 == Experimental and beta APIs
 
-The PHP client offers also `experimental` and `beta` APIs for Elasticsearch.
-
-The Elasticsearch API are marked using the following convention:
-
-- **Stable** APIs should be safe to use extensively in production. 
-  Any breaking changes to these APIs should only occur in major versions and
-  will be clearly documented in the breaking changes documentation for that
-  release.
-- **Beta** APIs are on track to become stable and permanent features.
-  Caution should be exercised in their use since it is possible we’d have to make
-  a breaking change to these APIs in a minor version, but we’ll avoid this
-  wherever possible.

+- **Stable** APIs should be safe to use extensively in production. Any breaking

+- **Beta** APIs are on track to become stable and permanent features. Use them 
+  with caution because it is possible that breaking changes are made to these

 - **Experimental** APIs are just that - an experiment. An experimental API might
   have breaking changes in any future version, or it might even be removed
   entirely.
 
 All the `experimental` and `beta` APIs are marked with a `@note` tag in the
 phpdoc section of the code.
