 Pinhead uses a flavor of semantic versioning, with major releases (v2.0.0) corresponding to breaking changes, minor releases (v2.1.0) corresponding to backwards-compatible changes, and patch releases (v2.1.1) corresponding to fixes.
 
-When it comes to icons, renaming or deleting an icon, or making any visual modification, is a breaking change. Perhaps counterintuitively, we also consider the addition of any new icon to be a breaking change. The goal is clear version integrity, where each major version number refers to a complete set of icons with no differences between minor versions. This avoids common gotchas, like developers depending on a package like `^1.0.0` and potentially seeing different lists of icons in development vs. production in the case where v1.1.0 adds an icon.

 Contributions to Pinhead are **open**. I'd love to make this the best and largest library of public domain map icons anywhere on the web, but I can't do it alone. If you have questions, comments, or art, by all means open an [issue](https://github.com/waysidemapping/pinhead/issues/new) or [pull request](https://github.com/waysidemapping/pinhead/pulls/new) :)
 
+### Contributor FAQ 
+
+#### Is my icon in scope?
+
+Probably! While this project is focused on maps, you'd be surprised how many icons that don't seem geographic at all end up making useful pinheads.
+
+#### Why 15x15 pixels?
+
+The 15x15 rule mostly comes from Temaki, which inherited it from Maki. Compared to OSM Carto's 14x14, it's pretty handy to use an odd number so that a 1px wide line can be perfectly centered. Going down to 13x13 is feasible for the some icons but starts to get hairy when trying to depcit more complex things. Maki actually used to distribute 11x11 versions of icons (sooo tiny!) but [dropped them](https://github.com/mapbox/maki/commit/96e8b4c5941d687ddf0fde527ad54dde5559eef2) in v7. Probably the benefit didn't justify the maintence overhead in the age of high-DPI displays. So yeah, 15x15 just feels like the sweet spot.

 ### Design guidelines
 
 If the following sections seem too technical or intimidating, feel free to just ignore them and go straight to opening a PR for your cool icon. These are intended only for managing internal consistency and I'd be happy to give you pointers after the fact. There aren't many hard rules here. Have fun with it!

 ### AI/ML policy
 
 Icons generated by AI/ML models are assumed to be protected by copyright unless the model owner releases the rights to said icons AND said models have been trained exclusively on public domain sources or sources owned by the model owner. As this is generally never the case, and since major AI/ML model owners are known to be disingenuous about this stuff to the detriment of artists, AI-generated icons will not be considered for inclusion in Pinhead at this time.
 
 Since this repository is licensed in the public domain, you are technically free to train AI/ML models on the icons. But come on, wouldn't you rather draw a <img src="https://pinhead.ink/v1/bison.svg" height="15px" width="15px"/> lil guy and feel a little joy for once?
