+Deployment
+- Before deployment there is something called collections which can be defined in `_config.yml` in root of site so there is site.data, site.posts which are predefined so for more like site.authors type following in `_config.yml`
+```yml
+collections:
+  authors:
+    output: true
+```
+By default it wont output to page so using this when clicked on author it will redirect to its page
+More refer to https://jekyllrb.com/docs/step-by-step/09-collections/
+- Now going back to root of project so type `cd ..`. as jekyll is installed and all the versions are locked so in order to serve or build with those versions instead of system ones use `bundle exec jekyll serve` instead of `jekyll serve`. this will restrict the enviroment to use gems set in Gemfile.
+- Some other important plugins
+   -  jekyll-sitemap - Creates a sitemap file to help search engines index content
+    - jekyll-feed - Creates an RSS feed for your posts
+    - jekyll-seo-tag - Adds meta tags to help with SEO
+- in Gemfile
+```
+source 'https://rubygems.org'
+
+gem "jekyll"
+
+group :jekyll_plugins do
+  gem "jekyll-sitemap"
+  gem "jekyll-feed"
+  gem "jekyll-seo-tag"
+end
+```
+- in `_config.yml`
+```yml
+plugins:
+  - jekyll-feed
+  - jekyll-sitemap
+  - jekyll-seo-tag
+```
+now install by `bundle update`
+in `_layouts/default.html`
+add these tags
+```html
+<!doctype html>
+<html>
+  <head>
+    <meta charset="utf-8">
+    <title>{{ page.title }}</title>
+    <link rel="stylesheet" href="/assets/css/styles.css">
+    {% feed_meta %}
+    {% seo %}
+  </head>
+  <body>
+    {% include navigation.html %}
+    {{ content }}
+  </body>
+</html>
+```
