-A powerful telemetry framework
 
-## Usage
-The `snap-telemetry` package installs `snaptel` in `/usr/local/sbin/snaptel`, and `snapteld` in `/usr/local/sbin/snapteld`. Either ensure `/usr/local/bin:/usr/local/sbin` is in your path, or use fully qualified filepath to the `snaptel`/`snapteld` binary:
+The command-line interface (CLI) for Snap - a powerful telemetry framework
+
+## General information
+
+### Snap CLI on top of REST API V1
+
+The `snaptel` which bases on [REST API V1](REST_API_V1.md) is available in the main Snap repo, as a part of
+[Snap releases](https://github.com/intelsdi-x/snap/releases) and `snap-telemetry` package.
+
+
+### Snap CLI on top of REST API V2
+
+The _alpha version_ of `snaptel` which relays on [Snap API Go client](https://github.com/intelsdi-x/snap-client-go) talking to [REST API V2](REST_API_V2.md) is available in a separate repo [snap-cli](https://github.com/intelsdi-x/snap-cli).
+
+The separated Snap API client and CLI support [Swagger Open API Specification](https://swagger.io/specification). The Snap API client can be autogenerated based on provided [swagger.json](https://github.com/intelsdi-x/snap/swagger.json) in different languages/frameworks supported by [swagger-code-generator](https://github.com/swagger-api/swagger-codegen#swagger-code-generator) - to generate a new Snap API client in your preferred language, please follow the instruction provided there.

+  - [snap-cli](https://github.com/intelsdi-x/snap-cli)
+
+
+**Important:**
+_For Snap daemon running in the [Tribe mode](TRIBE.md), please use `snaptel` which bases on REST API V1 since Tribe commands
+are not yet supported by REST API V2_
