+Dreamlab scripts are written in TypeScript and all new projects are created from one of our pre-made templates.

 ## Entrypoints
 
-{/* TODO: entrypoints info */}
+All scripts must implement three entrypoints for client code, server code, and level data. These are `client.ts`, `server.ts`, and `level.ts` respectively.
+Client and Server entrypoints must export a single function named `init()` that has a single argument, a reference to the current Dreamlab game context.
+
+Although not strictly required, we recommend defining another shared entrypoint that is called by both client and server `init()` functions that calls
+any common code shared between client and server. A good example of such code would be [registering spawnable entities](./entities.mdx#registering).
+
+<Callout>
+ All new projects created from our templates already have these entrypoints set
+ up correctly and are fully typed.
