 ## Features
 
 - server cannot decrypt contents due to client side encryption
-- view and time constraints
+- view or time constraints
 - in memory, no persistence
 - obligatory dark mode support
 
 ## How does it work?
 
-each note has a 512bit generated <i>id</i> that is used to retrieve the note. data is stored in memory and never persisted to disk.
+each note has a generated <code>id (256bit)</code> and <code>key 256(bit)</code>. The
+<code>id</code>
+is used to save & retrieve the note. the note is then encrypted with aes in gcm mode on the
+client side with the <code>key</code> and then sent to the server. data is stored in memory and
+never persisted to disk. the server never sees the encryption key and cannot decrypt the contents
+of the notes even if it tried to.

 ## Development
 
-1. Clone
-2. run `npm i` in the root and and client `client/` folders.
-3. Run `npm run dev` to start development.
+**Requirements**
 
-Running `npm run dev` in the root folder will start the following things
+- `pnpm`: `>=6`
+- `node`: `>=14`
+- `rust`: edition `2021`
+
+**Install**
+
+```bash
+pnpm install
+pnpm --prefix frontend install
+
+# Also you need cargo watch if you don't already have it installed.
+# https://lib.rs/crates/cargo-watch
+cargo install cargo-watch
+```
+
+**Run**
+
+Make sure you have docker running.
+
+> If you are on `macOS` you might need to disable AirPlay Receiver as it uses port 5000 (So stupid...)
+> https://developer.apple.com/forums/thread/682332
+
+```bash
+pnpm run dev
+```
+
+Running `pnpm run dev` in the root folder will start the following things:
 
 - a memcache docker container
 - rust backend with hot reload
 - client with hot reload

-# create-svelte
-
-Everything you need to build a Svelte project, powered by [`create-svelte`](https://github.com/sveltejs/kit/tree/master/packages/create-svelte);
-
-## Creating a project
-
-If you're seeing this, you've probably already done this step. Congrats!
-
-```bash
-# create a new project in the current directory
-npm init svelte@next
-
-# create a new project in my-app
-npm init svelte@next my-app
-```
-
-> Note: the `@next` is temporary
-
-## Developing
-
-Once you've created a project and installed dependencies with `npm install` (or `pnpm install` or `yarn`), start a development server:
-
-```bash
-npm run dev
-
-# or start the server and open the app in a new browser tab
-npm run dev -- --open
-```
-
-## Building
-
-Before creating a production version of your app, install an [adapter](https://kit.svelte.dev/docs#adapters) for your target environment. Then:
-
-```bash
-npm run build
-```
-
-> You can preview the built app with `npm run preview`, regardless of whether you installed an adapter. This should _not_ be used to serve your app in production.

-	</p>
-
-	<p>
-		<b>▶ how does it work?</b>
-		<br />
-		each note has a 512bit generated <i>id</i> that is used to retrieve the note. data is stored in memory
-		and never persisted to disk.
-	</p>
-
-	<b>▶ Features</b>
-	<ul>
-		<li>server cannot decrypt contents due to client side encryption</li>
-		<li>view and time constraints</li>
-		<li>in memory, no persistence</li>
-	</ul>
-
-	<p>
-		<b>▶ tech stack</b>
-		<br />
-		the backend is written in rust and the frontend is svelte and typescript.

+# Install from scratch.
+
+This is a tiny guide to install cryptgeon on (probably) any unix system (and maybe windows?) from scratch using traefik as the proxy, which will manage certificates and handle https for us.
+
+1. Install Docker & Docker Compose.
+2. Install Traefik.
+3. Run the cryptgeon.
+4. [Optional] install watchtower to keep up to date.
+
+## Install Docker & DOcker Compose
+
+- [Docker](https://docs.docker.com/engine/install/)
+- [Compose](https://docs.docker.com/compose/install/)
+
+## Install Traefik 2.0
+
+[Traefik](https://doc.traefik.io/traefik/) is a router & proxy that makes deployment of containers incredibly easy. It will manage all the https certificates, routing, etc.
+
+```sh
+/foo/bar/traefik/
+├── docker-compose.yaml
+└── traefik.yaml
+```
+
+```yaml
+# docker-compose.yaml

+
+**Run**
+
+```sh
+docker network create proxy
+docker-compose up -d

+
+## Cryptgeon
+
+Create another docker-compose.yaml file in another folder. We will assume that the domain is `cryptgeon.example.org`.
+
+```sh
+/foo/bar/cryptgeon/

+```
+

+
+```sh
+docker-compose up -d

+
+## Watchtower
+
+> A container-based solution for automating Docker container base image updates.
+
+[Watchtower](https://containrrr.dev/watchtower/) will keep our containers up to date. The interval is set to once a day and also configured to delete old images to prevent cluttering.

+```sh
