 # GrowGuides
 
-Scientifically grounded, beginner-accessible grow guides for a variety of fungi species.
+A collection of open-source cultivation science guides for gourmet and medicinal mushrooms — written to be scientifically honest, beginner-accessible, and freely shared.
+
+Each guide covers the biology, ecology, colonization, fruiting, and harvest of its species in depth. The goal is that you understand not just *what to do*, but *why every parameter matters* — because cultivation is not a checklist. It is an act of biological collaboration.

+## License
+
+These guides are published under the **MIT License**.
+
+In plain terms: **do whatever you want with them**. Print them. Share them. Adapt them for your grow operation, your classroom, your community garden, your mushroom club, your zine, your farm stand handout. Translate them. Build on them. Sell a printed copy at your farmers market if you like.
+
+The only thing we ask — and the only requirement of the MIT License — is that **you include the license text and attribution** when you distribute them or any derivative. That means keeping the `LICENSE` file alongside the guides, or printing the license text with any physical copies you make. That's it.
+
+You do not need to ask permission. You do not need to notify anyone. You just need to keep the license attached.
+
+The spirit behind this: cultivation knowledge has historically been gatekept by geography, cost, and access. Good science shouldn't be. These guides exist to be used.
