-== Introduction
+== {kib} — your window into the Elastic Stack
+++++
+<titleabbrev>What is Kibana?</titleabbrev>
+++++
 
-Kibana is an open source analytics and visualization platform designed to work with Elasticsearch. You use Kibana to
-search, view, and interact with data stored in Elasticsearch indices. You can easily perform advanced data analysis
-and visualize your data in a variety of charts, tables, and maps.
+**_Explore and visualize your data and manage all things Elastic Stack._**
 
-Kibana makes it easy to understand large volumes of data. Its simple, browser-based interface enables you to quickly
-create and share dynamic dashboards that display changes to Elasticsearch queries in real time.
+Whether you’re a user or admin, {kib} makes your data actionable by providing
+three key functions:
 
-Setting up Kibana is a snap. You can install Kibana and start exploring your Elasticsearch indices in minutes -- no
-code, no additional infrastructure required.
+* **{kib} is an open-source analytics and visualization platform.**
+Use {kib} to explore your {es} data, and then build beautiful visualizations and dashboards.
+
+* **{kib} is a UI for managing {es} clusters.**
+Manage your security settings, assign user roles, monitor the Stack,
+ingest and roll up your data...the list goes on.
+
+* **{kib} is a centralized hub for our solutions.** &mdash; From log analytics to
+document discovery to SIEM, {kib} is the portal for accessing these and other capabilities.

+[[where-to-start-kibana]]
+=== Where do I start?
+
+There is no faster way to try out {kib} than with our hosted {es} Service.
+https://www.elastic.co/cloud/elasticsearch-service/signup[Sign up for a free trial]
+and start exploring data in minutes.
+
+You can also install {kib} on your own &mdash; no code, no additional
+infrastructure required. If you don’t have {es}, you’ll need that too.
+Think of Elasticsearch as the engine that stores and processes the data, with {kib} sitting on top.
+
+[float]
+[[get-data-into-kibana]]
+=== Try {kib} with our data sets and tutorials
+
+Our <<add-sample-data, sample data sets>> enable you to take {kib} for a test ride without having
+to go through the process of loading data yourself. Or, try our <<getting-started, built-in tutorials>>,
+which can help you quickly set up data flows between your app and the Elastic Stack.
+
+[role="screenshot"]
+image::images/intro-data-tutorial.png[]
+
+With both scenarios, you get data, index patterns, visualizations, and dashboards.
+<<index-patterns, Index patterns>> are key to Kibana &mdash; they identify which
+{es} indices contain the data that you want to work with.
+
+If a tutorial doesn’t exist for your data, go to the
+{beats-ref}/beats-reference.html[Beats overview] to learn about other data shippers
+in the {beats} family.
+
+[float]
+[[explore-and-query]]
+=== Explore & query
+
+Ready to dive into your data? With <<discover, Discover>>, you can explore your data and
+search for hidden insights and relationships. Ask your questions, and then
+narrow the results to just the data you want.
+
+[role="screenshot"]
+image::images/intro-discover.png[]
+
+[float]
+[[visualize-and-analyze]]
+=== Visualize & analyze
+
+A visualization is worth a thousand log lines, and {kib} provides
+many options for showcasing your data. Use <<visualize, Visualize>> to create
+classic line charts, bar graphs, pie charts, histograms, and tables
+(just to name a few).
+
+Once your visualizations are just the way you want,
+use <<dashboard, Dashboard>> to collect them in one place. A dashboard provides
+insights into your data from multiple perspectives, and you can watch the data
+change in real time.
+
+[role="screenshot"]

+
+[float]
+[[more-ways-to-visualize]]
+=== Even more ways to visualize
+
+{kib} also has these features that address specific visualization needs.
+
+* <<lens, Lens>> provides a drag-and-drop experience that helps
+you get insights from your data in just a few clicks. If there is a
+better visualization for your data, Lens suggests it, allowing
+for quick switching between visualization types.
+
+* <<canvas, Canvas>> gives you the ability to present your data in a
+visually compelling, pixel-perfect report. Give your data the “wow” factor
+needed to impress your CEO or to captivate people with a big-screen display..
+
+* <<maps, Elastic Maps>> enables you to ask (and answer) meaningful
+questions of your location-based data. Elastic Maps supports multiple
+layers and data sources, mapping of individual geo points and shapes,
+and dynamic client-side styling.
+
+* <<TSVB, TSVB>> allows you to combine
+an infinite number of aggregations to display complex data in a meaningful way.
+With TSVB, you can analyze multiple index patterns and customize
+every aspect of your visualization. Choose your own date format and color
+gradients, and easily switch your data view between time series, metric,
+top N, gauge, and markdown.
+
+[float]
+[[organize-and-secure]]
+=== Organize & secure
+
+Want to share Kibana’s goodness with other people or teams? You can do so with
+<<xpack-spaces, Spaces>>, built for organizing your visualizations, dashboards, and indices.
+Think of a space as its own mini {kib} installation &mdash; it’s isolated from
+all other spaces, so you can tailor it to your specific needs without impacting others.
+
+You can even choose which features to enable within each space. Don’t need
+Machine learning in your “Executive” space? Simply turn it off.
+
+[role="screenshot"]
+image::images/intro-spaces.jpg[]
+
+You can take this all one step further with Kibana’s security features, and
+control which users have access to each space. {kib} allows for fine-grained
+controls here, so you can give a user read-only access to
+dashboards in one space, but full access to all of Kibana’s features in another.
+
+[float]
+[[manage-all-things-stack]]
+=== Manage all things Elastic Stack
+
+<<management, Management>> provides guided processes for managing all
+things Elastic Stack &mdash; indices, clusters, licenses, UI settings, index patterns,
+spaces, and more. Want to update your {es} indices? Set user roles and privileges?
+Turn on dark mode? Kibana has UIs for all that.

+[[extend-your-use-case]]
+=== Extend your use case...or add a new one
+
+As a hub for our https://www.elastic.co/products/[solutions], {kib}
+can help you find security vulnerabilities,
+monitor performance, and address your business needs. Get alerted if a key
+metric spikes. Detect anomalous behavior or forecast future spikes. Root out
+bottlenecks in your application code. Kibana doesn’t limit or dictate how you explore your data.
+
+[float]
+[[try-kibana]]
+=== Give Kibana a try
+
+Grab an installation of {kib} and start working with your data.
+Our <<tutorial-build-dashboard, Getting Started>> and in-product guidance can
+help you get up and running, faster. Use the Help menu for any questions or
+feedback you might have.
