Is this the main support channel?

There are a number of more narrowly-focused channels, e.g. azure, dotnet, aws, golang, etc. Those seem to be better places for specific questions.

This channel is mostly for folks who are getting started with Pulumi. The overall Slack is informal community support; for paid product support, there are other channels to utilize. Finally, as @little-library-54601 mentioned, there are more narrowly-scoped channels that might be more helpful depending on what you’re trying to accomplish. How can I help?
