+description: 'Verify Setup'
+---
+
+## Goal
+This tool verifies the developer's environment for SDK development and release tasks. It returns what requirements are missing for the specified languages and repo.
+
+Your goal is to identify the project repo root, and pass in the `packagePath` to the Verify Setup tool. For a language repo, pass in the language of the repo.
+
+## Examples
+- in `azure-sdk-for-js`, run `azsdk_verify_setup` with `(langs=javascript, packagePath=<path>/azure-sdk-for-js)`.
+- in `azure-sdk-for-python`, run `azsdk_verify_setup` with `(langs=python, packagePath=<path>/azure-sdk-for-python, venvPath=<path-to-venv>)`.
+
+## Parameter Requirements
+WHENEVER Python is included in `langs`, BEFORE RUNNING `azsdk_verify_setup`, you MUST ASK THE USER TO SPECIFY WHICH virtual environment they want to check. DO NOT ASSUME THE VENV WITHOUT ASKING THE USER. After obtaining the `venvPath`, you can run the tool.
+
+The user can specify multiple languages to check. If the user wants to check all languages, pass in ALL supported languages and STILL ASK for a `venvPath`. Passing in no languages will only check the core requirements.
+
+## Output
+Display results in a user-friendly and concise format, highlighting any missing dependencies that need to be addressed.
