+# ABSL Strings
+
+This directory contains packages related to std::string operations and std::string
+alternatives (such as character-agnostic byte manipulation packages).
+
+## Library Listing
+
+Two library targets are available within this directory:
+
+* **strings** (`//absl/strings:strings`) provides classes and
+  utility functions for manipulating and comparing strings, converting other
+  types (such as integers) into strings, or evaluating strings for other usages
+   (such as tokenization).
+
+* **cord** (`//absl/strings:cord`) provides classes and utility
+  functions for manipulating `Cord` elements. A `Cord` is a sequence of
+  characters that internally uses a tree structure to store their data,
+  avoiding the need for long regions of contiguous memory, and allows memory
+  sharing, sub-std::string copy-on-write, and a host of other advanced std::string
+  features.
+
+## Strings Library File Listing
+
+The following header files are directly included within the
+`absl::strings` library.
+
+## Alternate std::string-like Classes
+
+* `bytestream.h`
+    <br/>Abstraction of std::string for I/O
+* `string_view.h`
+    <br/>Pointer to part or all of another std::string
+
+## Formatting and Parsing
+
+* `numbers.h`
+    <br/>Converter between strings and numbers. Prefer `str_cat.h` for numbers
+    to strings
+
+## Operations on Characters
+
+* `ascii_ctype.h`
+    <br/>Char classifiers like &lt;ctype.h&gt; but faster
+* `charset.h`
+    <br/>Bitmap from unsigned char -&gt; bool
+
+## Operations on Strings
+
+* `case.h`
+    <br/>Case-changers
+* `escaping.h`
+    <br/>Escapers and unescapers
+* `str_join.h`
+    <br/>Joiner functions using a delimiter
+* `str_split.h`
+    <br/>Split functions
+* `str_cat.h`
+    <br/>Concatenators and appenders
+* `string_view_utils.h`
+    <br>Utility functions for strings
+* `strip.h`
+    <br/>Character removal functions
+* `substitute.h`
+    <br/>Printf-like typesafe formatter
+
+## Miscellaneous
+
+* `util.h`
+    <br/>Grab bag of useful std::string functions
+
+
+## Cord Library File Listing
+
+The following header files are directly included within the
+`absl::strings::cord` library:
+
+## The `Cord` Class
+
+* `cord.h`
+    <br/>A std::string built from a tree of shareable nodes
+
+## Operations on Cords
+
+* `cord_cat.h`
+    <br/>Concatenator functions for cords
+* `cord_util.h`
+    <br/>Utility functions for cords
