Files that start with an underscore are missing
If your GitHub Pages site isn't publishing certain files then you might need to reformat their titles. If you are using Jekyll you can create a .nojekyll file or edit the _config.yml file to publish these files.
By default, Jekyll does not build any files or directories that
- are hidden or used for backup (indicated by names that start with
.or#, or that end with~); - contain site content (indicated by names that start with
_); or - are excluded in the site configuration.
To work around this behavior, you can
- include a .nojekyll file in the root path to turn off Jekyll;
- use the include directive in your _config.yml to specify files that should not be ignored; or
- do not use file or directory names that start with an underscore (
_), period (.), or hash symbol (#), or that end with a tilde (~).
If you add a .nojekyll file, your source files will be published without any modifications. Do not use this option if you want Jekyll to process them.
