Add reading time for blog posts in Jekyll without a custom plugin.

Similar to Medium you can show the time it will take to read the blog post.

Here is the documentation to reading time

Create the file reading-time.html in your _includes and add the code shown on the doc.

Go to your _layouts/post.html and include the reading-time.html line within the header tag, before the closing paragraph. You can test to see if it shows correctly on your blog post such as Aug 29, 2020 • tom • 3 min read.

Deploy the source to master:

$ jekyll build
$ git add .
$ git commit -m "Added reading time"
$ git push -u origin master

See Jekyll without Plugins for other customizations.
