+### Deployment
+GitHub Pages [does not support]((https://help.github.com/articles/adding-jekyll-plugins-to-a-github-pages-site/)) custom plugins. The tag list and tag pagination are built using custom plugins. There are several options to avoid any errors while deploying to production.
+* Run ````bundle exec jekyll build```` or ````npm run build```` and manually add the contents of the ```_site``` folder to the ```gh-pages``` branch.
+* Link the repository to [Netlify](https://www.netlify.com/). Netlify will then rebuild the theme every time a commit is pushed to the repo.
+* Finish setting up the [s3-website](https://github.com/klaemo/s3-website) package that is already included in the theme. This would deploy the theme to AWS S3 when ```npm run deploy``` is run.

 ### Source Code
 The source code is broken down to make finding what you need as easy as possible. Almost everything runs through ````gulpfile.js````, so you will need to run ````npm install```` on your command line before doing any additional development. You can then run ````gulp```` or ````npm run gulp```` to compile everything.
