Hi Stepan,
1. Why exists second branches with all documentation? I mean they looks good together, why need to separate?
Because finally the docs should not be in the repo (unfortunately) but on readme.io.
There is a task for that: https://issues.apache.org/jira/browse/IGNITE-9523
Also, one place when i found this branch it is this thread, not in jira, not in a github
Added the link in the jira.
2. Examples in readme.md have better look in php/examples. I mean php/examples have one set of examples and readme have second one, they not match and they both looks good. Why doesn't add readme examples in php/examples?
Examples in readme.md are more like code snippets (mostly not big) intended to help better understanding the usage of the client along the reading. Examples in php/examples are more meaningful and fully cover the examples in readme.md.
Thanks, -Alexey
