@satk0 you seem to be using wrong master branch- instead of kuskoman/logstash-exporter, you are using your satk0/logstash-exporter main branch. could you fix that?

[kuskoman]

@satk0 also, your script seems to be adding whitespaces in some empty lines

[kuskoman]

I think we are duplicating the section. we should simplify it to just one repetition. or, instead, provide more detailed information

[satk0]

Good point. I will just stick to only one repetition.

In my newest commit I deleted the "Example Usage" section. Maybe this section could actually be used to show an example logstash exporter usage scenario? I think it might be helpful for any newcomer.

[kuskoman]

i think that running the application is documented enough, but if you want you can create examples dir
personally i dont think it is needed, people looking for this tool usually know what they are doing :p
