I’m not sure how to install discourse myself, can someone help me here?
Follow these instructions: discourse/docs/INSTALL-cloud.md at main · discourse/discourse · GitHub
If you can’t handle that, then you can get me to install it for you: https://www.literatecomputing.com/product/discourse-lite-install/
Hello there, I’ve read everything there many times but I just don’t get how it works nor I can understand it 
It be great if you could help me install one but would it cost?
As @pfaffman mentions in his post above:
If so, then yes I’d appreciate it if he could help me for the installation.
It seems like I can’t private message him, any ideas?
The idea is that you’d create accounts at digital ocean and mailgun and place an order on my site.
