 # Configure credentials for GitHub Actions Importer
+
+In this lab, you will use the `configure` CLI command to set the required credentials and information for GitHub Actions Importer to use when working with Bitbucket and GitHub.
+
+You will need to complete all of the setup instructions [here](./readme.md#configure-your-codespace) prior to performing this lab.
+
+## Configuring credentials
+
+1. Create a GitHub personal access token (PAT):
+   - Open github.com in a new browser tab.
+   - In the top right of the UI, click your profile photo and then click `Settings`.
+   - In the left panel, click `Developer Settings`.
+   - Click `Personal access tokens` and then `Tokens (classic)` (if present).
+   - Click `Generate new token` and then `Generate new token (classic)`. You may be required to authenticate with GitHub during this step.
+   - Select the following scope: `workflow`.
+   - Click `Generate token`.
+   - Copy the generated PAT and save in a safe location.
+
+2. Create a Bitbucket workspace access token with read scopes for pipeline, project, and repository, using Bitbucket's [documentation](https://support.atlassian.com/bitbucket-cloud/docs/create-a-workspace-access-token/) and store the token in a safe location.
+
+3. Run the `configure` CLI command:
+   - Select the `TERMINAL` tab from within the codespace terminal window.
+   - Run the following command: `gh actions-importer configure`.
+   - Using the down arrow key to highlight `Bitbucket`, press the spacebar to select, and then press enter to continue.
+   - At the GitHub PAT prompt, enter the GitHub PAT generated in step 1 and press enter.
+   - At the GitHub URL prompt, enter the GitHub instance URL or press enter to accept the default value (`https://github.com`).
+   - At the Bitbucket token prompt, enter the Bitbucket access token from step 2 and press enter.
+
+            ```console
+            $ gh actions-importer configure
+            ✔ Which CI providers are you configuring?: Bitbucket
+            Enter the following values (leave empty to omit):
+            ✔ Personal access token for GitHub: ***************
+            ✔ Base url of the GitHub instance: https://github.com
+            ✔ Personal access token for Bitbucket: ***************
+            Environment variables successfully updated.
+            ```
+
+## Verify your environment
+
+To verify your environment is configured correctly, you are going to run the `update` CLI command. The `update` CLI command will download the latest version of GitHub Actions Importer to your codespace.
+
+1. In the codespace terminal run the following command:
+
+   ```bash
+   gh actions-importer update
+   ```
+
+2. You should see a confirmation that you were logged into the GitHub Container Registry and the image was updated to the latest version.
+
+   ```console
+   $ gh actions-importer update
+   Login Succeeded
+   latest: Pulling from actions-importer/cli
+   Digest: sha256:a7d00dee8a37e25da59daeed44b1543f476b00fa2c41c47f48deeaf34a215bbb
+   Status: Image is up to date for ghcr.io/actions-importer/cli:latest
+   ghcr.io/actions-importer/cli:latest
+   ```
