+#### Config And Data Directories
+
+The directories MS uses for **Configuration** (`config.json`, `jellyfin.json`, etc...) and **Data** (database, cache, etc...) can be specified by environmental variables passed directly to `npm`/`node`, or set in an `.env` file in the working directory.
+
+When parsing these ENVs MS will resolve relative directories but *not* bash expansions like `~` for home. Examples:
+
+* `CONFIG_DIR=/my/absolute/path` => sets directory to use for config files
+* `DATA_DIR=./relative/data` => sets directory relative to working directory for data files
+
+If you do not set these environmental variables then MS will attempt to use OS-standardized directories:
