If the apps is listed in the second column, you can easily install it from the store by just running: sudo snap install <snap name>.

Why?

As snapd and its underlying technologies are new and we want to figure the best use of it together, we want to create a space, where we collectively

• collaborate on creating snaps
• demonstrate best-practices
• provide an incubator for new projects to be snapped

This is the snappy playpen.

How it all works

No matter if you

• are involved with an upstream project who wants to get their software snapped
• are somebody who is interested in providing a snap for an app
• are working on a device which needs its software snapped
• are somebody who's curious about technology
• think this is interesting

we want you to get involved.

Fixing issues

If you want to provide a fix for one of the apps in this repository, simply follow our contributor guidelines and file a pull request.

Adding new snaps

If you are working on a new, interesting snap and

• got it working: follow the guidelines and file a pull request
• need help to get it working: send a mail to the snapcraft mailing list, introduce the project and push up a branch of your playpen fork to github, so others can take a look and help out

Events

Over time we want to have "sprints", in which we focus on a certain piece of software, or where we invite interested upstream developers. We are going to announce these on the snapcraft mailing list.

Snapping your software

The best place to get started with snapd and snapcraft is on the http://snapcraft.io. Check out the examples, and simply by running snapcraft init you should be on the way to creating your first snap.

In the beginning it is a good idea to use

confinement: devmode

in your snapcraft.yaml declaration. It will relax the security requirements so you can get your snap fully working first and then look into the security bits next. Just set the confinement value to strict when you are done.

If you are collaborating with a team of developers on your snap, you might want to run your snap build using snapcraft cleanbuild once you're happy with everything. It will make sure that the build also passes in a clean container. This way you will avoid surprises about missing build-packages and other local modifications.

Once everything is fully working, consider asking the upstream project to add your snapcraft.yaml file to their repository. Publishing to the store is easy. Maybe they are going to be interested in knowing that that for every new release or milestone, a new snap in the store is only a matter of running snapcraft upload.

Getting in touch

If you have questions or want to get to know the people behind snapd and friends, there are many ways to get in touch:

• We are on gitter. Just hit us up there, it's easy.
• There is also the snapcraft mailing list.
• If you are on IRC, we are on #snappy irc channel on Freenode.
