+
9
+| Benefit | Description |
10
+|---------|-------------|
11
+| **Complete Privacy** | All data stays on your machine |
12
+| **Free** | No API costs (with local LLM) |
13
+| **Offline** | Works without internet |
14
+| **Full Control** | Customize everything |
15
+| **No Rate Limits** | Use as much as you want |

+## 📋 Prerequisites
20
+
21
+- Docker (v20.10+)
22
+- Docker Compose (usually included with Docker)
23
+- 4GB+ RAM (for local LLM)
24
+- NVIDIA GPU (optional, for faster LLM inference)
25
+
26

27
+
28
+## 🚀 Quick Start
29
+
30
+### Option 1: Backend Only (Use Cloud APIs)
31
+
32
+```bash
33
+cd opengrammar/opengrammar
34
+
35
+# Create environment file
36
+cat > .env << EOF
37
+PORT=8787
38
+NODE_ENV=production
39
+GROQ_API_KEY=your_groq_key
40
+OPENAI_API_KEY=your_openai_key
41
+EOF
42
+
43
+# Start backend
44
+docker-compose up -d opengrammar-backend
45
+
46
+# Check status
47
+docker-compose ps
48
+
49
+# View logs
50
+docker-compose logs -f opengrammar-backend
51
+```
52
+
53
+### Option 2: Backend + Ollama (Local LLM)
54
+
55
+```bash
56
+cd opengrammar/opengrammar
57
+
58
+# Start everything (requires NVIDIA GPU)
59
+docker-compose --profile local-llm up -d
60
+
61
+# Check status
62
+docker-compose ps
63
+
64
+# View all logs
65
+docker-compose logs -f

159
+## 🤖 Local LLM Setup with Ollama
160
+
161
+### Step 1: Start Ollama Container
162
+
163
+```bash
164
+docker-compose --profile local-llm up -d ollama
165
+```
166
+
167
+### Step 2: Pull Grammar-Focused Models
168
+
169
+```bash
170
+# Enter Ollama container
171
+docker exec -it opengrammar-ollama bash
172
+
173
+# Pull models (inside container)
174
+ollama pull qwen2.5:0.5b # Ultra fast, 400MB
175
+ollama pull qwen2.5:1.5b # Balanced, 1GB
176
+ollama pull phi4-mini:3.8b # Great quality, 2.5GB
177
+ollama pull llama3.2:3b # Good all-rounder, 2GB
178
+
179
+# Exit container
180
+exit
181
+```
182
+
183
+### Step 3: Test Ollama
184
+
185
+```bash
186
+# Test from host
187
+curl http://localhost:11434/api/tags
188
+
189
+# Test model
190
+curl http://localhost:11434/api/generate -d '{
191
+ "model": "qwen2.5:1.5b",
192
+ "prompt": "Fix this grammar: me and him went to store"
193
+}'
194
+```
195
+
196
+### Step 4: Configure OpenGrammar
197
+
198
+1. Click extension icon → Settings
199
+2. Provider: **Ollama (Local)**
200
+3. Base URL: `http://localhost:11434/v1`
201
+4. Model: `qwen2.5:1.5b`
202
+5. API Key: (leave empty)
203
+6. Backend URL: `http://localhost:8787`

+## 🎯 Model Recommendations
208
+
209
+### For Grammar Checking
210
+
211
+| Model | Size | RAM | Speed | Quality | Best For |
212
+|-------|------|-----|-------|---------|----------|
213
+| **qwen2.5:0.5b** | 400MB | 1GB | ⚡⚡⚡⚡⚡ | ⭐⭐⭐ | Fast basic checks |
214
+| **qwen2.5:1.5b** | 1GB | 2GB | ⚡⚡⚡⚡ | ⭐⭐⭐⭐ | Balanced |
215
+| **phi4-mini:3.8b** | 2.5GB | 4GB | ⚡⚡⚡ | ⭐⭐⭐⭐⭐ | Best quality |
216
+| **llama3.2:3b** | 2GB | 3GB | ⚡⚡⚡⚡ | ⭐⭐⭐⭐ | Good balance |
217
+
218
+### For GPU Acceleration
219
+
220
+If you have an NVIDIA GPU:
221
+
222
+```bash
223
+# High quality with GPU
224
+ollama pull llama3.2:7b # 4GB, requires 8GB+ GPU
225
+ollama pull mistral:7b # 4GB, requires 8GB+ GPU
226
+ollama pull mixtral:8x7b # 26GB, requires 24GB+ GPU
227
+```
228
+
229

+
231
+## 🔧 Advanced Configuration
232
+
233
+### Custom Backend Port
234
+
235
+```yaml
236
+# docker-compose.yml
237
+ports:
238
+ - "9000:8787" # Change 8787 to 9000
239
+```
240
+
241
+### Enable GPU Support
242
+
243
+```yaml
244
+# For NVIDIA GPUs

297
+## 🛡️ Security Considerations
298
+
299
+### 1. Network Isolation
300
+```yaml
301
+networks:
302
+ opengrammar-network:
303
+ internal: true # No external access
304
+```
305
+
306
+### 2. Environment Variables
307
+Never commit `.env` file:
308
+```bash
309
+echo ".env" >> .gitignore
310
+```
311
+
312
+### 3. API Key Rotation
313
+```bash
314
+# Generate new keys periodically
315
+openssl rand -hex 32
316
+```
317
+
318
+### 4. Container Security
319
+```yaml
320
+security_opt:
321
+ - no-new-privileges:true
322
+read_only: true
323
+tmpfs:
324
+ - /tmp
325
+```
326
+

346
+curl http://localhost:8787/health
347
+
348
+# Ollama status

350
+
351
+# Container status
352
+docker-compose ps
353
+```
354
+
355
+### Update Containers
356
+```bash
357
+# Pull latest images
358
+docker-compose pull
359
+
360
+# Recreate containers
361
+docker-compose up -d --force-recreate
362
+
363
+# Clean up old images
364
+docker image prune -f
365
+```
366
+
367
+### Backup Data
368
+```bash
369
+# Backup Ollama models
370
+docker run --rm \
371
+ -v opengrammar_ollama_data:/data \
372

382
+## 🔄 Troubleshooting
383
+
384
+### Container Won't Start
385
+```bash
