+Contributing to Orion/LSP Support
+=================================
+
+Thanks for your interest in this project.
+
+Setup instructions
+------------------
+
+1) Clone the [orion.client](https://github.com/eclipse/orion.client) Git repository checkout the `java-lsp` branch.
+
+2) Get the lsp server from the [eclipse.jdt.ls](https://github.com/eclipse/eclipse.jdt.ls.git) Git repository and follow the `README.md` file to build it.
+dfd
+3) Install the compiled LSP server from the `org.eclipse.jdt.ls.product/target/repository` folder to the  `org.eclipse.orion.client/modules/orionode/server` folder.
+
+4) Inside a console where Node.js is installed, do:
+  - `npm install`
+  - start it by using: `node --debug server.js -p 8083 --w <workspace_path>`
+  This runs the Node.js Orion server on localhost:8083.
+
+5) Open the browser on `http://localhost:8083`.
+The Orion client with the Java™ plugin requires a Node.js Orion server that is enabled for the language server connections.
+This is why for now we use a local Node.js server instead of the instance running on [orion.eclipse.org](https://orion.eclipse.org).
+
+6) In order to help users to test the latest integration, we provide a Dockerfile and a shell script that can be used to build 
+a docker image that contains the latest version of the orion Node.js server with lsp support and the latest implementation of the
+Java lsp server provided by the eclipse.jst.ls project. In order to do so, you need to go to the `orion.client/modules/orionode/` folder.
+Then invoke the `./docker_build.sh` command. Once done, start your image using `docker run -p 8081:8081 orionlsp` and open your browser on at
+`http://localhost:8081/`. You will start with an empty workspace in which you can git clone a project with Java files and test the lsp support.
