Hi here! I’m happy to announce that the Pebble documentation website is live now!
If you are not familiar with Pebble yet, now it’s a good time to check it out 
In short, it’s a lightweight process manager used through ops (ops.pebble.Client) to give workload containers something like an init system, allowing the charm container to interact with them. Read more on the official documentation website and Juju SDK docs.
We’ve done a few iterations, and now we have some basic content to start with. It’s still a work in progress, not fully finished yet; consider it a “beta” version. Any feedback is welcome!
We plan to add more how-to guides and API docs in the future. Stay tuned! Thanks!
