 ## Build instructions
 
-1. This docker file assumes the Vivado download is available on a webserver somewhere. This can easily be the build machine using the webserver in Python.
-    ```shell
-    cd /path/to/Vivado/download
-    python -m http.server
-    ```
-2. Copy your Vivado `Xilinx.lic` file into the directory.
+1. Copy the Vivado installation package `Xilinx_Vivado_SDK_2018.1_0405_1.tar.gz` to this folder.
 3. Potentialy modify the `install_config.txt` to change the install options.

     ```
 
 ## Running
 
-The `Dockerfile` sets up a `vivado` user to avoid running as root. I have only considered running Vivado in `batch` mode for running CI simulations and building bit files. For development work with the GUI you may have to fiddle with X11 settings.
+    ```shell
+    docker run -ti --rm -e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix vivado:2018.1
+    ```
