## CLI

Mainflux CLI makes it easy to manage users, things, channels and messages.

CLI can be downloaded as separate asset from [project realeses](https://github.com/mainflux/mainflux/releases) or it can be built with `GNU Make` tool:

```
make cli
```

which will build `mainflux-cli` in `<project_root>/build` folder.

Executing `build/mainflux-cli` without any arguments will output help with all available commands and flags:

```
