+This folder contains all files relevant to a specific WissKI Distillery instance.
+This documentation provides basic information about all files and may be updated in future changes.
+
+## Container Files
+
+These are required for the container to function properly.
+DO NOT EDIT THESE, changes will be overwritten during the next rebuild.
+
+- `docker-compose.yml`: Defines how the docker image is run
+- `Dockerfile`: Dockerfile used to run the actual image
+- `.env`: Parameters for `docker-compose.yml`
+- `apache.d`, `scripts`, `php.ini.d`: Resources used during the docker-compose build.
+
+To tweak parameters inside the `.env` file, rebuild the image via `wdcli rebuild`.
+
+## Data Files
+
+These contain user data and settings for the instance.
+You can edit these (changes will __not__ be overwritten).
+Editing these may still risk breaking your instance; do so at your own risk.
+
+- `data`: Drupal Installation and user home directory
+- `ssh`: SSH Host keys; modify at your own risk
+- `settings.local.php`: settings.php added to this distillery instance
+- `prefixes.skip`: If this file exists, prefixes from this wisski instance will not be added to the global resolver.
