 ## 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.

 ## Deployment
 
+ℹ️ `https` is required otherwise browsers will not support the cryptographic functions.
+
+### Docker
+
 Docker is the easiest way. There is the [official image here](https://hub.docker.com/r/cupcakearmy/cryptgeon).
 
 ```yaml
 # docker-compose.yml
 
-version: '3.7'
+version: '3.8'
 
 services:
-  memcached:
+  redis:
-    image: memcached:1-alpine
+    image: redis:7-alpine
-    entrypoint: memcached -m 128 # Limit to 128 MB Ram, customize at free will.
+    # Set a size limit. See link below on how to customise.
+    # https://redis.io/docs/manual/eviction/
+    command: redis-server --maxmemory 1gb --maxmemory-policy allkeys-lru
 
   app:
     image: cupcakearmy/cryptgeon:latest
     depends_on:
-      - memcache

-- a memcache docker container
+**Install**
-- rust backend with hot reload
-- client with hot reload
 
-You can see the app under [localhost:3000](http://localhost:3000).
+```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:
+
+- redis docker container
+- rust backend
+- client
+
+You can see the app under [localhost:1234](http://localhost:1234).
+
+## Tests
+
+Tests are end to end tests written with Playwright.
+
+```sh
+pnpm run test:prepare
+docker compose up redis -d
+pnpm run test:server
+
+# In another terminal.
+# Use the test or test:local script. The local version only runs in one browser for quicker development.
+pnpm run test:local
+```

+## 关于本项目
+
+_加密鸽_ 是一个受 [_PrivNote_](https://privnote.com)项目启发的安全、开源共享密信和文件共享服务器
+
+> 🌍 如果你想翻译此项目请随时与我联系.
+>
+> 感谢 [Lokalise](https://lokalise.com/) 提供免费的平台服务支持
+
+## 演示示例
+
+查看加密鸽的在线演示 demo： [cryptgeon.org](https://cryptgeon.org)
+
+## 功能
+
+- 服务端无法解密和查看客户端加密的内容
+- 查看次数或时间限制，阅后即焚
+- 您发送的数据将存放于内存中，不会写入到磁盘中
+- 黑暗模式支持
+
+## 加密鸽是如何工作的？
+
+加密鸽会为每条笔记都生成一个独立的 <code>id (256bit)</code> 和 <code>key 256(bit)</code>。
+
+其中<code>id</code>用于保存和提取密信， 在这之后这封密信将会被客户端使用 AES 算法的 GCM 模式和`key`进行加密然后发送至服务器，数据将会保存在服务器的内存中且永远不会被持久化到硬盘上，服务端永远不会得到密钥并且无法解读密信的内容。

+
+## 部署
+
+ℹ️ 加密鸽必须使用`https`，否则浏览器可能将不会支援加密鸽的加密算法。
+
+### Docker
+
+Docker 是最简单的部署方式。这里是[官方镜像的地址](https://hub.docker.com/r/cupcakearmy/cryptgeon)。
+
+附：译者的[部署笔记](https://www.hash070.top/archives/cryptgeon-docker-deploy.html)
+
+```yaml
+# docker-compose.yml
+version: '3.8'
+
+services:
+  redis:
+    image: redis:7-alpine
+
+  app:
+    image: cupcakearmy/cryptgeon:latest
+    depends_on:
+      - redis
+    environment:
+      SIZE_LIMIT: 4 MiB
+    ports:
+      - 80:5000
+```
+
+### NGINX 反向代理
+
+查看 [examples/nginx](https://github.com/cupcakearmy/cryptgeon/tree/main/examples/nginx) 目录。那里有几个示例反代配置文件模板，其中一个是带 https 配置的反代配置模板，你需要指定服务器的名称和证书才能生效。
+
+### Traefik 2
+
+假设:
+
+- 外部 Docker 代理网络 `proxy`
+- 证书解析器 `le`
+- 一个 https 入站点 `secure`
+- 域名 `example.org`
+
+```yaml
+version: '3.8'
+
+networks:
+  proxy:
+    external: true
+
+services:
+  redis:
+    image: redis:7-alpine
+    restart: unless-stopped
+
+  app:
+    image: cupcakearmy/cryptgeon:latest
+    restart: unless-stopped
+    depends_on:
+      - redis
+    networks:
+      - default
+      - proxy
+    labels:
+      - traefik.enable=true
+      - traefik.http.routers.cryptgeon.rule=Host(`example.org`)
+      - traefik.http.routers.cryptgeon.entrypoints=secure
+      - traefik.http.routers.cryptgeon.tls.certresolver=le
+```
+
+## 开发
+
+**环境要求**
+
+- `pnpm`: `>=6`
+- `node`: `>=14`
+- `rust`: edition `2021`
+
+**安装**
+
+```bash
+pnpm install
+pnpm --prefix frontend install
+
+# 你还需要安装CargoWatch.
+# https://lib.rs/crates/cargo-watch
+cargo install cargo-watch
+```
+
+**运行**
+
+确保你的 Docker 正在运行
+
+> 如果你用的是 `macOS` 的话你可能需要关闭 AirPlay 接收功能因为该功能需要占用 5000 端口...)
+> https://developer.apple.com/forums/thread/682332
+
+```bash
+pnpm run dev
+```
+
+在根目录执行 `pnpm run dev` 会开启下列服务:
+
+- 一个 redis docker 容器
+- 无热重载的 rust 后端
+- 可热重载的客户端
+
+你可以通过 1234 端口进入该应用，即 [localhost:1234](http://localhost:1234).
+
+## 测试
+
+这些测试是用 Playwright 实现的一些端到端测试用例。
+
+```sh
+pnpm run test:prepare
+docker compose up redis -d
+pnpm run test:server
+
+# 在另一个终端中：
+# 使用test或者test:local script。为了更快的开发，本地版本只会在一个浏览器中运行。
+pnpm run test:local
+```

-# 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>
-		<i>cryptgeon</i> is a secure, open source sharing note service inspired by
-		<a href="https://privnote.com"><i>PrivNote</i></a>.
-	</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. the note is then encrypted
-		with aes in gcm mode on the client side 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.
-	</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.
-		<br />
-		you are welcomed to check & audit the
-		<a href="https://github.com/cupcakearmy/cryptgeon" target="_blank" rel="noopener">source code</a

+# 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/

+```

+
+Create another docker-compose.yaml file in another folder. We will assume that the domain is `cryptgeon.example.org`.

+## 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.
