+### Time Durations
+
+Time durations are specified as a number, followed immediately by one of the
+following units:
+
+* `ms` - milliseconds
+* `s` - seconds
+* `m` - minutes
+* `h` - hours
+* `d` - days - assuming a day has always 24h
+* `w` - weeks - assuming a week has always 7d
+* `y` - years - assuming a year has always 365d
+
+Time durations can be combined, by concatenation. Units must be ordered from the
+longest to the shortest. A given unit must only appear once in a time duration.
+
+Here are some examples of valid time durations:

+    5h

 Logrus is a structured logger for Go (golang), completely API compatible with
 the standard library logger.
 
+**Logrus is in maintenance-mode.** We will not be introducing new features. It's
+simply too hard to do in a way that won't break many people's projects, which is
+the last thing you want from your Logging library (again...).
+
+This does not mean Logrus is dead. Logrus will continue to be maintained for
+security, (backwards compatible) bug fixes, and performance (where we are
+limited by the interface). 
+
+I believe Logrus' biggest contribution is to have played a part in today's
+widespread use of structured logging in Golang. There doesn't seem to be a
+reason to do a major, breaking iteration into Logrus V2, since the fantastic Go
+community has built those independently. Many fantastic alternatives have sprung
+up. Logrus would look like those, had it been re-designed with what we know
+about structured logging in Go today. Check out, for example,
+[Zerolog][zerolog], [Zap][zap], and [Apex][apex].
