+# Downloading and Launching sensiNact
+
+This worked example aims to get you started with running sensiNact for the first time.
+
+## Downloading sensiNact
+
+Eclipse sensiNact is published to the Eclipse Nexus repository instance at [https://repo.eclipse.org](https://repo.eclipse.org). You can find it directly there, or use the maven-dependency plugin to find it for you.
+
+    mvn dependency:get -DremoteRepositories=https://repo.eclipse.org/content/groups/sensinact/ \
+    -Dartifact=org.eclipse.sensinact.gateway.distribution:assembly:0.0.2-SNAPSHOT:zip -Ddest=sensinact.zip
+
+## Installing sensiNact
+
+Once you have obtained the sensiNact assembly you can unzip it using your favourite zip tool
+
+     unzip sensinact.zip
+
+The unzipped contents will include several folders and files including:
+
+* `configuration` - the folder containing the configuration for the gateway instance
+* `features` - the folder containing the available features that can be installed into this gateway
+* `launch` - the folder containing the sensiNact launcher responsible for bootstrapping the gateway
+* `repository` - a maven layout repository containing the bundles used by the gateway features
+* `start.sh` - a launch script for sensiNact
+
+## Starting sensiNact
+
+Starting sensiNact can be achieved simply by executing the start script
+
+    ./start.sh
+
+> [!WARNING]
+> If you are unable to execute the start script try setting the executable permission bit using `chmod +x start.sh`
