+
+## POST /v1/generate
+Returns a zip file containing the generated mod template zip
+
+### Request:
+
+```json
+{
+    "minecraftVersion": "1.20.4", // Optional, defaults to the latest stable version
+    "modName": "Example Mod", // Optional, defaults to "Example Mod"
+    "modId": "example_mod", // Optional, defaults to being generated from the mod name
+    "packageName": "com.example", // Optional, defaults to being generated from the mod id
+    "options": { // Optional
+        "kotlin": false, // All sub keys are optional
+        "dataGeneration": false,
+        "splitSources": true
+    }
+}
+```
+
+### Response (200):

+### Response (400):
+
+An human reasonable error message, e.g "Invalid package name"

+    "field": "packageName" // An optional field to indicate what input was incorrect.
