 Setting configurable options
 ============================
 
 Many of IPython's classes have configurable attributes (see
 :doc:`options/index` for the list). These can be
 configured in several ways.
 
-Python config files

+To create the blank configuration files, run::
 
     ipython profile create [profilename]
 
 If you leave out the profile name, the files will be created for the
 ``default`` profile (see :ref:`profiles`). These will typically be located in
 :file:`~/.ipython/profile_default/`, and will be named
-:file:`ipython_config.py`, for hitorical reasons you may also find fiels
-named with IPytho nprefix instead of Jupyter:
+:file:`ipython_config.py`, for historical reasons you may also find files
+named with IPython prefix instead of Jupyter:
 :file:`ipython_notebook_config.py`, etc. The settings in
 :file:`ipython_config.py` apply to all IPython commands.
 
-by default, configuration files are fully featured Python scripts that can

+By default, configuration files are fully featured Python scripts that can
+execute arbitrary code, the main usage is to set value on the configuration
+object ``c`` which exist in your configuration file.
 
 You can then configure class attributes like this::
 
     c.InteractiveShell.automagic = False
 
 Be careful with spelling--incorrect names will simply be ignored, with
 no error. 
 
 To add to a collection which may have already been defined elsewhere or have
 default values, you can use methods like those found on lists, dicts and
 sets: append, extend, :meth:`~traitlets.config.LazyConfigValue.prepend` (like
 extend, but at the front), add and update (which works both for dicts and
 sets)::
 
     c.InteractiveShellApp.extensions.append('Cython')

         'myextension'
     ]

         'import numpy',
         'import scipy'
     ]

         'mycode.py',
         'fancy.ipy'
     ]
     c.InteractiveShell.colors = 'LightBG'
     c.InteractiveShell.confirm_exit = False
     c.InteractiveShell.editor = 'nano'
     c.InteractiveShell.xmode = 'Context'
 
     c.PrefilterManager.multi_line_specials = True
 
     c.AliasManager.user_aliases = [
      ('la', 'ls -al')
     ]

 ``.py`` configuration files. The following ``ipython_config.json`` file::
 
     {
         "InteractiveShell": {
             "colors": "LightBG",
             "editor": "nano"
         },
         "InteractiveShellApp": {

                 "myextension"
             ]
         }
     }
 
 Is equivalent to the following ``ipython_config.py``::
 
     c.InteractiveShellApp.extensions = [
         'myextension'
     ]
 
     c.InteractiveShell.colors = 'LightBG'
     c.InteractiveShell.editor = 'nano'
 
 
 Command line arguments
 ----------------------
 
 Every configurable value can be set from the command line, using this
 syntax::
 
     ipython --ClassName.attribute=value
 
 Many frequently used options have short aliases and flags, such as
 ``--matplotlib`` (to integrate with a matplotlib GUI event loop) or
 ``--pdb`` (automatic post-mortem debugging of exceptions).
 
 To see all of these abbreviated options, run::
 
     ipython --help
     jupyter notebook --help
     # etc.
 
 Options specified at the command line, in either format, override
 options set in a configuration file.
 
 The config magic
 ----------------
 
 You can also modify config from inside IPython, using a magic command::
 
     %config IPCompleter.greedy = True
 
 At present, this only affects the current session - changes you make to
 config are not saved anywhere. Also, some options are only read when
 IPython starts, so they can't be changed like this.
 
 .. _configure_start_ipython:
 
 Running IPython from Python
 ----------------------------
 
 If you are using :ref:`embedding` to start IPython from a normal 
 python file, you can set configuration options the same way as in a 
 config file by creating a traitlets config object and passing it to 
 start_ipython like in the example below.
 
 .. literalinclude:: ../../../examples/Embedding/start_ipython_config.py
     :language: python
 
 .. _profiles:
 
 Profiles
 ========
 
 IPython can use multiple profiles, with separate configuration and
 history. By default, if you don't specify a profile, IPython always runs
 in the ``default`` profile. To use a new profile::
 
     ipython profile create foo   # create the profile foo
     ipython --profile=foo        # start IPython using the new profile
 
 Profiles are typically stored in :ref:`ipythondir`, but you can also keep
 a profile in the current working directory, for example to distribute it
 with a project. To find a profile directory on the filesystem::
 
     ipython locate profile foo
 
 .. _ipythondir:
 
 The IPython directory
 =====================
 
 IPython stores its files---config, command history and extensions---in
 the directory :file:`~/.ipython/` by default.
 
 .. envvar:: IPYTHONDIR
 
    If set, this environment variable should be the path to a directory,
    which IPython will use for user data. IPython will create it if it
    does not exist.
 
 .. option:: --ipython-dir=<path>
 
    This command line option can also be used to override the default
    IPython directory.
 
 To see where IPython is looking for the IPython directory, use the command
 ``ipython locate``, or the Python function :func:`IPython.paths.get_ipython_dir`.
 
 
 Systemwide configuration
 ========================
 
-It can be usefull to deploy systemwide ipython or ipykernel configuration
+It can be useful to deploy systemwide ipython or ipykernel configuration
 when managing environment for many users. At startup time IPython and
 IPykernel will search for configuration file in multiple systemwide
 locations, mainly:
 
   - ``/etc/ipython/``
   - ``/usr/local/etc/ipython/``
 
 When the global install is a standalone python distribution it may also
 search in distribution specific location, for example:
 
   - ``$ANACONDA_LOCATION/etc/ipython/``
 
 In those locations, Terminal IPython will look for a file called
 ``ipython_config.py`` and ``ipython_config.json``, ipykernel will look for
 ``ipython_kernel_config.py`` and ``ipython_kernel.json``.
 
 Configuration files are loaded in order and merged with configuration on
-later locatoin taking precedence on earlier locations (that is to say a user
+later location taking precedence on earlier locations (that is to say a user
 can overwrite a systemwide configuration option).
 
 You can see all locations in which IPython is looking for configuration files
 by starting ipython in debug mode::
 
     $ ipython --debug -c 'exit()'
 
 Identically with ipykernel though the command is currently blocking until
 this process is killed with ``Ctrl-\``::
  
-    $ python -m ipykernel --debug
  No newline at end of file
+    $ python -m ipykernel --debug
