 All changes to SQL should only be made in the `/src/pgstac/sql` directory. SQL Files will be run in alphabetical order.
 
 ### Adding Tests
+
+There are three different types of tests within the project: (1) pgTap tests, (2) basic SQL tests, and (3) PyPgSTAC tests.
+
 PgSTAC tests can be written using PGTap or basic SQL output comparisons. Additional testing is available using PyTest in the PyPgSTAC module. Tests can be run using the `scripts/test` command.
 
-PGTap tests can be written using [PGTap](https://pgtap.org/) syntax. Tests should be added to the `/src/pgstac/tests/pgtap` directory. Any new sql files added to this directory must be added to `/src/pgstac/tests/pgtap.sql`.

 The Basic SQL tests will run any file ending in '.sql' in the `/src/pgstac/tests/basic` directory and will compare the exact results to the corresponding '.sql.out' file.

+### A Note on Hydration and Dehydration
+
+Dehydration refers to stripping redundant attributes of STAC items when storing them within the database. For many collections, dehydration saves a significant amount of memory.
+
+Rehydration is the process of adding the stripped attributes back to the STAC items, such as during the export of an STAC collection or the response to a search query.
+
+PgSTAC, a versatile tool, is designed to seamlessly integrate with PyPgSTAC or alternative backends. This flexibility allows for direct calls for both rehydration and dehydration, giving developers and technical users a sense of control over the process.
+
+Hydration and dehydration are de-facto settings that users can not opt out of. In the future, we may provide a configuration for use cases where the size benefits do not justify the added complexity.
