### Submitting the Package
You should first fork the MELPA repository, add your new file under `recipes`, and confirm your new package builds properly by running `buildpkg <NAME>`. You can install the package that you built by running the interactive command `package-install-file` in Emacs, and specifying the newly built package which should be in the `packages/` subdirectory under the melpa directory.

After verifying the entry works properly please open a pull request on Github.
## Configuration
Packages end up in the `packages/` directory by default.
This can be configured using the `package-build-archive-dir` variable.
