+## Building
+Make you to have [wut](https://github.com/devkitPro/wut/) installed and use the following command for build:
+```
+make install
+```
+
+## Use this lib in Dockerfiles.

+Replace [tag] with a tag you want to use, a list of tags can be found [here](https://hub.docker.com/r/wiiuenv/libromfs_wiiu/tags).
+It's highly recommended to pin the version to the **latest date** instead of using `latest`.
