To test, I created a library on github, access address: https://github.com/zibuyule/test2.
On readthedocs.org entered my github account and build the latest version.
On readthedocs.org My address is: https://readthedocs.org/projects/test-zibuyule/.
Click on the "read the document" shows 404 error page. Try the afternoon still not been resolved.
Who have successfully posted on readthedocs.org, whether under the advice. I feel this thing is still very good, hope to use it.
Thank you
I have faced the same issue. Just put the .md documentation files inside a docs folder in your repository and it will work.
Extract from their documentation:
We will look inside a doc or docs directory first, and then default to the top-level of your documentation.
It seems that it is incorrect - top-level folder is not scanned for .md files, so you have to use docs folder
