+# Nodarium Architecture
+
+The basic idea of nodarium is to use the advantages of WebAssembly to create a performant, secure and extandable visual programming language.
+
+## What is a node?
+
+```typescript
+type Node = {
+  id: string,
+  outputs: string[],
+  inputs: {
+    [key:string]: NodeInput
+  }
+}
+```
+
+## How are the nodes executed?
+
+## How are the nodes stored?
