+-------------------------------------------------------------------------------
+
+Lua fun, also known as the Lua Functional Library, takes advantage
+of the features of LuaJIT to help users create complex functions.
+Inside the package are "sequence processors" such as
+map, filter, reduce, zip -- they take a user-written function as
+an argument and run it against every element in a sequence, which
+can be faster or more convenient than a user-written loop.
+Inside the package are "generators" such as range, tabulate, and
+rands -- they return a bounded or boundless series of values.
+Within the package are "reducers", "filters", "composers" ...
+or, in short, all the important features found in languages like
+Standard ML, Haskell, or Erlang.
+
+The full documentation is `On the luafun section of github`_.
+However, the first chapter can be skipped because installation
+is already done, it's inside Tarantool. All that is needed is the usual require request.
+After that, all the operations described in the
+Lua fun manual will work, provided they are preceded by the
+name returned by the require request.
+For example:
+
+.. code-block:: lua
+
+    localhost> fun = require('fun')
+    localhost> for _k, a in fun.range(3) do print(a) end
+    1
+    2
+    3
+    ---
+    ...
