-# Installing Your Custom Agent
+# Custom Agent Installation
 
-Your agent YAML file is a template that gets compiled to a runnable Markdown (.md) file with XML.
-
-**Good news**: You can install agents without cloning the BMAD repository using `npx bmad-method`!
-
-## Installation Options
-
-### Option 1: Interactive Install (Recommended)
+## Quick Install
 
 ```bash
-# From your BMAD project directory
-# Option A: If you have BMAD installed locally
-bmad agent-install
-
-# Option B: If you don't have BMAD cloned (works anywhere!)
+# Interactive
 npx bmad-method agent-install
 
-# Follow the prompts to select and install your agent
+# Non-interactive
+npx bmad-method agent-install --defaults
 ```
 
-**Best for**: Installing individual agents with custom naming and target selection
-
-### Option 2: Batch Install
-
-1. **Copy** your agent YAML to `{project}/.bmad/custom/src/agents/`
-2. **Run** the installer and select "Compile Agents (Quick rebuild of all agent .md files)"
-
-**Best for**: Installing multiple agents at once or rebuilding all custom agents
-
-## What Happens During Installation
-
-1. **Source**: Your agent YAML (from `custom/src/agents/`)
-2. **Compile**: Gets converted to executable .md format
-3. **Install**: Copied to `custom/agents/{agent-name}/`
-4. **Register**: Added to agent manifest and IDE commands
-5. **Backup**: Source saved to `_cfg/custom/agents/` for updates
-
-## Automatic Updates
-
-**For individual agents**:
+## Install Specific Agent
 
 ```bash
-bmad agent-install              # If BMAD installed locally
-npx bmad-method agent-install    # Works anywhere without cloning
-```
-
-**For all agents (including custom ones)**:
-
-- `bmad install` → "Compile Agents" (rebuild all agents)
-- `bmad install` → "Quick Update" (during upgrades)
-
-**Advanced Parameters**:
-
-```bash
-# Install specific agent file
+# From specific source file
 npx bmad-method agent-install --source ./my-agent.agent.yaml
 
-# Use default configuration (non-interactive, no prompts)
-npx bmad-method agent-install --defaults
+# With default config (no prompts)
+npx bmad-method agent-install --source ./my-agent.agent.yaml --defaults
 
-# Install to specific destination
-npx bmad-method agent-install --destination ./my-project
-
-# Combine parameters
-npx bmad-method agent-install --source ./my-agent.agent.yaml --defaults --destination ./my-project
+# To specific destination
+npx bmad-method agent-install --source ./my-agent.agent.yaml --destination ./my-project
 ```
 
-**When to use which**:
+## Batch Install
 
-- **Option 1**: Best for new agents or when you want custom persona names
-- **Option 2**: Best for bulk updates or when you've modified YAML files directly
+1. Copy agent YAML to `.bmad/custom/src/agents/`
+2. Run installer and select "Compile Agents"
