-For MVP: Add descriptions and links to existing solutions content with focus on tutorials where appropriate. 
+Elastic solutions--Security, Observability, and Search--are loaded with features
+and functionality to help you get value and insights from your data.
+{fleet-guide}[Elastic Agent] and {integrations-docs}[Elastic integrations] can help.
+
+When you use integrations with solutions, you have an integrated experience that offers
+easier implementation and decreases the time it takes to get insights and value from your data.
