# How to Install Threadly

In order to use Threadly, the app must be installed into your Slack workspace. You must be a Slack workspace admin (or have admin approval) to install apps.

## 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 the Slack authorization screen. Click **Allow** to grant Threadly the permissions it needs to send messages on your behalf.

## After installation

Once installed, Threadly will appear in your Slack sidebar under **Apps**. Any workspace member can then [authorize their own account](/threadly/getting-started/accessing-threadly-in-slack.md) to start using it — each user connects individually.

{% hint style="info" %}
To send messages to **private channels**, invite Threadly first: type `/invite @Threadly` in that channel.
{% endhint %}
