 # FlowOps
-Automated, repeatable tasks for NiFi data flow operations.
 
+Automated, repeatable tasks for [Apache NiFi](https://nifi.apache.org) data flow operations.
+
+## Quickstart Guide
+
+### FlowOps Docker Image
+
+The FlowOps Docker image comes with useful tools for automating Apache NiFi data flow operations, such as the [Apache NiFi Toolkit CLI](https://github.com/apache/nifi/tree/master/nifi-toolkit/nifi-toolkit-cli) and [NiPyAPI](https://github.com/Chaffelson/nipyapi)
+
+Pull from Dockerhub:
+
+    docker pull kevdoran/flowops:latest
+
+Run interactively:
+
+    docker run -it kevdoran/flowops:latest
+
+This will drop you into a bash shell on a flowops container. Most of the commands you need to get started are already on the path (e.g., the NiFi Toolkit /bin directory). Also, there are a number of [scripts](#scripts) located in `/scripts` that you may find useful. 
+
+If you want to use the FlowOps image to control NiFi or Registry containers running in an existing environment (e.g., one created by docker-compose), just specify the network those containers are bound too:
+
+    docker run -it --network <docker-network-name> flowops:latest
+
+Lastly, FlowOps is designed to be included as part of a docker-compose configuration. For an example, see the NiFi & NiFi Registry [docker-compose.yml](https://github.com/kevdoran/flowops/blob/master/docker/demo/nifi-registry/docker-compose.yml) demo.
+
+## Scripts
+
+The FlowOps Docker image comes with a number of scripts to facilitate common actions. These are located in the `/scripts` directory in the flowops image.
+
+TODO, provide documentation for provided / built-in scripts.
+
+## Demos
+
+### Apache NiFi & NiFi Registry
+
+This demo starts the FlowOps demo that connects Apache NiFi and NiFi Registry containers in a docker-compose environment. See the [docker-compose.yml](https://github.com/kevdoran/flowops/blob/master/docker/demo/nifi-registry/docker-compose.yml) file in this repo for details.
+
+#### From master branch
+
+    wget -qO- https://raw.githubusercontent.com/kevdoran/flowops/master/docker/demo/nifi-registry/docker-compose.yml | docker-compose -f - up
+
+#### From a stable release
+
+    FO_VERSION=0.1.0 \
+    && wget https://github.com/kevdoran/flowops/archive/v${FO_VERSION}.tar.gz \
+    && tar -xzf flowops-v${FO_VERSION}.tar.gz \
+    && cd flowops-v0.1.0/docker/demo/nifi-registry \
+    && docker-compose up
+
+In the above example, replace FO_VERSION=0.1.0 with the version you wish to use. Releases can be found at the [releases page](https://github.com/kevdoran/flowops/releases).
