 For example, if you create a sphere with the core perspective "Connect everything to antiques", you'll start getting a sphere populated with concepts like "age", "antique", "collectible", "vintage", etc. all linked to content that may not obviously be about antiques.
 
+## Key Components of Spheres
+
 Spheres have:
 
 - A name or title
 - A core perspective describing the objective or theme of the sphere
 - An optional description, that is currently only for managing the sphere.
 
+## Creating and Managing Spheres

 You can create a sphere using the sphere manager tool:

 This will provide you with a list of spheres you've already created, and a form to create, edit, or delete spheres.
 
+## Effective Core Perspectives
+
+When creating a sphere, the core perspective is critical. Here are some tips for crafting effective ones:
+
+- Be specific but not limiting: "Explore connections between biology and architecture" rather than just "Biology"
+- Add a viewpoint or angle: "Analyze technology through an environmental lens" 
+- Include action words: "Discover unexpected relationships between art movements"
+- Consider cross-domain perspectives: "Connect mathematical concepts to everyday objects"
+
+## Examples of Useful Spheres
+
+Here are some examples of effective spheres:
+
+1. **Historical Parallels**: Core perspective: "Find patterns that repeat throughout history"
+2. **Innovation Inspiration**: Core perspective: "Connect natural phenomena to potential technological innovations"
+3. **Learning Framework**: Core perspective: "Organize knowledge into teachable components"
+4. **Creative Writing**: Core perspective: "Generate story elements with interconnected themes"
+
+## Using Spheres Effectively
+
+Once you've created a sphere, you can:
+
+1. **Browse Generated Concepts**: Review the AI-generated concepts to spark new ideas
+2. **Refine Your Perspective**: Edit the core perspective if you want to shift the focus
+3. **Combine Spheres**: Use multiple spheres to generate cross-domain insights
+4. **Export Content**: Save or share interesting connections for further exploration
+
+## Technical Details
+
+Behind the scenes, spheres work by providing contextual guidance to AI agents about what kinds of connections to make. The sphere's core perspective influences how content is processed, what patterns are recognized, and what new ideas are generated.
+
+Spheres are implemented using the ATProto lexicon `me.comind.sphere.core`.
