+
+## Development
+
+DFPC provided Lambda ETLs are currently all written in [NodeJS](https://nodejs.org/en) through the use of a AWS Lambda optimized
+Docker container. Documentation for the Dockerfile can be found in the [AWS Help Center](https://docs.aws.amazon.com/lambda/latest/dg/images-create.html)
+
+```sh
+npm install
+```
+
+Add a .env file in the root directory that gives the ETL script the necessary variables to communicate with a local ETL server.
+When the ETL is deployed the `ETL_API` and `ETL_LAYER` variables will be provided by the Lambda Environment
+
+```json
+{
+    "ETL_API": "http://localhost:5001",
+    "ETL_LAYER": "19"
+}
+```
+
+To run the task, ensure the local [CloudTAK](https://github.com/dfpc-coe/CloudTAK/) server is running and then run with typescript runtime
+or build to JS and run natively with node
+
+```
+ts-node task.ts
+```
+
+```
+npm run build
+cp .env dist/
+node dist/task.js
+```
+
+### Deployment
+
+Deployment into the CloudTAK environment for configuration is done via automatic releases to the DFPC AWS environment.
+
+Github actions will build and push docker releases on every version tag which can then be automatically configured via the
+CloudTAK API.
+
+Non-DFPC users will need to setup their own docker => ECS build system via something like Github Actions or AWS Codebuild.
