+# Waku v1 example
+## Introduction
+This is a basic Waku v1 example to show the Waku v1 API usage.
+
+It can be run as a single node, in which case it will just post and receive its
+own messages.
+
+Or multiple nodes can be started and can connect to each other, so that
+messages can be passed around.
+
+## How to build
+```sh
+make example1
+```
+
+## How to run
+### Single node
+```sh
+# Lauch example node
+./build/example
+```
+
+Messages will be posted and received.
+
+### Multiple nodes
+
+```sh
+# Launch first example node
+./build/example
+```
+
+Now look for an `INFO` log containing the enode address, e.g.:
+`enode://26..5b@0.0.0.0:30303` (but with full address)
+
+Copy the full enode string of the first node and start the second
+node with that enode string as staticnode config option:
+```sh
+# Launch second example node, providing the enode address of the first node
+./build/example --staticnode:enode://26..5b@0.0.0.0:30303 --ports-shift:1
+```
+
+Now both nodes will receive also messages from each other.
