+# This file was generated by edx-lint: https://github.com/openedx/edx-lint
+#
+# If you want to change this file, you have two choices, depending on whether
+# you want to make a local change that applies only to this repo, or whether
+# you want to make a central change that applies to all repos using edx-lint.
+#
+# Note: If your pylintrc file is simply out-of-date relative to the latest
+# pylintrc in edx-lint, ensure you have the latest edx-lint installed
+# and then follow the steps for a "LOCAL CHANGE".
+#
+# LOCAL CHANGE:
+#
+# 1. Edit the local pylintrc_tweaks file to add changes just to this
+#    repo's file.
+#
+# 2. Run:
+#
+#       $ edx_lint write pylintrc
+#
+# 3. This will modify the local file.  Submit a pull request to get it
+#    checked in so that others will benefit.
+#
+#
+# CENTRAL CHANGE:
+#
+# 1. Edit the pylintrc file in the edx-lint repo at
+#    https://github.com/openedx/edx-lint/blob/master/edx_lint/files/pylintrc
+#
+# 2. install the updated version of edx-lint (in edx-lint):
+#
+#       $ pip install .
+#
+# 3. Run (in edx-lint):
+#
+#       $ edx_lint write pylintrc
+#
+# 4. Make a new version of edx_lint, submit and review a pull request with the
+#    pylintrc update, and after merging, update the edx-lint version and
+#    publish the new version.
+#
+# 5. In your local repo, install the newer version of edx-lint.
+#
+# 6. Run:
+#
+#       $ edx_lint write pylintrc
+#
+# 7. This will modify the local file.  Submit a pull request to get it
