docs: clarify project status

Having read Hintjens’s Social Architecture book, I want to try to build
a community around selfoss, so that I am not the sole developer forever.

Until then, I need to document the current state so that people do not
expect more than I have the capacity to provide.

+If you discover a bug, please [report it to the issue tracker](https://github.com/fossar/selfoss/issues/new). Try to describe the problem in as much detail as possible.

+You can also ask for a new feature but unless I would personally use it, I will probably not find time to implement it.
 
 
 ## Contributing code
 
 We accept [pull requests](https://github.com/fossar/selfoss/compare) with your changes.
 
+For larger changes, please discuss it in an issue first, to avoid potentially wasting effort.
+
 Every patch is expected to adhere to our coding style, which is checked automatically by CI. You can install the checkers locally using `npm run install-dependencies`, and then run the checks using `npm run check` before submitting a pull request. There is also `npm run fix`, that will attempt to fix the formatting.
 
 Please try to make commits small and self-contained. If you need to tweak something you previously committed, squash the new changes into the original commit before the PR is merged. `git commit --fixup` and `git rebase --autosquash` will help you, see https://dev.to/koffeinfrei/the-git-fixup-workflow-386d.
