+# Contributing Guidelines
+If you would like to contribute code to this project you can do so through
+GitHub by forking the repository and sending a pull request.
+
+Please ensure that your contribution does not cause the `pylint` score of the
+package to fall below 9.5. You can check the score with
+
+```
+pylint /path/to/connvitals-monitor/connmonitor/
+```
+
+You may safely ignore the following errors/warnings (by setting this in your
+`~/.pylintrc` file or specifying it on the command line, but please don't
+explicitly ignore these with a pylint directive in-line with the code):
+
+* C0103
+* C0326
+* C0330
+* C0362
+* C0413
+* E1300
+* R0902
+* R0911
+* W0603
+* W0612
+* W1401
+
+The rest of `pylint`'s settings should remain default except that:
+
+* Indentations should be with **tabs only, NEVER spaces**. Spaces may be used
+within an indentation level to align text.
+* Line endings should be unix/line-feed (LF)/'\n' only, **don't** include any
+Windows line endings (carriage-return-then-linefeed (CRLF)/'\r\n' )
+* **All** files in the project **must** end with a newline (leave a blank line
+at the end of the file.)
+
+If there's a good reason you must catch a general `Exception`, state your case
+in the pull request and I'll probably allow it.
+
+Now some comcast stuff:
+
+## CLA

+Before Comcast merges your code into the project you must sign the [Comcast
+Contributor License Agreement

+to when you open a pull request. Alternatively, we can send you a PDF that
+you can sign and scan back to us. Please create a new GitHub issue to request
+a PDF version of the CLA.
