 Abseil contains the following C++ library components:
 
-* [`base`](base/) Abseil Fundamentals
+* [`base`](absl/base/) Abseil Fundamentals
   <br /> The `base` library contains initialization code and other code which
   all other Abseil code depends on. Code within `base` may not depend on any
   other code (other than the C++ standard library).
-* [`algorithm`](algorithm/)
+* [`algorithm`](absl/algorithm/)
   <br /> The `algorithm` library contains additions to the C++ `<algorithm>`
   library and container-based versions of such algorithms.
-* [`container`](container)
+* [`container`](absl/container/)
   <br /> The `container` library contains additional STL-style containers.
-* [`debugging`](debugging)
+* [`debugging`](absl/debugging/)
   <br /> The `debugging` library contains code useful for enabling leak
   checks. Future updates will add stacktrace and symbolization utilities.
-* [`memory`](memory)
+* [`memory`](absl/memory/)
   <br /> The `memory` library contains C++11-compatible versions of
   `std::make_unique()` and related memory management facilities.
-* [`meta`](meta)
+* [`meta`](absl/meta/)
   <br /> The `meta` library contains C++11-compatible versions of type checks
   available within C++14 and C++17 versions of the C++ `<type_traits>` library.
-* [`numeric`](numeric)
+* [`numeric`](absl/numeric/)
   <br /> The `numeric` library contains C++11-compatible 128-bit integers.
-* [`strings`](strings)
+* [`strings`](absl/strings/)
   <br /> The `strings` library contains a variety of strings routines and
   utilities, including a C++11-compatible version of the C++17
   `std::string_view` type.
-* [`synchronization`](synchronization)
+* [`synchronization`](absl/synchronization/)
   <br /> The `synchronization` library contains concurrency primitives (Abseil's
   `absl::Mutex` class, an alternative to `std::mutex`) and a variety of
   synchronization abstractions.
-* [`time`](time)
+* [`time`](absl/time/)
   <br /> The `time` library contains abstractions for computing with absolute
   points in time, durations of time, and formatting and parsing time within
   time zones.
-* [`types`](types)

+* [`types`](absl/types/)
+  <br /> The `types` library contains non-container utility types, like a
   C++11-compatible version of `absl::optional`.
