-level: modules such as 
+https://github.com/jcupitt/php-vips try to layer a nice API on top of this.
+
+libvips is fast and needs little memory. The [`vips-php-bench`](
+https://github.com/jcupitt/php-vips-bench) repository tests
+`php-vips` against `imagick` and `gd`: on that test, and on my laptop,
+`php-vips` is around four times faster than `imagick` and needs 10 times less
+memory. 
 
 ### Example
 
 ```php
 #!/usr/bin/env php
 <?php
-if (!extension_loaded("vips")) {
-    dl('vips.' . PHP_SHLIB_SUFFIX);
-}
 
 $x = vips_image_new_from_file($argv[1])["out"];
 $x = vips_call("invert", $x)["out"];
 vips_image_write_to_file($x, $argv[2]);
-?>
 ```
 
 Almost all operations return an array of result values. Usually there is a
 single result called `"out"`.
 
 Use `vips_call()` to call any operation in the vips library. There are around 
-around 300 operations available, see the vips docs for an
-introduction:
+around 300 operations available, see the vips docs for an introduction:
 
 http://www.vips.ecs.soton.ac.uk/supported/current/doc/html/libvips/
 
 Arguments can be long, double, image, array of long, array of double or array
 of image. The final argument to `vips_call()` is an array of operation options. 
 
-### Preparation
+`php-vips` layers a nice API, including full docs, on top of this extension, 
+see:
 
-PHP is normally built for speed and is missing a lot of debugging support you
-need for extension development. For testing and dev, build your own php. 
-I used 7.0.11 and configured with:
+https://github.com/jcupitt/php-vips
 
-```
-$ ./configure --prefix=/home/john/vips --enable-debug --enable-maintainer-zts \
-    --enable-cgi --enable-cli --with-readline --with-openssl --with-zlib \
-    --with-gd --with-jpeg-dir=/usr --with-libxml-dir=/usr
-```
+### Installing
 
-You'll need libvips 8.0 or later, including all the headers for
-development.  On linux, install with your package manager.  On OS X,
-install with `brew` or MacPorts. For Windows, download a zip from the
-libvips website, or build your own.
+On OS X, use `brew install php70-vips` to install the libvips library, php and
