+# Docker Configuration Guide
+
+The application can be run with different configurations using Docker Compose:
+
+- `docker-compose.yml`: Core application
+- `docker/ollama/compose.yml`: Ollama service for local LLM inference
+- `docker/argilla/compose.yml`: Argilla service for data curation
+
+## Ollama Integration
+
+The `MODEL` variable in your `.env` file determines which model Ollama will download and use. For example:
+```env
+MODEL=llama3.2:1b
+```
+
+- Ollama will automatically download and set up the specified model
+- No manual commands or downloads are needed
+
+
+## Setup Options
+
+### Full Setup (App + Ollama + Argilla)
+```bash
+# Keep all sections uncommented in .env
+docker compose -f docker-compose.yml -f docker/ollama/compose.yml -f docker/argilla/compose.yml build
+docker compose -f docker-compose.yml -f docker/ollama/compose.yml -f docker/argilla/compose.yml up -d
+```
+
+### App + Ollama
+```bash
+# Comment out ARGILLA section in .env
+docker compose -f docker-compose.yml -f docker/ollama/compose.yml build
+docker compose -f docker-compose.yml -f docker/ollama/compose.yml up -d
+```
+
+### App + Argilla
+```bash
+# Comment out OLLAMA section in .env
+docker compose -f docker-compose.yml -f docker/argilla/compose.yml build
+docker compose -f docker-compose.yml -f docker/argilla/compose.yml up -d
+```
+
+### App Only
+```bash
+# Comment out both OLLAMA and ARGILLA sections in .env
+docker compose -f docker-compose.yml build
+docker compose -f docker-compose.yml up -d
+```
+
+## Managing Services
+
+Services are built separately but are linked together. If you already have some services built and want to add another:
+
+1. You don't need to rebuild existing services
+2. Just build the new service
+3. Stop everything with `down` and start again with `up`
+
+For example, if you have App + Ollama and want to add Argilla:
+```bash
+docker compose -f docker/argilla/compose.yml build  # only build Argilla
+docker compose -f docker-compose.yml -f docker/ollama/compose.yml -f docker/argilla/compose.yml down
+docker compose -f docker-compose.yml -f docker/ollama/compose.yml -f docker/argilla/compose.yml up -d
+```
+
+Similarly, if you have built all services but want to run only some of them:
+> **Important**: When running specific services, remember to comment out unused services in `.env` first
+
+```bash
+# No need to build again, just start the services you need
+docker compose -f docker-compose.yml -f docker/ollama/compose.yml up -d  # start only App + Ollama
+```
+
+## Service URLs
+
+Once running, access the services at:
+- App: http://localhost:7860
+- Argilla: http://localhost:6900 (if enabled)
+- Ollama: http://localhost:11434 (if enabled)
+
+> Note:  Services will be available after a few seconds while they initialize. Ollama models and Argilla datasets are persisted and available after restarts
