-## Using Skills
+## Using OpenViking Memory
 
-Once installed, agents can use these keywords during chat:
+Once skills are installed, you can use natural language to trigger OpenViking actions:
 
-| Keyword | Skill | What It Does |
-|---------|-------|--------------|
-| `ovm` | adding-memory | Extracts and stores insights from conversation |
-| `ovr` | adding-resource | Imports files/URLs into OpenViking |
-| `ovs` | searching-context | Searches stored memories and resources |
+### Storing Memories
+Say things like:
+- "**Remember this**" — after sharing something worth remembering
+- "**Save this to memory**" — to persist an insight or decision
+- "**Keep this in mind**" — to store context for future reference
 
-**Example chat flow:**
-```
-User: I prefer using vim for coding
-User: ovm
-→ Agent extracts and stores: "User prefers vim for coding"
+### Adding Resources
+Say things like:
+- "**Add this to OpenViking**" — when sharing a URL or file
+- "**Import https://example.com/docs**" — to add external knowledge
+- "**Save this resource**" — to store documents for later retrieval
 
-User: Please add https://example.com/docs
-User: ovr
-→ Agent imports and processes the URL
+### Searching Context
+Say things like:
+- "**Search my memory for...**" — to find previously stored information
+- "**What do I know about...**" — to query your OpenViking context
+- "**Find in OpenViking...**" — to search across memories and resources
 
-User: ovs What's my editor preference?
-→ Agent searches and returns: "User prefers vim for coding"
-```
+The agent will automatically detect these intents and use the appropriate OpenViking skills.
