Perks of using Jekyll for your projects:

• No backend/databases (yes, I consider this as a huge benefit, especially if you are just blogging)
• Static files, all you need is html + css and sometimes some simple javascript logic (for slider f.ex.);
• Markdown - it is easy to document and write posts
• Plugins - jekyll has some awesome plugins for SEO, asset management and etc.
• Hosting - it is easy to host, even github pages can host jekyll website

What packages and tools I am using

For my blogs I usually reuse the same plugins, the most useful I found are these:

"jekyll-assets"
"jekyll-seo-tag"
"image_optim"
"image_optim_pack"
"mini_magick"

CI/CD

Since github is capable of serving jekyll websites it is quite easy to setup whole pipeline for testing, building and deploying your jekyll websites.
