+## Indentation
+Never use tabs!
+Use 2 spaces to indent.
+
+## Quotes
+Always use double-quotes!
+Only use single-quotes when the string contains double-quotes that would need to be escaped.
+
+## Capitalization
+Do not use camelCase for variable or function names! Use under_score naming.
+camelCase is okay when used like `import foo.bar.camelCase as camelCase`.
+
+## Aligning variable assignments
+In case you have multiple variable assignments, align the equals sign:
+
+```Python
+# bad
+foo = 1
+foobar = 2
+a = 3
+
+# good
+foo    = 1
+foobar = 2
+a      = 3
+```
+
+Pro Tip: Use the AlignTab plugin for Sublime Text!
+
+## Horizontal spacing
+Use at least one space left and one space right to equals signs, and one space right to colons.
+
+## Vertical spacing
+Leave two empty lines before function definitions. In case you need to use `@hook.something`, add the two lines before that, directly followed by the definition.
+
+## Meaningful names
+Give function and variable names meaningful names. If you want to shorten long names, that's fine, but leave a comment on assigment with the actual meaning.
+
+## Readability
+Don't create long lines with lots of function calls. Split into multiple lines instead.
+Also avoid methods with lots of lines. Split into multiple methods instead.
+
+```Python
+# bad
+foo = int(player_data[str(server.getPlayer(args[4]).getUniqueId())]["details"].["last_login"].strftime("%s"))
+
+# good
+player     = server.getPlayer(args[4])
+player_id  = uid(player)
+logintime  = player_data[played_id]["last_login"]
+epoch_time = int(logintime.strftime("%s"))
+```
+
+## Comments
+Comments are good!
+Please comment everything that's non-obious or makes it easier to understand
+
+## PEP 8
+Please take a look at [PEP 8 - Style Guide for Python Code](https://www.python.org/dev/peps/pep-0008/#code-lay-out) for anything that has not been covered above.
