+# Mithril client wasm library example: Node.js
+
+## Description
+
+This example shows how to implement a Mithril client and use its features in a Node.js environment.
+
+In this example, the client interacts by default with a real aggregator on the network `testing-sanchonet` to:
+
+- Mithril Stake Distribution:
+  - list the available Mithril Stake Distributions
+  - verify the latest Mithril Stake Distribution
+  - verify a certificate chain
+  - compute a message
+  - verify that the certificate signs the computed message
+- Cardano transactions
+  - get proof of inclusion for a known set of Cardano transactions
+  - verify a certificate chain
+  - compute a message for
+  - verify that the certificate signs the computed message
+
+## Build and run the example
+
+First you need to compile the Mithril client Wasm library:
+
+```bash
+make -C ../../mithril-client-wasm build
+```
+
+Then you can run the example:
+
+```bash
+npm install
+npm run start
+```
