+
+This repository contains Dockerfiles for setting up the Temporal.io Development Server in two variants:
+
+1. Generic: A flexible configuration suitable for general purposes.
+2. GitHub Actions: A specialized configuration with defaults set for use in GitHub Actions workflows,
+optimized for testing with a predefined namespace and only exposing port 7233.
+
+# Introduction
+
+Temporal.io is a microservices orchestration platform for running mission-critical code at any scale.
+This repository provides Dockerfiles for setting up a Temporal.io development server in two distinct configurations
+to aid in local development and continuous integration (CI) processes.
+
+# Running the Container
+
+Start the container using the appropriate variant:
+
+## Generic
+
+```shell
+docker run -p 7233:7233 -p 8233:8233 ghcr.io/infinityflowapp/temporal-dev-server:<version>
+```
+
+## GitHub Actions Service
+
+Add or update the services section of your workflow
+
+```yaml
+jobs:
+  <job>:
+    services:
+      <service>:
+        image: ghcr.io/infinityflowapp/temporal-gha-service:<version>
+        ports:
+          - 7233:7233
+```
+
+Use a client pointing to your service (pseudo code)
+
+```java
+var client = new TemporalClient("<service>:7233");
+```
