#122 fix readme's command ( pip install -r requirements.txt is not working )

[hideokamoto]

pip install -r requirements.txt is not working.

$ pip install -r requirements.txt
Could not open requirements file: [Errno 2] No such file or directory: 'requirements.txt'

I thinks this command should be pip install -r save/requirements.txt.
Thanks!

Thanks for the change, looks good, but we need you to sign the CLA in order to merge this.

Also, please note that this repository is no longer maintained as such. We've moved the dashboards to the main elastic/beats repo in the etc/kibana folder of each beat.

I'm sorry to late.
I signed the CLA now.

And where is etc/kibana folder in the elastic/beats repos...
Is etc/kibana dir not master branch?

Thanks
