+# Gno Live Coding Session #3
+
+#### Topic: Creating your own GRC20 token while Gno language features 
+#### Date: Friday, Sept 13th 2024
+#### Presenter: [@leohhhn](https://github.com/leohhhn)
+
+This Live Coding session creating a [`GRC20`](https://gno.land/p/demo/grc/grc20) token
+in Gno, while exploring Gno's language features, such as calling methods on 
+exported top-level variables.
+
+The code contains an example of a GRC20 token, example 
+[`Run`](https://docs.gno.land/gno-tooling/cli/gnokey/state-changing-calls#run)
+scripts which enable interactions with it. 
+
+## Following up
+
+We encourage anyone who wishes to build upon the example given in the coding
+session to do so. Please make a PR adding your code to the 
+[`followup-work/`](./followup-work) folder, and ping the presenter.

+// Package run20 showcases a simple way to create a GRC20 token using the p/demo/grc/grc20 package.
+// This package also showcases how to use the MsgRun message type:
+// Exposing a variable of a type that contains exposed methods will expose those methods to the end-user as well.
+// In this example, it is the grc20.Token interface type.
+// Currently, the only way to interact with it is via MsgRun (https://docs.gno.land/gno-tooling/cli/gnokey/state-changing-calls#the-power-of-run)
+// The `example_interactions` folder contains Gno scripts that can be provided to the Run transactions to execute these methods.
+// This functionality is planned for MsgCall as well in the future.
+// For more token examples, check out wugnot, foo20, and bar20 in the examples/ folder in the Gno monorepo.
