+- Configuration via .env file
+- Ready for use with traffic
+- Using github master for now, release 0.3.0 too old
+- Creating customize folder
+- Adding config.js to customize folder
+- Persistance for datastore and customize folder
+
+## TODO
+
+```
+cryptpad_1  | Linking config.js
+cryptpad_1  | Using secure websockets: true
+cryptpad_1  | Using storage adapter: './storage/file'
+cryptpad_1  | sed: -e expression #1, char 27: unknown option to `s'
+```
+
+## Configuration
+
+Set configurations Dockerfile or in .env (using docker-compose) file.
+
+- VERSION=latest
+- USE_SSL=false
+- STORAGE='./storage/file'
+- LOG_TO_STDOUT=true
+
+The .env variables are read by docker-compose and forwarded to docker container.
+On runtime, in `bin/container-start.sh` the settings are written to the `config.js` file.
+
+## Run
+
+With docker
+
+```
+docker build -t xwiki/cryptpad .
+docker -d --name cryptpad -p 3000:3000 -v ${PWD}/data:/cryptpad/datastore xwiki/cryptpad
+```
+
+With docker-compose
+
+```
+docker-compose up -d
+```
+
+
+## Persistance
+
+The docker-compose file is preconfigured to persist folders
+
+- cryptpad/datastore --> ./data/customize
+- cryptpad/customize --> ./data/customize
+
+In customize included find your configuration in `config.js`.
+
+The data folder is ignored by git, so if you want to add your customizations to git versioning change the volume:
+
+```
+./customize:/cryptpad/customize:rw
+```
+
+## SSL Proxy
+
+The [traefik](https://traefik.io/) proxy has builtin Let'sEncrypt for easy SSL setup.
+In the docker-compose file you can find preset lables for usage with traefik.
+
+[Traefik Docker Image](https://hub.docker.com/_/traefik/)
+
+Alternativly just use plain old nginx.
