 # etlp-mapper
 
-FIXME: description
+Etlp-mapper is a microservice that allows users to create jute based low code data transformation logic.
+This service can be used as a standalone Jute based data transformation utility, however, this service forms a crucial component of the `etl` based smart data connectors.

+### Production Build
+
+As a precursor you would need Leiningen, Clojure and Java installed on our machine, once we have the basic runtime up an running, we need to clone this repo and build an uberjar.
+
+
+```sh
+$ lein deps
+$ lein uberjar
+
+```
+
+#### Run Migrations 
+
+This service depends on Postgres >= v14.00, after successful java jar build, we need to run the migrations to create basic set of tables for our microservice. Once the migrations are successfully applied, we can simply run our jar and it should start the web server at `localhost:3000`

+```sh
+
+$  java -jar target/etlp-mapper-0.1.0-SNAPSHOT-standalone.jar :duct/migrator
+
+$  java -jar target/etlp-mapper-0.1.0-SNAPSHOT-standalone.jar
