 ### Execution modes
 CLI supports 2 execution modes:
-* Interactive. In this mode CLI reads commands from terminal interactively. To start this mode just run `indy-cli` without params.
-* Batch. In this mode all commands will be read from text file or pipe and executed in series. To start this mode run `indy-cli <path-to-text-file>`. Batch mode supports the same commands as interactive mode. Note that by default if some command finishes with the error batch execution will be interrupted. To prevent this start command with `-`. For example, `-wallet create test`. In this case the result of this command will be ignored.

 ### Getting help
-The most simple way is just start cli by `indy-cli` command and put `help` command. Also you can look to [Indy CLI Design](../doc/cli-design.md) doc that contains the list of commands and architecture overview.
