+# Intro
+
+Akka is a toolkit and runtime for building highly concurrent, distributed, and resilient message-driven applications on the JVM.
+See http://akka.io
+
+
+To use Akka, you want to have two different machines:
+- One considered `remote` which stores the data
+- One considered `local` which is the public facing side of the API, where your users will connect
+
+Both run current versions of the Open Bank Project API, but configured and run differently.
+
+
+# Remote side
+
+- Configure `src/main/resources/default.props`: 
+
+```ini
+# Remote end gets data 'locally'
+remotedata.enable=false
+# Your remote's external IP address
+remotedata.hostname=10.0.0.19  
+# Arbitrary port of your choosing
+remotedata.port=5448
+
+# Optionally configure postgres, otherwise file-based H2 will be used 
+remotedata.db.driver=org.postgresql.Driver
+remotedata.db.url=jdbc:postgresql://localhost:5432/dbname?user=user&password=password
+```
+
+## Run
+
+```bash
+#!/bin/sh
+
+cd ${HOME}/OBP-API/ && /usr/bin/nohup /usr/bin/mvn compile exec:java -Dexec.mainClass="code.remotedata.RemotedataActors" -Dexec.args="standalone" > ${HOME}/akka_remote_api.log &
+```
+
+
+
+# Local OBP API side
+
+- Configure `src/main/resources/default.props`:
+
+```ini
+# Local end gets data remotely
+remotedata.enable=true
+# Your remote's public IP address
+remotedata.hostname=10.0.0.19
+# Arbitrary port of your choosing, has to match remote above
+remotedata.port=5448
+```
+
+# Run
+
+```bash
+#!/bin/sh
+
+cd ${HOME}/OBP-API/ && /usr/bin/nohup /usr/bin/mvn jetty:run -Djetty.port=8080 -DskipTests  > ${HOME}/akka_local_api.log &
+```
