+- `--language`
+  The language presets to use. You can discover and run tests written in multiple languages by passing this flag multiple times (`--language javascript --language typescript`). Defaults to all supported languages. Currently supported language presets are:
+  - `javascript`:
+    - File RegExp: `^integ\..*\.js$`
+    - App run command: `node {filePath}`
+  - `typescript`:\
+    Note that for TypeScript files compiled to JavaScript, the JS tests will take precedence and the TS ones won't be evaluated.

+  - `python`:
+    - File RegExp: `^integ_.*\.py$`
+    - App run command: `python {filePath}`

 ```bash

+This will search for python integration tests recursively from the current directory and then execute them in parallel across `us-east-1`, `us-east-2`, & `us-west-2`.
 
 If you are providing a list of tests to execute, either as CLI arguments or from a file, the name of the test needs to be relative to the `directory`.
 For example, if there is a test `aws-iam/test/integ.policy.js` and the current working directory is `aws-iam` you would provide `integ.policy.js`
