Short: "Secure File Sharing for business",
Long: `Thank you for using Pydio Cells.
Comprehensive sync & share solution for your collaborators. Open-source software deployed on-premise or in a private cloud.
### Installation
For the very first run, use '` + os.Args[0] + ` install' to load browser-based or command-line based installation wizard. Services
will start at the end of the installation.
### Run
Run '` + os.Args[0] + ` start' to load all services.
### Logs level
By default, logs are outputted in console format at the Info level. You can set the --log flag or set the PYDIO_LOGS_LEVEL environment
variable to one of the following values:
- debug, info, error : logs are written in console format with the according level
- production : logs are written in json format, for usage with a log aggregator tool.
### Services Discovery
Micro services need a registry mechanism to discover each other. You don't need to install any dependency.
Cells currently only supports NATS (nats.io) implementation. If a gnatsd service is already running, it will be detected.
### Cells working directories
By default, application data is stored under the standard OS application dir :
- Linux: ${USER_HOME}/.config/pydio/cells
- Darwin: ${USER_HOME}/Library/Application Support/Pydio/cells
- Windows: ${USER_HOME}/ApplicationData/Roaming/Pydio/cells
You can customize the various storage locations with the following ENV variables :
- CELLS_WORKING_DIR : replace the whole standard application dir
- CELLS_DATA_DIR : replace the location for storing default datasources (default CELLS_WORKING_DIR/data)
- CELLS_LOG_DIR : replace the location for storing logs (default CELLS_WORKING_DIR/logs)
- CELLS_SERVICES_DIR : replace location for services-specific data (default CELLS_WORKING_DIR/services)
