-
-該專案推薦至少使用 Xcode 13.4.1。更舊版的 Xcode 的話，只要你能跑 Cpp 17 沒問題就行。或者，「`cmake -S . -B Build`」然後到 Build 目錄下執行「`make runTest`」。
+該專案雖使用 Swift Package Manager (SPM) 開發維護+單元測試，但不妨礙在任何平台使用，因為**實體只有「Tekkon.hh」這一個檔案（格式：UTF8 無 BOM）**。
+- 敝倉庫的 ObjC 檔案全都是給 SPM 專用的單元測試腳本。
+
+該專案推薦使用的建置手段：
+- [跨平台 OS] 任何有支援 Cpp17 的 compiler，比如符合這種要求的 Clang 或 GCC。
+- [跨平台 OS] Swift 5.9，以 SPM 的形式建置。
+  - 因為沒有用到任何 Swift 原始碼，所以建置產物對 Swift 不會構成依賴。SPM 在這裡充當了 CMake 的替代角色。 
+- [僅 Apple 平台] 使用 Xcode 的話，須至少 Xcode 15.1。 // Xcode 15.0 因為 Bug 太多的原因不推薦使用。
+
+該專案推薦使用的單元測試手段：
+- SPM 單元測試，直接使用上文提到的 SPM 或 Xcode 即可。
+- GoogleTests，詳見 GTests 目錄下的內容。
+  - 但因為 GoogleTests 官方程式包 Archive 無法在某些國家和地區穩定獲取的緣故，敝倉庫不推薦在這些市場使用這個測試手段。
+  - SPM 可以在 Linux 系統下完成單元測試與建置。
 
 > 注意：該引擎會將「ㄅㄨㄥ ㄆㄨㄥ ㄇㄨㄥ ㄈㄨㄥ」這四種讀音自動轉換成「ㄅㄥ ㄆㄥ ㄇㄥ ㄈㄥ」、將「ㄅㄨㄛ ㄆㄨㄛ ㄇㄨㄛ ㄈㄨㄛ」這四種讀音自動轉換成「ㄅㄛ ㄆㄛ ㄇㄛ ㄈㄛ」。如果您正在開發的輸入法的詞庫內的「甮」字的讀音沒有從「ㄈㄨㄥˋ」改成「ㄈㄥˋ」、或者說需要保留「ㄈㄨㄥˋ」的讀音的話，請按需修改「receiveKeyfromPhonabet()」函式當中的相關步驟、來跳過該轉換。該情形為十分罕見之情形。類似情形則是台澎金馬審音的慣用讀音「ㄌㄩㄢˊ」，因為使用者眾、所以不會被該引擎自動轉換成「ㄌㄨㄢˊ」。威注音輸入法內部已經從辭典角度做了處理、允許在敲「ㄌㄨㄢˊ」的時候出現以「ㄌㄩㄢˊ」為讀音的漢字。我們鼓勵輸入法開發者們使用 [威注音語彙庫](https://gitee.com/vChewing/libvchewing-data) 來實現對兩岸讀音習慣的同時兼顧。
