-## Getting Started
+## Get Started
 
-```console
+Prerequisites:
+- Node & Npm
+- Docker & Docker Compose
+
+```bash
+<node-version-manager> use
+npm install
 docker compose up -d
-docker compose run --rm app pip install -r requirements.txt
-docker compose run --rm app python index.py
+```
+
+## Serverless
+
+```bash
+serverless invoke local --function synchronize-geozones
+serverless invoke local --function synchronize-decrees
+serverless invoke local --function synchronize-restrictions -p events/restriction-query.json
+```
+
+```bash
+serverless deploy --stage staging
+serverless deploy --stage prod
+```
+
+## SQL Commands
+
+Get center point long lat of the first geozone:
+```sql
+SELECT gz.id, gz.name, ST_X(ST_Centroid(gz.geometry)) as longitude, ST_Y(ST_Centroid(gz.geometry)) as latitude, de.alert_level. re.user_individual
+FROM geozone AS gz
+INNER JOIN decree AS de ON de.geozone_id = gz.id
+INNER JOIN restriction AS re ON re.decree_id = de.id
+WHERE de.start_date <= NOW() AND de.end_date >= NOW()
+LIMIT 1;
+```
+
+Find geozones by lat long:
+```sql
+SELECT gz.id, gz.external_id, gz.type, gz.name, de.alert_level
+FROM geozone AS gz
+INNER JOIN decree AS de ON de.geozone_id = gz.id
+WHERE ST_Contains(
+    gz.geometry,
+    ST_SetSRID(
+        ST_MakePoint(4.356850234425376, 49.4610139711892),
+        4326
