 You should make sure that the following components are pre-installed on your machine:
 
-- [Node.js](https://nodejs.org/en/download/)
+- [docker](https://docs.docker.com/engine/install/)
 
 ## Using the webapp
 
-- Download the release from github
-- extract archive into folder
-- inside that folder create an assets folder where you put in the mp4- and vtt-files that you need to download from coursera
-  - the app expects to have _one_ mp4-file next to _one_ vtt-file in a subfolder.
-- run the command below to create a listing of the contents (since the webapp running in the browser cannot list all files in a directory)
-- you can now serve the folder as static files (e.g. `npx serve`)
+I created a docker image that hosts a static fileserver. This serves both the webapp and also the recordings on your machine. 
+To give the image access to your files, you need to mount the folder with your recordings to `/assets` inside the docker container.
+
+```shell
+docker run --rm \
+       -p 8080:8080 \
+       -v "/the/path/to/your/assets/:/assets/" \
+       --name subtitle-search \
+       ghcr.io/flowi/subtitle-search:latest
+
+```
+
+The only requirement is that your assets folder contains a subfolder for each lesson that contains both the mp4 and vtt files. 
+The naming and depth doesn't matter - the fileserver will walk the whole directory tree to look for mp4-vtt pairs. 
+
+### Example of a folder structure:
 
-This is how your folder should look like
 `tree -l .`
