+# Provider Packages
+
+Provider packages are used for any integration and are found in their own sub directories.  Providers must adhere to the interface speficied in accountProviders.go. 
+
+```golang
+// AccountProvider is the base set of requirements to be implemented for any integration
+type AccountProvider interface {
+	Name() string                          // Returns the name of the provider
+	Configure() error                      // Configures the provider for first use - if an error is returned the provider is not used
+	GetBalances() ([]int, []string, error) // A slice of balances, and an index mapped slice of ynab account IDs this provider handles is returned
+}
+```
+
+By convention, these methods are implemented in a file called providerImpl.go in each of the provider packages.  
+
+The following providers are currently available:
+
+* bitcoin
+* questrade
+* staticjsonFinnhub
+* staticjsonYahooFinance
