# Nea Coder Pack > Mapping extensions to 1.8.9 MCP Currently, requires zwirn installed in the local maven repo: ```sh git clone https://github.com/nea89o/zwirn cd zwirn ./gradlew publishToMavenLocal ``` ## Editing workflow - `./gradlew unpackMappings` - `./gradlew launchEnigma` - `./gradlew generateDiffTiny` - `./gradlew generateMappingPatches` Usage in other projects is not possible right now, but a gradle plugin will eventually follow.
