To build locally:

• Run jekyll build in the source folder.
• Copy contents of _site into the compiled folders' blog directory. The compiled folder is an entirely different directory, i.e., not a subdir in the source folder. This should map to the gh-pages branch in GitHub pages.
• In the compiled folder, copy the index.html file from the blog directory into the root of the folder.
• Also copy the _sass folder from the source folder to a _sass folder in the compiled directory. You need this if there have been style related changes, e.g., if you have changed minima.scss.
