 For manipulations with configs, [jq](https://jqlang.github.io/jq/) is needed, it can be found in repositories of almost all popular Linux

+### How it works
+
+With current configs, *XRay* creates a [grpc](https://en.wikipedia.org/wiki/GRPC) tunnel between the client (your laptop, phone etc.) and
+the server (your VPS). For the censor the tunnel looks like a usual connection to a site. The server responses to https requests as some
+popular site thus it is not suspicious for an active probing. On the client side *XRay* creates a socks proxy which can be used by your
+web browser, telegram or TorBrowser like that:
