This repository instructs you how to display your pdf file in github. Like this
All the things can be done with the help of GitHub Pages.
What you need to do includes:
Upload your pdf files to the github repository in your convinient way. For example, I upload a test.pdf to “Mahsh/DisplayPDF” repository. In order to display the pdf files in your browser, make sure upload your files with “master” or “gh-pages” branch.
Edit the settings of your repository. For the “GitHub Pages” term, select the source with “master branch” or “gh-pages branch” then save.
The link of your file in the form of “https:// YourAccountName.github.io/ +RepoName+FileName “. For instance, the “test.pdf” that I uploaded in the first step has the link “https://mahsh.github.io/DisplayPDF/test.pdf”.
Enjoy it!
