+     "This package provides a variable size buffer pool for Golang.
+
+@code{go-buffer-pool} provides:
+@itemize
+@item @code{BufferPool}: A pool for re-using byte slices of varied sizes.
+This pool will always return a slice with at least the size requested and a capacity
+up to the next power of two.  Each size class is pooled independently which makes the
+@code{BufferPool} more space efficient than a plain @code{sync.Pool} when used in
+situations where data size may vary over an arbitrary range.
+@item @code{Buffer}: a buffer compatible with @code{bytes.Buffer} but backed by a
+@code{BufferPool}.  Unlike @code{bytes.Buffer}, @code{Buffer} will automatically
+shrink on read, using the buffer pool to avoid causing too much work for the
+allocator.  This is primarily useful for long lived buffers that usually sit empty.
