+#### Examples:
+
+
+__1:__  A simple example for showing facet as tabs.
+
+```jsx
+  const DummySearcher = require('../../src/components/DummySearcher').default;
+  const QueryResponse = require('../../src/api/QueryResponse').default;
+  const sampleFacets = require('../sampleData/Facets').default;
+
+  const queryResponse = new QueryResponse();
+  queryResponse.facets = [
+    sampleFacets.regionFacet,
+  ];
+
+  <DummySearcher
+    defaultQueryResponse={queryResponse}
+  >
+    <FacetTabs facetName = "region" />
+  </DummySearcher>
+```
+
+__2:__  Example for showing facet tabs by passing in a facet instead of facet name.
+
+```jsx
+  const sampleFacets = require('../sampleData/Facets').default;
+
+  <FacetTabs facet = {sampleFacets.regionFacet} />
+```
+
+__3:__  Example for showing facet tabs by passing in a facet and a background color.
+
+```jsx
+  const sampleFacets = require('../sampleData/Facets').default;
+
+  <FacetTabs facet={sampleFacets.regionFacet} backgroundColor='lightgray' />
+```
