 ## Probes
 
-In order to determine the state of particular element of application, probes need to be implemented either by creating [probes from functions](#standard-probes) or by using simple and thread-safe [manual probes](#manual-probes).

-Probes (instances of `Probe` interface) are wrappers for functions that performs user defined logic with given interval of updates in order to determine whether the probe should be marked as healthy or not. Those functions should take no arguments and return error (if no error is returned, the probe is considered to be healthy; if error is returned, the probe is considered to be unhealthy). If given interval is less or equal zero, then function is only checked on probe creation and remains in determined state forever.
