 This `MortXML` class is a wrapper around the [underlying XML](https://mort.soa.org/About.aspx). The autocompletions you get on attributes improve the developer experience over using the underlying XML directly.

+## Accessing mortality rates
+
+For a select and ultimate table we can retrieve rates as follows.
 
 ```py
 from pymort import MortXML
+# Table 3265 is 2015 VBT Smoker Distinct Male Non-Smoker ANB, see https://mort.soa.org/

-## Relational tables
-
-Pymort provides **3 normalized tables** related by [primary/foreign keys](https://www.ibm.com/docs/en/ida/9.1.1?topic=entities-primary-foreign-keys), a design taken from relational databases.
-
-Currently tables from 2015 VBT and 2017 CSO are supported. If you want support for tables from other studies, open an issue on GitHub.
-
-XML files with multiple "select" (2-dimensional) or multiple "ultimate" (1-dimensional) tables like table [2636](https://mort.soa.org/ViewTable.aspx?&TableIdentity=2636) are not supported so that we can avoid adding another column.
-
-### Metadata
-
-Each table has a unique identifier called an `id`. There is information associated with this table like
-
-- What is the name of the mortality study producing the table? (i.e. 2017 CSO vs. 2015 VBT)
-- Is there a grouping that the table belongs to within the study? (i.e. unloaded preferred_structure gender_distinct ANB vs. loaded smoker_distinct gender_blended ALB)
-- Gender (male vs. female)
-- Risk (smoker vs. nonsmoker)
-
-We call this information about a table the `metadata` and store it as an attribute of our `Relational` object.
-
-```py
-from pymort import Relational
-
-db = Relational()
-
-print(db.metadata)
-```
-
-![](./assets/meta2.png)
-
-### Select
-
-Select tables depend on the issue age, and the years since issuing the contract.
-
-```py
-print(db.select)
-```
-
-![](./assets/sel2.png)
-
-### Ultimate
-
-Ultimate tables depend on the attained age only.
-
-```py
-print(db.ultimate)
-```
-
-![](./assets/ult2.png)
-
-### Groupings
-
-If you want to get the IDs for all tables having the same study and group there is a function for this, although you could do it yourself in Pandas.
-
-```py
-from pymort import getIdGroup
-
-getIdGroup(3265)
-```
-
-This returns a dataclass representing the grouping.
