usage

upload file/directory

> export CHAIN_TYPE=<your CHAIN_TYPE>
> git clone https://github.com/MOSSV2/dimo-sdk-go.git
> cd example/upload
> go build
# if sk not set, will generate a new key, model means upload model or regualr file/dir
> ./upload --model=false --sk=<your secret key> --path=<your local file/dir path>
# example, upload file

download file/directory

> export CHAIN_TYPE=<your CHAIN_TYPE>
> cd example/download
> go build
# if sk not set, will generate a new key, model means upload model or regualr file/dir
> ./download --model=false --sk=<your secret key>  --name=<file name> --path=<your local file/dir path to save>
# example, upload file
