 # How to join Mattermost
+
+Welcome to Open Terms Archive. This document provides guidelines for onboarding new members and contributors joining the Open Terms Archive community on  **Mattermost.**
+
+Open Terms Archive welcomes various contributors, including individual contributors, sponsors, and other entities interested in transparency from the opaqueness of terms by Big Tech services.
+
+## Mattermost platform
+
+Mattermost is an open-source collaboration platform with a simple, user-friendly interface. The Open Terms Archive workspace on Mattermost is divided into different channels, each catering to various aspects of the community. Members are free to join the channels that suit their interests.
+
+## Getting started on Mattermost
+
+1. To get started on Mattermost, an invite link will be sent to new members and contributors.
+2. Once received, they sign up and create an account to log in.
+
+After successful login, they will be redirected to the Open Term Archive workspace, where they will automatically be added to the  **\#announcement** channel.

+
+By default, the Mattermost interface may be presented in French. If this is an issue, new members and contributors can translate the content to English using your browser’s built-in translation features.
+
+## Profile setup
+
+Once you're all set on Mattermost, the next thing is to set up your profile. A complete profile sets you up for meaningful interactions and connections with members interested in tracking the same terms.
+
+This includes adding your full name, user name, pseudo (nickname), role, and profile picture. New members can set up their profiles by following these steps.
+
+1. Navigate to the uppermost right corner of Mattermost and click on the profile icon
+   ![Mattermost profile page]({{< relref "." >}}profile-page.jpg)
+2. Click on the “**Modifier** ” to edit any details of your choice.
+   ![Edit profile page]({{< relref "." >}}edit-profile-page.jpg)
+
+## Adding channels
+
+The Open Terms Archive workspace consists of several channels. Some are specific while others are general. New members and contributors can add any channel of your choice by following these steps:
+
+1. Navigate to the "**CHANNELS**" section on the left-hand sidebar.
+2. Toggle the "**CHANNELS**" button and click on “**Add Channels**”.

+2. Briefly introduce themselves to the community.
