  add new line
  add dedicated vc15 starter scripts
  vc15 support, more to follow
  add vswhere
  add lemon to the list
  beta2 now
  prepare for beta1

 # Overview
 
-The PHP SDK 2.0 is compatible with PHP 7.0 and above. The compatibility with older versions, eq. php-sdk-binary-tools-20110915.zip available from windows.php.net previously, is kept. Though, some irrelevant tools was removed. Newer tools are now available, better workflows are now possible. The toolset consists on a mix of the hand written scripts, selected MSYS2 parts and standalone programs.
+The PHP SDK 2.0 is compatible with PHP 7.0 and above. The compatibility with [older versions](http://windows.php.net/downloads/php-sdk/php-sdk-binary-tools-20110915.zip "php-sdk-binary-tools-20110915.zip") is kept, also available from the [legacy branch](https://github.com/OSTC/php-sdk-binary-tools/tree/legacy). The toolset was significantly revamped. Newer tools are now available, better workflows are now possible.
