+The CLI can attach git metadata like `branch`, `commit sha`, `owner` and more when executing the `test --record` and `deploy` commands. This way you can keep track of 
+your test sessions and deployed resources in the UI and cross-reference them with any updates to your code.
+
+For example, in the screenshot below we ran a **test session** from our CI server after the project was deployed to our 
+Staging environment with the `npx checkly test --record` command.
+
+![test session with git info](/images/docs/images/cli/test_session_git_data.png)
+
+After the test succeeds, we **deploy** this check so it runs as a monitor with `npx checkly deploy`.

+
+## Environment variables
+
+The CLI will attempt to auto-detect and parse git specific information from your local machine or CI environment, but you 
+can also set these data items specifically by using environment variables.
+
+<CliEnvVars />
+
+For example, if you want to specifically set the Environment you invoke:
+
+```bash Terminal
+CHECKLY_TEST_ENVIRONMENT=Production npx checkly test --record
+```
+
+Or, if you want to set repo URL you invoke:
+
+```bash Terminal
+CHECKLY_REPO_URL="https://my.git.solution/project/" npx checkly test --record

+Before you can use the Checkly CLI, you need to authenticate with your Checkly account. There are different ways to authenticate depending on the environment where you are running the CLI from.
 
-## Login
+## Interactive
 
-The primary way to authenticate is using the interactive login command:
+When **running the CLI interactively** from your dev environment, just use the built-in `login` command. If you have multiple

 ```bash Terminal
 npx checkly login
 ```
 
-This command will:
-- Open your default browser to the Checkly authentication page
-- Prompt you to log in to your Checkly account
-- Generate an API key that the CLI will use for authentication
-- Store the credentials securely on your local machine
+Once authenticated, you can switch between accounts using:
 
-## Log Out
+```bash Terminal
+npx checkly switch

-To log out and clear your stored credentials:

+description: 'Comparing your options for Monitoring as Code'
+sidebarTitle: 'CLI vs Terraform & Pulumi'
+---
+
+Creating, debugging and managing E2E and synthetic monitoring at scale is best done "as code". Currently, Checkly supports
+three tools you can use for your **monitoring as code** (MaC) workflow:
+
+1. The Checkly CLI.
+2. Terraform (through our [Terraform provider](/integrations/iac/terraform/overview/))
+3. Pulumi (through our [Pulumi provider](/integrations/iac/pulumi/overview/))
+
+In most cases, the choice depends on what your goals are and how your organization is set up.
+
+We believe the **Checkly CLI delivers the best-of-breed workflow**. However, there are always trade-offs. Let's list some 
+pros and cons based on our own experience and user feedback.
+
+## Terraform vs. Checkly CLI
+
+If you are a Terraform shop, you can use Checkly to its full capacity. The Checkly CLI adds core capabilities like TS/JS coding, simple Git integration and test execution.
+
+**Pros**
+
+`+` Terraform integrates very well with Checkly. We have a well maintained Terraform provider.
+
+`+` Terraform is comfortable for many Devops engineers used to writing HCL scripts.
+
+`+` Checkly can be configured almost completely through Terraform resources.
+
+**Cons**
+
+`-` Terraform does not allow you to test checks or use TS/JS programming.
+
+`-` Terraform and its HCL syntax is hard to learn for many app developers.
+
+`-` Using Terraform with Git is non-trivial.
+
+## Pulumi vs. Checkly CLI
+
+**Pros**
+
+`+` Pulumi integrates well with Checkly. We have a maintained Pulumi provider.
+
+`+` Pulumi is comfortable with app developers across many languages.
+
+`+` Checkly can be configured almost completely through Pulumi resources.
+
+**Cons**
+
+`-` Pulumi does not really work without signing up for a Pulumi account.
+
+`-` Pulumi does not allow you to run and debug checks from your local dev environment.
+
+`-` Pulumi is not optimized for testing and monitoring use cases.
