 - Run `kubectl config use-context dallas-rke`
 - First, startup the storage (using internal qa for example)

-- Then, startup the database (give it 60 seconds)

+# Serval API Example
+
+This example application will generate a pre-translation USFM draft using the Serval API, and display it in the terminal window.
+
+## Pre-Requisites
+
+ * .NET SDK 8.0
+ * You must have a Serval Client ID and Client Secret before running this example.
+
+## Setup
+
+Before running, you must configure your Serval Client Id and Client Secret via `dotnet user-secrets`:
+```
+dotnet user-secrets set "Serval:ClientId" "your_client_id_here"
+dotnet user-secrets set "Serval:ClientSecret" "your_client_secret_here"
+```
+
+## Run
+
+To run this example after configuring your user secrets, execute the following command from a terminal window:
+
+```
+dotnet run
+```

+\mt1 Epistle to the Laodiceans
+\imt Introduction
+\ip The following is a translation of the J.B. Lightfoot’s reverse translation of the surviving Latin translation of the Epistle to the Laodiceans into Koine Greek. This translation, published in his commentary on Colossians and Philemon (new edition, 1879) is based on the premise that the original epistle is a composition of quotations from the Pauline Epistles, compiled by an unknown author, purporting to be a letter from Paul to the church at Laodicea.
