Where to upload a .txt file to the web root of discourse installation?

For verification I need to upload a .txt file on my discourse installation. I uploaded this text file to /var/discourse folder as this is my default discourse installation path. When I accessed this file from web browser, it says file not found. I did a google search and found this thread on discourse meta forum https://meta.discourse.org/t/uploading-a-file-to-the-web-root/35626, it seems even they don’t know it.

How to do it?


Even I don’t have a clue. RoR and docker are a big mess.

Don’t they have any public folder or something where you can just upload the file?
