Setup has two parts: a Teams administrator turns on custom app uploads for your organization, then someone uploads the Topicflow app package we provide. ## Before you start * The **Topicflow app package** — [download the `.zip` file](https://s3.us-west-2.amazonaws.com/www.topicflow.com/assets/topicflow-bot-prod.zip). You'll upload this to Teams in the steps below. * A **Microsoft Teams administrator** to enable custom app uploads (the first step below). Once that's on, uploading the app doesn't require admin permissions. ## Step 1: Enable custom app uploads A Teams administrator only needs to do this once for your whole organization. 1. Go to the [Teams admin center](https://admin.teams.microsoft.com/). 2. Open **Teams apps → Setup policies → Global (Org-wide default)**. 3. Turn **Upload custom apps** on. 4. Select **Save**. Allow a few minutes for the change to take effect across your organization. If your organization already allows custom app uploads, you can skip straight to uploading the app. ## Step 2: Upload the Topicflow app 1. In Microsoft Teams, go to **Apps → Manage your apps → Upload an app**. 2. Choose **Upload a custom app** and select the Topicflow `.zip` file. 3. Confirm the installation when Teams prompts you. ## Step 3: Start using Topicflow Open a chat with the **Topicflow** bot and send a message to get started.
