Step-by-step: How to create, publish and distribute an extension ?

Scan through the user and developer extension FAQs
(Optionally) Present your extension(s) on the slicer developers list to check if other developer are working on a similar project, to seek for advice or to reach out for potential collaborator.
Build Slicer application in Release
Use the Wizard to easily create an extension containing one or more Slicer modules.
Create a repository to save your work. We recommend GitHub
Implement your extension. Hack, hack, hack :) and commit often.
Create a documentation page for your extension.
If not already done, send an email on the slicer developers list asking to be granted write permission on the experimental folder.
Create an account on the extension server and obtain an API Key. You can then used your midas login and api key to substitute <YOUR-MIDAS-LOGIN> and <YOUR-MIDAS-APIKEY> in the examples.

Assuming the source code of your extension is located in folder MyExtension, you could upload your extension doing:

Makefile	Visual Studio
$ mkdir MyExtension-build $ cd MyExtension-build $ cmake -DCMAKE_BUILD_TYPE:STRING=Release -DMIDAS_PACKAGE_EMAIL:STRING=<YOUR-MIDAS-LOGIN> -DMIDAS_PACKAGE_API_KEY:STRING=<YOUR-MIDAS-APIKEY> -DSlicer_DIR:PATH=/path/to/Slicer-Superbuild/Slicer-build ../MyExtension $ make ExperimentalUpload	Start CMake, select source and build directory Add `Slicer_DIR`, `MIDAS_PACKAGE_EMAIL` and `MIDAS_PACKAGE_API_KEY` entries to the cache Click on Configure, then Generate button. Open `MyExtension.sln` (1), select `Release` (2), select `ExperimentalUpload` (3) and build (4).

Check submission results on the dashboard: http://slicer.cdash.org/index.php?project=Slicer4#Extensions-Experimental
Check that the extension can be installed using the extensions manager.
If you consider your extension ready for distribution, follow these instructions. to contribute the already generated description file.
