 ## Usage
 
+You need to host a local http server for providing the definition files. Please create a dedicated directory @ `localhost` for that purpose.
+### Prerequisites
+
 First, you need to generate the visualisation data:
 
 ```
-cabal run workflow-visualiser -- <source.yaml> <target.json>
+cabal run workflow-visualiser -- --all <path-to-source-yaml-directory> <directory-of-http-server>
 ```
 
-Copy the contents of `target.json` and paste them as the value of the variable `workflow` into the first line of [`editor.js`](./editor.js#L1).
-
-Open `editor.html` in order to display the graph.

+Afterwards you can run your server and listen on port `8080`.
+### Open Editor
+Open `editor.html` in your browser and select the desired workflow via the file menu.
