 # Identity and access management

 ## Introduction
 
 In this demo, you'll learn how to use TypeDB as the database for an identity and access management system. We'll cover
 some basic operations like listing the users in the system and see how queries can be simplified by taking advantage of
 TypeDB's in-built type-inference and polymorphism, then move on to some more advanced examples that take advantage of
-rule-inference. We'll see how we can automate permission inheritance and enforce a dynamic segregation-of-duty policy at
+TypeQL functions. We'll see how we can automate permission inheritance and enforce a dynamic segregation-of-duty policy at

 ## Getting started
 
-Start your TypeDB server and open TypeDB Studio. Make sure you are on a `schema-write` transaction and run the following

 Remember to click on the green tick after running each of these scripts to commit the changes to the database.
 
 ## Running the examples
 
 To get started, try running the examples. They are intended to be run once each and in order, so be aware that running
-them more than once or out of order might generate data errors. If anything goes wrong, you can run the
-`insert-data.tql` script again to reset everything. All the examples use `data` sessions, but you'll have to switch
-between `read` and `write` transactions depending on the queries in the example, and remember to commit after writes.

 ## Next steps
 
 Once you've tried the pre-written examples out, have a go at editing them or writing something yourself. The schema also
 has a lot of types that are not used in the example dataset, so try experimenting with those. Remember you can view the
 list of types in the Type Browser, or view the schema in the graph visualizer by running the query:
 
-```match $t sub thing;```
+```match $t sub $s;```
