 ### Exploring in Metabase
+
+#### See what your teammates have made
 As long as you're not the very first user in your team's Metabase, the easiest way to start exploring your data is by looking at dashboards, charts, and lists that your teammates have already created. The best place to start is by checking out any dashboards that might be pinned on your home page or in the collections you have access to.
 
+#### Browse your data
 Alternatively, you can dive right in to exploring the data in Metabase by clicking on one of the databases at the bottom of the home page, and then clicking on a table to see it. You can also click on the bolt icon on any table to see an automatic exploration of its data. Give it a try!

 #### Exploring collections
-Collections in Metabase are a lot like folders. They're where all your team's dashboards and charts are kept. To explore a collection just click on one in the "Our analytics" section of the home page, or just click on `Browse all items` to see everything. If your teammates are cool, they'll have pinned some important dashboards or questions within your collections; if so, those important or useful items will show up nice and large at the top of a collection. Collections also have a list of any other items that are saved within them, as well as a list of other collections that are saved inside the current one.

 #### Exploring dashboards
 Dashboards are simply collections of charts and numbers that you want to be able to refer back to regularly. You can learn more about dashboards [here](07-dashboards.md).

-A **segment** is any kind of list or table of things that your company cares about: returning users, orders that used a certain promo code, or sales leads that need to be followed up with are all examples of possible segments.
+Another quick way to start a new question is by clicking on one of your connected databases at the bottom of the homepage, and picking a table that you have a question about. You'll immediately see the table and the graphical question builder so that you can keep exploring.

 ##### Filtering by dates
 
-If filtering by dates, a date picker will appear to allow you to select dates easily. You have two main options for picking your date: relative or specific.
+If filtering by dates, a date picker will appear to allow you to select dates easily, and will default to the previous 30 days.
 
-**Specific Dates**
-This is the most basic way to select dates. You just click on the date you want from the calendar. If you click on a second date, the picker will select all the dates in between the two you clicked on, creating a range. Clicking on any date while you have a range selected will clear the range. You can also use the **All before** and **All after** buttons to quickly select all dates before or after the one you’ve selected.
+Click on the first dropdown to change the kind of date filter you're using. The rest of the popup menu will change depending on this first selection.
 
-**Relative Dates**
-Relative dates are how we more commonly talk about time: “how many customers did we have **last month**?” We talk about time relative to today.
+One important thing to understand when filtering by time or dates like this is the difference between specific and relative dates:
 
-In practice, if you select **Past 30 days** from the Relative Date calendar picker, this would be the same as selecting those same dates from the Specific Date picker — *unless* you save your question and look at it again tomorrow.
+**Specific dates** are things like November 1, 2010, or June 3 – July 12, 2017; they always refer to the same date(s).
 
-Now the relative date will be referencing the past 30 days from *today*, *not* from the day you saved the question. This is a really useful way of creating and saving questions that stay up-to-date: you can always know what your total sales were in the past 7 days, for example.
+**Relative dates** are things like "the past 30 days," or "the current week;" as time passes, the dates these refer to change. Relative dates are a useful way to set up a filter on a question so that it stays up to date by showing you for example how many users visited your website in the last 7 days.
 
 ##### Using segments
-If your Metabase admins have created special named filters, called segments, for the table you’re viewing, they’ll appear at the top of the filter dropdown in purple text with a star next to them. These are shortcuts to sets of filters that are commonly used in your organization. They might be something like “Active Users,” or “Most Popular Products.”

 #### Selecting answer output in the View section

 The next section of the question builder is where you select what you want the output of your answer to be, under the View dropdown. You’re basically telling Metabase, “I want to view…” Metabase can output the answer to your question in four different ways:
 
 ##### 1. Raw data
-Raw Data is just a table with the answer listed in rows.  It's useful when you want to see the actual data you're working with, rather than a sum or average, etc., or when you're exploring a small table with a limited number of records.
