	# Databases
	# ---------

	# ShareLaTeX's main persistant data store is MongoDB (http://www.mongodb.org/)
	# Documentation about the URL connection string format can be found at:
	#
	#    http://docs.mongodb.org/manual/reference/connection-string/
	# 
	# The following works out of the box with Mongo's default settings:
	mongo:
		url : process.env["SHARELATEX_MONGO_URL"] or 'mongodb://dockerhost/sharelatex'

	# Redis is used in ShareLaTeX for high volume queries, like real-time
	# editing, and session management.
	#
	# The following config will work with Redis's default settings:
	redis:
		web: redisConfig =
			host: process.env["SHARELATEX_REDIS_HOST"] or "dockerhost"
			port: process.env["SHARELATEX_REDIS_PORT"] or "6379"
			password: process.env["SHARELATEX_REDIS_PASS"] or ""
		fairy: redisConfig

	# The compile server (the clsi) uses a SQL database to cache files and
	# meta-data. sqllite is the default, and the load is low enough that this will
	# be fine in production (we use sqllite at sharelatex.com).
	#
	# If you want to configure a different database, see the Sequelize documentation
	# for available options:
	#
	#    https://github.com/sequelize/sequelize/wiki/API-Reference-Sequelize#example-usage
	#
	mysql:

			database: "clsi"
			username: "clsi"
			password: ""
			dialect: "sqlite"
			storage: Path.join(DATA_DIR, "db.sqlite")

	# File storage
	# ------------

	# ShareLaTeX can store binary files like images either locally or in Amazon
	# S3. The default is locally:
	filestore:
		backend: "fs"	
		stores:
			user_files: Path.join(DATA_DIR, "user_files")
			template_files: Path.join(DATA_DIR, "template_files")
			
	# To use Amazon S3 as a storage backend, comment out the above config, and
	# uncomment the following, filling in your key, secret, and bucket name:
	#
	# filestore:
	# 	backend: "s3"
	# 	stores:
	# 		user_files: "BUCKET_NAME"
	# 	s3:
	# 		key: "AWS_KEY"
	# 		secret: "AWS_SECRET"
	# 		

	# Local disk caching
	# ------------------
	path:
		# If we ever need to write something to disk (e.g. incoming requests
		# that need processing but may be too big for memory), then write
		# them to disk here:
		dumpFolder:   Path.join(TMP_DIR, "dumpFolder")
		# Where to write uploads before they are processed
		uploadFolder: Path.join(TMP_DIR, "uploads")
		# Where to write the project to disk before running LaTeX on it
		compilesDir:  Path.join(DATA_DIR, "compiles")
		# Where to cache downloaded URLs for the CLSI
		clsiCacheDir: Path.join(DATA_DIR, "cache")

	# The email address which users will be directed to as the main point of
	# contact for this installation of ShareLaTeX.
	adminEmail: process.env["SHARELATEX_ADMIN_EMAIL"] or "placeholder@example.com"
	
	# If provided, a sessionSecret is used to sign cookies so that they cannot be
	# spoofed. This is recommended.
	security:

	# to generate these.

	# them. This should be false in development where changes are being made,

	# -----------------

	# ShareLaTeX is comprised of many small services, which each expose

	# can leave these as they are unless you have some other services
	# running which conflict, or want to run the web process on port 80.
	# internal:
	# 	web:
	# 		port: webPort = 3000
	# 		host: "localhost"
