# Sitemap.xml Generator is a Jekyll plugin that generates a sitemap.xml file by
|
||||
# traversing all of the available posts and pages.
|
||||
#
|
||||
# How To Use:
|
||||
# 1) Copy source file into your _plugins folder within your Jekyll project.
|
||||
# 2) Change modify the url variable in _config.yml to reflect your domain name.
|
||||
# 3) Run Jekyll: jekyll --server to re-generate your site.
|
||||
#
|
||||
# Variables:
|
||||
# * Change SITEMAP_FILE_NAME if you want your sitemap to be called something
|
||||
# other than sitemap.xml.
|
||||
# * Change the PAGES_INCLUDE_POSTS list to include any pages that are looping
|
||||
# through your posts (e.g. "index.html", "archive.html", etc.). This will
|
||||
# ensure that right after you make a new post, the last modified date will
|
||||
# be updated to reflect the new post.
|
||||
# * A sitemap.xml should be included in your _site folder.
|
||||
# * If there are any files you don't want included in the sitemap, add them
|
||||
# to the EXCLUDED_FILES list. The name should match the name of the source
|
||||
# file.
|
||||
# * If you want to include the optional changefreq and priority attributes,
|
||||
# simply include custom variables in the YAML Front Matter of that file.
|
||||
# The names of these custom variables are defined below in the
|
||||
# CHANGE_FREQUENCY_CUSTOM_VARIABLE_NAME and PRIORITY_CUSTOM_VARIABLE_NAME
|
||||
# constants.
|
||||
#
|
||||
# Notes:
|
||||
# * The last modified date is determined by the latest from the following:
|
||||
# system modified date of the page or post, system modified date of
|
||||
# included layout, system modified date of included layout within that
|
||||
# layout, ...
