+Maintenance!
+
+
+## The Ziglings Audience
+
+Ziglings is is intended for programmers of all experience levels. No specific
+language knowledge is expected.  If you can install the current Zig snapshot,
+setup a copy of Ziglings, and understand if/then/else, loops, and functions,
+then you're ready.
+
+Experience with strong typing, manual memory management, and certain language
+constructs and idioms will greatly increase the speed at which you'll be able
+to tackle each exercise. But speed isn't important, only learning is important.
+
+Ziglings is intended to be completely self-contained. If you can't solve an
+exercise from the information you've gleaned so far from Ziglings, then the
+exercise probably needs some additional work. Please file an issue!
+
+If an example doesn't match a description or if something is unclear, please
+file an issue!
+
+
+## Spelling/Grammar
+
+If you see any typos, please file an issue or make a pull request.
+
+No mistake is too small. The Ziglings must be perfect.
+
+
+## Ideas
+
+If you have ideas for new lessons or a way Ziglings could be improved, don't
+hesitate to file an issue.
+
+I prefer to actually write all of the content myself at this time (part of the
+reason I'm building Ziglings is to learn Zig myself!), but I'm always open to
+ideas.
+
+
+## Platforms and Zig Versions
+
+Because it uses the Zig build system, Ziglings should work wherever Zig does.
+
+Since Ziglings is a Zig language learning resource, it tracks the current
+development of Zig.
+
+If you run into an error in Ziglings due to language changes (and you have the
+latest development build of Zig and the latest commit to Ziglings), that's a
+bug! Please file an issue.
+
+
+## Formatting
+
+All exercises are (or should be) formatted with `zig fmt`.
+
+
+## Pull Request Workflow
+
+Ziglings uses the "standard" Github workflow as guided by the Web interface.
+Specifically:
+
+* Fork this repository
+* Create a branch from `main` for your work: `git checkout -b my-branch`
+* Make changes, commit them
+* When your changes are ready for review, push your branch: `git push origin
+  my-branch`
+* Create a pull request from your branch to `ziglings/main`
+* Your faithful Ziglings maintainer "ratfactor" (that's me!) will take a look
+  at your request ASAP
+* Once the changes are reviewed, your request will be merged and eternal
+  Ziglings contributor glory is yours!
+
