- Only bmad-method is registered in npm registry, not bmad
- Clarify that bmad command works locally when BMAD is installed
- Update installation guides to use correct package name

Ensures users don't get 'package not found' errors when trying npx bmad

+## Installing from Custom Locations
+
+Use the `-p` / `--path` option to install agents from any location:
+
+```bash
+# Install agent from a custom folder (expert agent with sidecar)
+bmad agent-install -p path/to/my-agent
+
+# Install a specific .agent.yaml file (simple agent)
+bmad agent-install -p path/to/my-agent.agent.yaml
+
+# Install with defaults (skip all prompts)
+bmad agent-install -p path/to/my-agent -d
+
+# Install to a specific target project
+bmad agent-install -p path/to/my-agent -t /path/to/target/project
+```
+
+This is useful when:
+
+- Your agent is in a non-standard location (not in `.bmad/custom/agents/`)
+- You're developing an agent outside the project structure
+- You want to install from an absolute path

 ## Creating Your Own
 
-Place your `.agent.yaml` files in `.bmad/custom/agents/`. Use the reference agents as templates.
-
-Key sections in an agent YAML:
-
-- `metadata`: name, title, icon, type
-- `persona`: role, identity, communication_style, principles
-- `prompts`: reusable prompt templates
-- `menu`: numbered menu items
-- `install_config`: personalization questions (optional, at end of file)
-
-See the reference agents for complete examples with install_config templates and XML-style semantic tags.
+Use the BMB agent builder to craft your agents. Once ready to use yourself, place your `.agent.yaml` files or folder in `.bmad/custom/agents/`.
