+# Docker Services Guide
+
+This repository contains multiple microservices that can be run using Docker Compose.
+
+## Quick Start (With Cache)
+For regular development when dependencies haven't changed:
+```bash
+# Build and run Auth Service
+docker compose -f docker-compose-services.yml up auth-service
+
+# Build and run Event Service
+docker compose -f docker-compose-services.yml up event-service
+
+# Build and run Validation Service
+docker compose -f docker-compose-services.yml up validation-service
+
+# Build and run all services
+docker compose -f docker-compose-services.yml up
+```
+
+## Clean Build (No Cache)
+Use these commands when changing Dockerfile or dependencies:
+```bash
+# Auth Service
+docker compose -f docker-compose-services.yml build --no-cache auth-service && docker compose -f docker-compose-services.yml up auth-service
+
+# Event Service
+docker compose -f docker-compose-services.yml build --no-cache event-service && docker compose -f docker-compose-services.yml up event-service
+
+# Validation Service
+docker compose -f docker-compose-services.yml build --no-cache validation-service && docker compose -f docker-compose-services.yml up validation-service
+
+# All Services
+docker compose -f docker-compose-services.yml build --no-cache && docker compose -f docker-compose-services.yml up
+```
+
+## Service Ports
+- Auth Service: http://localhost:41575
+- Event Service: http://localhost:41576
+- Validation Service: http://localhost:41577
+
+## Development Notes
+- Use clean build (--no-cache) when:
+  - Changing Dockerfile
+  - Updating dependencies
+  - Experiencing caching issues
+- Use regular build (with cache) when:
+  - Only changing application code
+  - For faster development iterations
+- Run in detached mode:
+  ```bash
+  docker compose -f docker-compose-services.yml up -d auth-service
+  ```
+- Stop services:
+  ```bash
+  docker compose -f docker-compose-services.yml down
+  ```
