 ## Style guide
 
-- Write documentation in first person plural ("we"). In our open source code, tutorials and guides can be written by any developer or user, so the documentation teaches all of us how to do something with Parcels.
+- **Write out `parcels.class.method` in tutorials and how-to guides** so that we can see which classes and methods are part of Parcels. If we use `from parcels import class`, the use of `class` in a cell further along is not obviously part of `parcels`.
+- **Import packages at the top of the section in which they are first used** to show what they are used for.
+- **Write documentation in first person plural ("we").** In our open source code, tutorials and guides can be written by any developer or user, so the documentation teaches all of us how to do something with Parcels. Sometimes it can be more natural to take on the tone of a teacher, writing to a student/learner, in which case it is okay to use "you". Please refrain from using impersonal subjects such as "the user".

+Welcome to the **Parcels** quickstart tutorial, in which we will go through all the necessary steps to run a simulation. The code in this notebook can be used as a starting point to run Parcels in your own environment. Along the way we will familiarize ourselves with some specific classes and methods. If you are ever confused about one of these, or how they relate to each other, we have a [concepts overview](concepts_overview.md) to describe how we think about them. Let's dive in!
