 Depending on your background, the Embassy platform may deal with some unfamiliar concepts. While it is not strictly *necessary* for you to understand these concepts to use your Embassy, we know many of you would like to.

+What is the Embassy?
+====================
+
+The internet as we know it is organized into questioners, or clients, and answerers, or servers. When you open a mobile email app, say Gmail, the app (client) begins asking questions: "have I received new mail?", "what are my last 50 messages?", "what drafts am I in the midst of writing?", and so on. Your app's questions are sent to and heard by a Google-run server which then provides answers back to the client and are subsequently displayed to the screen.
+
+The Embassy is exactly that: your very own "answerer", just like Google's, except managed simply and with ease by and for you alone.
+
+In other words, it is a generalized private personal server capable of running all sorts of self hosted open source software.
+
+When you see your credit card information on your banking app, your messages in your texting app, your passwords in your password management app, all of that information comes from somewhere in the cloud: some server run by some company somewhere on the planet. Who can see the data stored in that server? Who can edit it? It's not always clear, but the increasingly common practice of selling your data to advertisers and the high-profile cyber-security breaches of the last decade suggest a pessimistic outlook.
+
+One thing is for certain though: if you control your server, then you control your data. Your finances, your communications, all of it is actually yours -- and only yours -- with an Embassy.
+
+How does the Embassy work?
+==========================
+
+The Embassy runs on the Raspberry Pi 4B hardware with a Cortex-a72 CPU, 4GB of RAM, and has 2.4ghz and 5.0ghz IEEE 802.11AC wireless capabilities and a BLE internal speaker for audio feedback of system operations. It also features a high endurance MicroSD card, on which the operating system software is installed.
+
+EmbassyOS is a stripped down version of Raspbian Buster Lite and handles all operations of your Embassy device. This core element of the technology stack is what enables you to set up, login, access your Embassy’s dashboard, and download and install services.
+
+One of these operations is creating and managing Tor addresses, which are uniquely attributed to each service you download, as well as to the Embassy device itself. You can see your uniquely generated Tor address when you complete the setup process using the Setup App. This address is how you view your Embassy’s dashboard, which is actually just a website served up from your Embassy itself! It is authenticated, of course, so only you can access it.
+
+You can connect to and manage your Embassy from any mobile device, desktop computer, or laptop computer. This is accomplished right through the browser by visiting your Embassy's private and unique URL.
+
+Once on Embassy's web page, you can choose what services to install to the Embassy. Then, each installed service also receives its own private and unique URL, such that you can access it from the browser or any mobile app that supports using it as a backend.
+
+The list of services will grow rapidly over the coming months, such that many things you currently do using cloud-based third party servers can be just as easily accomplished using your own personal cloud serving your own personal apps and storing your own private data. No trusted third parties at all.
