# How to Install Threadly

Install Threadly in your Slack workspace in about two minutes. No code required: click, authorize, and start broadcasting.

Threadly has to be installed in your Slack workspace before anyone can use it. Depending on your workspace settings, you may need to be a Slack admin, or have an admin approve the app.

## Install Threadly

[**Click here to install Threadly →**](https://slack.com/oauth/v2/authorize?client_id=2573203509911.7020858675504\&scope=chat:write,chat:write.customize,commands,files:read,reactions:read,team.billing:read,team:read,users:read,users:read.email\&user_scope=channels:read,channels:write.invites,chat:write,groups:read,groups:write.invites,mpim:read)

This opens Slack's authorization screen. Click **Allow** to grant Threadly the permissions it needs.

## After installation

* Threadly appears in your Slack sidebar under **Apps**.
* The person who installs Threadly becomes its first **admin**. Admins manage billing, [Pro seats](/threadly/admin-and-billing/how-to-add-a-user-to-threadly.md) and team-wide integrations.
* Everyone else [opens Threadly and authorizes their own account](/threadly/getting-started/accessing-threadly-in-slack.md). Each person does this once.

{% hint style="info" %}
To send messages to **private channels**, invite Threadly first by typing `/invite @Threadly` in the channel.
