 ## Homework
 
-- TODO(anthonydmays): Assign homework details when available.
+- [ ] Complete [data types exercise](#choosing-the-right-data-types).
+
+### Choosing the Right Data Types
+
+For this exercise, you will use your knowledge of data types to identify the appropriate type to store and process data. You will run a program to generate a unique file with sample data, then write code to provide the correct data type of each column.
+
+1. Execute the app providing a unique provider name.
+
+```bash
+cd lesson_09/types
+./gradlew bootRun --args="yourprovidername" # Substitute with your own value
+```
+2. Examine the file that was created for you in the [resources/data][resources-folder] folder. The file will be formatted using the [JSON][json-link] data format.
+3. Next, you will create a `DataProvider` implementation that will provide information about the data types for the columns in the file (e.g. `column1`, `column2`, etc.). You can view the example [AnthonyMaysProvider.java][example-file] file.
+4. Customize the data types map by choosing the closest appropriate data type of each column. Each data type should only be used **once**.
+5. Make sure to apply the formatter and run the tests to confirm that you've implemented everything correctly.
+```bash
+./gradlew spotlessApply
+./gradlew check
+```
+6. You are to submit a PR with your `DataProvider` implementation and the generated `.json` file that was produced for you. All build checks must pass in order to receive full credit.
+
+### Stretch Assignment - Bulk Sample Generator
+
+In addition to completing the above assignment, you are tasked with adding a flag to the app that will allow it to bulk generate sample files dynamically for each `DataProvider` implementation. Add a short `README.md` doc in the `types_app` folder that explains how to run the app in this custom mode.
