Linux installation from README not working

[frafra]

Hi! Thanks for the nice tool :)

I just encountered an issue in the README file:

$ curl -L https://github.com/dirathea/sstart/releases/latest/download/sstart_Linux_x86_64.tar.gz | tar -xz
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0
  0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0
100     9  100     9    0     0     12      0 --:--:-- --:--:-- --:--:--    12

gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now

curl -L https://github.com/securestart/sstart/releases/download/v0.0.11/sstart-0.0.11-linux-amd64.tar.gz | tar -xz works just fine.
