+A tool to convert an [RDA](https://devforce.disa.mil/secure/docs/latest/developers-guide/deployment/) into one or more [Helm](https://helm.sh/) [Charts](https://helm.sh/docs/glossary/#chart) and container image files (i.e. Dockerfile).
 
-To update this image, first get the URL to the version of the rda-converter from [nexus](https://nexus.devforce.disa.mil/#browse/search/maven=attributes.maven2.groupId%3Dbdp.rda%20AND%20attributes.maven2.artifactId%3Drda-converter).
