-- **网格地图模式（Grid Mode）** — 地图页内置 VUCC 网格覆盖图：已通联网格绿色填充、漫游网格蓝色 45° 斜纹（疏朗半透明样式）、当前所在方格淡黄加粗框；点击已通联网格弹出该网格内通联明细弹窗；进入网格模式默认 VUCC 视图
-- **奖状边界模式（Award Boundaries）** — 在网格地图上叠加 DXCC / WAPC / WAJA / WAZ / WAS 国界·省界·分区边界，已确认区域绿色填充
-- **LoTW 网格同步** — 直连 ARRL Logbook（账号密码验证）下载确认报告，worked / roamed 网格自动更新（兼容任意字段顺序的 ADIF 解析）；同步失败按凭据错误/限流/超时分类提示
-- **双站过境匹配（Mutual Pass）** — 输入友台经纬度/网格，筛选双方同时可见的卫星过境，在地图上同时显示双方仰角曲线和地面轨迹，支持一键跳转雷达页查看详情
-- **线性卫星转发器频率计算器** — 在雷达页的 Calculator 标签页中，支持 TX/RX 双向多普勒频率计算，以及下行频率偏移（offset）输入，方便操作带偏移的线性卫星
-- **CW 解码器** — 集成 Morse Expert 解码引擎，支持瀑布图、实时解码文本（arm64 + armeabi-v7a 双架构）
-- **AMSAT 状态页** — 实时查看卫星的业余无线电转发器状态（开启/关闭/待机），支持 72 小时历史记录回放，启动时预取缓存
-- **应用内更新检查** — 设置页一键检查 GitHub 最新 Release，展示版本说明并直接下载安装
-- **自定义 TLE 数据源** — 可添加自定义 TLE/Celestrak CSV 数据源，长按拖拽排序，数据源启停开关与 HTTP 状态码显示
-- **中文界面优化** — 翻译修正、UI 布局调整，系统语言自动切换
+### Track satellite passes with ease!
 
-## 上游仓库
+Thanks to [Celestrak](https://celestrak.com/) and [SatNOGS](https://satnogs.org/) you have access to over 9000 active satellites.\
+You can search the entire database by NORAD Catalog Number or the satellite's name.
 
-本仓库是 [rt-bishop/Look4Sat](https://github.com/rt-bishop/Look4Sat) 的分支，上游仓库的原始功能包括：
+Orbital positions and passes are calculated relative to your location.\
+To get reliable data make sure to set the station position via the app Settings.
 
-- 基于 Celestrak / SatNOGS 数据的 9000+ 活跃卫星追踪
-- SGP4/SDP4 轨道预测，10 天过境预报
-- 极坐标雷达图、地面轨迹图
-- SSTV 图像解码
-- 无广告、无跟踪、完全离线
+The application is built using Kotlin, Coroutines, Jetpack Compose and Navigation.\
+It is now and always will be completely ad-free and open-source.
 
-## 许可证
+## Main features:
 
-GNU General Public License v3.0。详见 [LICENSE](LICENSE)。
+*  Predicting satellite positions and passes for up to 10 days
+*  Showing the list of currently active and upcoming satellite passes
+*  Showing the active pass progress, polar trajectory and transceivers info
+*  Showing the satellite positional data, footprint and ground track on the map
+*  Custom TLE satellite data import is available via Three Line Element .txt files
+*  Offline first: calculations are made offline. Weekly TLE data update is recommended.

- * Minimal PKCS#12 reader for the PBES2/AES-CBC format that OpenSSL 3 and modern
- * TQSL produce by default. Android's legacy bundled Bouncy Castle PKCS12 parser
- * cannot handle PBES2, so we parse the DER structure ourselves and decrypt with
- * the platform JCE (PBKDF2WithHmacSHA1/256 + AES/CBC), which ships on Android.
- *
- * Handles both layouts:
- *  - OpenSSL `-certpbe NONE`: plaintext certificate bags + a PBES2-shrouded key
- *    inside a plaintext `data` ContentInfo.
- *  - Modern TQSL: the certificate SafeContents wrapped in an `encryptedData`
- *    ContentInfo (PBES2), plus the PBES2-shrouded key in a plaintext `data`
- *    ContentInfo.
