+Using a config file
+-------------------
+
+Command line options can also be specified in a config file.
+
+When running ``codespell``, it will check in the current directory for a file
+named ``setup.cfg`` or ``.codespellrc`` (or a file specified via ``--config``),
+containing an entry named ``[codespell]``. Each command line argument can
+be specified in this file (without the preceding dashes), for example::
+
+    [codespell]
+    skip = *.po,*.ts,./src/3rdParty,./src/Test
+    count =
+    quiet-level = 3
+
+This is equivalent to running::
+
+    codespell --quiet-level 3 --count --skip "*.po,*.ts,./src/3rdParty,./src/Test"
+
+Any options specified in the command line will *override* options from the
+config file.
+

    Note that there isn't a comma in the end of the line. The last argument is
    treated as the reason why a suggestion cannot be automatically applied.
 
+Development Setup
+-----------------
+
+You can install required dependencies for development by running the following within a checkout of the codespell source::
+
+       pip install -e ".[dev]"
+
+To run tests against the codebase run::
