-OSC will only work if you run the REPL locally + the OSC server besides it:
+Assuming you have [node.js](https://nodejs.org/) installed, you can run the osc bridge server via:
 
-From the project root:
-
-```js
-npm run repl
+```sh
+npx @strudel/osc
 ```
 
-and in a seperate shell:
-
-```js
-npm run osc

-Now open the REPL and type:
+By default it will use port 57120 for the osc client, which is what [superdirt](https://github.com/musikinformatik/SuperDirt) uses. You can change it via the `--port` option:
 
-```js
-s("<bd sd> hh").osc()

 ```
 
-or just [click here](https://strudel.cc/#cygiPGJkIHNkPiBoaCIpLm9zYygp)...
+### --debug
+
+To log all incoming osc messages, add the `--debug` flag:
+
+```sh
+npx @strudel/osc --debug

+
+## Usage in Strudel
+
+To test it in strudel, you have can use `all(osc)` to send all events through osc:
+
+```js
+$: s("bd*4")

+```
