org-preview-html-mode is an Emacs minor mode for org mode that automatically uses the built-in eww browser to preview the current org file. The preview is updated every time the org file is saved.
The preferred way of installing this package is using MELPA.
If you want to do it in old fashioned way, download it and place the org-preview-html.el file in a directory on your emacs load path and require it.
The recommended, fully OS independent way to include a directory to your load path is to use this code with the appropriate directory name:
(add-to-list 'load-path
(concat user-emacs-directory
(convert-standard-filename "elisp/")))Open an org file and execute M-x org-preview-html-mode. An eww preview
window is shown next to the org file.
Then every time the org file saved, the eww buffer is updated.
