+### Introduction
+
+The Galaxy community uses [Matrix](https://matrix.org/) – a secure, decentralized, open-source messaging protocol – as its primary chat system. Matrix enables real-time communication across Galaxy contributors, developers, trainers, and users. Common uses include:
+
+* Getting help from the community
+* Discussing tool and workflow development
+* Organizing training events and materials
+* Collaborating on Galaxy infrastructure or scientific questions
+
+Matrix provides an open alternative to proprietary platforms like Slack and Microsoft Teams, with broader flexibility and user privacy in mind.

+
+### 🔰 For Newbies: Getting Started with Matrix
+
+If you are new to messaging systems, here's how to get started with Galaxy on Matrix:
+
+<img src="{% link faqs/galaxy/images/support_matrix_element.jpg %}" alt="Galaxy Project Matrix space using the Element client app" width="350" align="right">
+
+#### Step 1: Choose and install a Matrix app
+
+**Install a Matrix client app:** Download and install a Matrix client:
+
+* [**Element**](https://element.io/) – Recommended. Available on [Web](https://app.element.io), [iOS](https://apps.apple.com/app/element/id1083446067), [Android](https://play.google.com/store/apps/details?id=im.vector.app), [Windows/macOS/Linux](https://element.io/download).&#x20;
+
+* [**Cinny**](https://cinny.in/)
+
+* [**Other Matrix clients...**](https://matrix.org/ecosystem/clients/)
+
+All of these apps connect to the same Galaxy channels/rooms. Choose the interface that works best for you.
+
+#### Step 2: Create a Matrix account
+
+* Open the app and sign up. It's easiest to use the default public server at `matrix.org` for your account.
+* Choose a username. Your Matrix ID will look like: `@yourname:matrix.org`.
+
+#### Step 3: Join the Galaxy **"Lobby"**
+
+* In your Matrix client, join the [main Galaxy chat room - The Lobby](https://matrix.to/#/#galaxyproject_Lobby:gitter.im).
+  * If you're using the Element client, click Explore (the compass icon) and search for "Galaxy" – look for a room named Galaxy or Galaxy Lobby (often with an address like `#galaxyproject:matrix.org`).
+  * Alternatively, you can use a direct Matrix link if provided, which will prompt your app to join the room.
+
+* In addition to the [Lobby room](https://matrix.to/#/#galaxyproject_Lobby:gitter.im), join other Matrix rooms via direct links once logged in:

+
+**Say hello and ask questions:** Once in the Galaxy Lobby, feel free to introduce yourself or ask your question. This Lobby room is a friendly starting point – community members will welcome you, answer basic questions, and guide you to more specific Galaxy channels/rooms if needed. You will be redirected to the right room if needed.

+
+### 💡 For Experienced Users (Slack/Teams/Discord Users)
+
+If you've used tools like Slack, Microsoft Teams, or Discord, Matrix will feel familiar — with a few important differences:
+
+#### ✅ Key Similarities
+
+* **Rooms ≈ Channels**: Rooms are topic-based, like Slack channels.
+* **DMs supported**: You can message users privately.
+* **Multiple devices**: Stay logged in on phone, tablet, laptop.
+
+#### ❗ Key Differences
+
+* **Federated, decentralized network**: There is no single “Galaxy workspace” to be invited to. Join any Matrix room directly via a public server.
+* **Flexible clients**: You can use different Matrix client apps across platforms. They all show the same chats.
+* **Room discovery**: Galaxy may provide a **Matrix Space** to group related rooms to organize communities (e.g. training, user help, development, working groups/wg, infrastructure).
+* **Bridged rooms**: Some rooms are connected to Gitter or other services, but behave normally in Matrix. For example:
+
+  ```
+  #galaxyproject_Lobby:gitter.im
+  ```
+
+  This is a Matrix room that also syncs with users on Gitter. You can treat them as normal Matrix rooms; messages are synced across the platforms.
+
+---
+
+### 🔐 Security and Privacy
+
+Matrix supports **end-to-end encryption (E2EE)** in private conversations and invite-only rooms.
+
+However, **public Galaxy rooms are not encrypted**. This is intentional so people can easily join and search history. Therefore:
+
+* 🔍 **Assume public visibility**: Don't share passwords, private research data, or anything sensitive.
+* 🙈 **Use nicknames if preferred**: Your Matrix ID is visible in public rooms, but you don't have to use your real name.
+* 🔐 **Private DMs are encrypted by default**.
+* ⚠️ **Be cautious**: Even with encryption, nothing is foolproof. Use common sense.
+
+Matrix is designed for open collaboration. When in doubt, treat public rooms like an open forum.
+
+---
+
+### 📍 TL;DR Quickstart
+
+* ✅ Install [Element](https://element.io) or another Matrix app
+* ✅ Create an account (Matrix ID)
+* ✅ Join `#galaxyproject:matrix.org` (Galaxy Lobby)
+* ✅ Ask questions or join other Galaxy rooms from there
+* ❌ Don't share private info in public rooms
