+# CodeCompanion + Ollama Integration Summary
+
+## What Was Done
+
+Your CodeCompanion configuration has been updated to support Ollama models alongside your existing Claude adapters. Here's what changed:
+
+### 1. **Added Ollama Adapter** (`lua/shelbybark/plugins/codecompanion.lua`)
+   - Reads `OLLAMA_ENDPOINT` environment variable
+   - Defaults to `http://localhost:11434` if not set
+   - Uses `mistral` as the default model (configurable)
+
+### 2. **Added Ollama Keymaps**
+   - `<leader>cll` - Toggle Ollama chat (normal and visual modes)
+   - Works alongside existing Claude keymaps
+
+### 3. **Created Documentation**
+   - `docs/OLLAMA_SETUP.md` - Comprehensive setup guide
+   - `docs/OLLAMA_QUICK_SETUP.md` - Quick reference for other machines
+   - `docs/ollama_env_example.sh` - Shell configuration example
+
+## How It Works
+
+### On Your Main Machine (with Ollama)
+```bash
+# Ollama runs locally, CodeCompanion uses http://localhost:11434 by default
+nvim
+# Press <leader>cll to chat with Ollama
+```
+
+### On Other Machines (without Ollama)
+```bash
+# Set environment variable to your Ollama server's Tailscale IP
+export OLLAMA_ENDPOINT="http://100.123.45.67:11434"
+nvim
+# Press <leader>cll to chat with Ollama via Tailscale
+```
+
+## Key Features
+
+✅ **Network Access**: Access Ollama from any machine on your Tailscale network
+✅ **Fallback Support**: Keep Claude as primary, use Ollama as alternative
+✅ **Easy Switching**: Use keymaps to switch between models instantly
+✅ **Environment-Based**: Configuration adapts to each machine automatically
+✅ **No Code Changes**: Just set an environment variable on other machines
+
+## Next Steps
+
+### 1. **On Your Ollama Server Machine**
+
+Ensure Ollama is exposed to the network:
+```bash
+# Check current Ollama binding
+ps aux | grep ollama
+
+# If needed, set it to listen on all interfaces
+sudo systemctl edit ollama
+# Add: Environment="OLLAMA_HOST=0.0.0.0:11434"
+# Save and exit, then:
+sudo systemctl restart ollama
+
+# Find your Tailscale IP
+tailscale ip -4
+```
+
+### 2. **On Other Machines**
+
+Add to your shell config (`~/.zshrc`, `~/.bashrc`, etc.):
+```bash
+export OLLAMA_ENDPOINT="http://YOUR_TAILSCALE_IP:11434"
+```
+
+### 3. **Test It**
+
+```bash
+# Verify connection
+curl http://YOUR_TAILSCALE_IP:11434/api/tags
+
+# Start Neovim and press <leader>cll
+nvim
+```
+
+## Configuration Details
+
+### Ollama Adapter Settings
+- **Location**: `lua/shelbybark/plugins/codecompanion.lua` (lines 35-45)
+- **Default Model**: `mistral` (change to your preference)
+- **Endpoint**: Read from `OLLAMA_ENDPOINT` env var
+- **Fallback**: `http://localhost:11434`
+
+### Available Models to Try
+- `mistral` - Fast, good quality (recommended)
+- `neural-chat` - Optimized for conversation
+- `dolphin-mixtral` - Larger, higher quality
+- `llama2` - General purpose
+- `orca-mini` - Very fast, lightweight
+
+Pull models with: `ollama pull <model-name>`
+
+## Troubleshooting
+
+### Connection Issues
+```bash
+# Test Ollama is running
+curl http://localhost:11434/api/tags
+
+# Test Tailscale connectivity
+ping 100.x.x.x  # Use your Tailscale IP
+
+# Check Ollama is bound to network
+sudo netstat -tlnp | grep 11434
+```
+
+### Model Issues
+```bash
+# List available models
+curl http://localhost:11434/api/tags | jq '.models[].name'
+
+# Pull a model
+ollama pull mistral
+```
