+jsii configuration is read from the `jsii` section in the module's
+`package.json` and includes the following options:
 
  * `targets` - the list of target languages this module will be packaged for. For each
    target, you would need to specify some naming information such as namespaces, package manager
    coordinates, etc. See [supported targets](#targets) for details.
  * `outdir` - the default output directory (relative to package root) for
-   __jsii-pacmak__. This is where target artifacts are emitted during packaging. Each artifact
-   will be emitted under `<outdir>/<target>` (e.g. `dist/java`, `dist/js`, etc).

- * `js` - implicit - every module will always have a "js" target (dah!).
- * `java` - packages the module as in Java/Maven package. Requires the following config:
+The `$outdir/java` directory will include the contents of a staged offline Maven
+repository. javadocs and sources are included automatically in the Maven package
+
+This repository can be published to [Maven Central](https://search.maven.org/)

+[`mdinclude`](https://miyakogi.github.io/m2r/example.html#include-markdown-file)

+
+NOTE: if the first line of your `README.md` file starts with `# ` (an H1
+header), the contents of this line will be used as the first header of the

+You will need to build a Sphinx documentation website with this `.rst` included.

+To package your jsii module as a Sphinx topic, add an empty object to the
+`jsii` section in `package.json` under the `sphinx` key:
