+## توافقنامه‌ی مجوز همکاری
+
+مشارکت در این مخزن به معنی موافقت شما با مجوز [LICENSE](https://github.com/EbookFoundation/free-programming-books/blob/master/LICENSE) این مخزن است.
+
+
+## مرام‌نامه‌ی همکار
+
+مشارکت در این پروژه به معنی موافقت با احترام به [مرام‌نامه‌ی](https://github.com/EbookFoundation/free-programming-books/blob/master/CODE_OF_CONDUCT.md) این مخزن است.
+
+
+## به طور خلاصه
+
+1. "لینکی برای دانلود ساده‌ی یک کتاب" همیشه به معنی لینکی به یک کتاب *رایگان* نیست. لطفا فقط محتوای رایگان را قرار دهید. مطمئن شوید که این محتوا رایگان است. ما لینک‌هایی را که وارد کردن ایمیل کاری را برای دانلود کتاب *اجباری* کرده‌اند نمی‌پذیریم اما اگر بدون اجبار، این ایمیل را بخواهند، در این مخزن فهرستشان می‌کنیم.
+2. نیاز نیست گیت بلد باشید: اگر چیز جذابی پیدا کردید که *در این مخزن وجود ندارد*، یک [Issue](https://github.com/EbookFoundation/free-programming-books/issues) با نوشتن لینک‌ها درست کنید.
+    * اگر گیت می‌دانید، لطفا مخزن را فورک کنید و پول‌ریکوئست بفرستید.
+3. ما پنج نوع فهرست داریم. فهرست درست را انتخاب کنید:
+
+    * *کتاب‌ها* : PDF، HTML، ePub، سایت بر اساس gitbook.io، یک مخزن گیت و غیره.
+    * *دوره‌ها* : دوره محتوایی آموزشی است که کتاب نیست. مثلا [این یک دوره است](http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-006-introduction-to-algorithms-fall-2011/).
+    * *آموزش‌های تعاملی* : وبسایتی تعاملی که به کاربر اجازه‌ی تایپ کد یا دستور می‌دهد و نتیجه را ارزیابی می‌کند (منظور ما از "ارزیابی"، "نمره‌دهی" نیست). مثلا: [Try Haskell](http://tryhaskell.org), [Try Github](http://try.github.io).
+    * *پادکست‌ها و اسکرین‌کست‌ها*
+    * *مجموعه مشکلات و برنامه‌نویسی رقابتی* : وبسایت یا نرم‌افزاری که به شما امکان بررسی مهارت‌های برنامه‌نویسی را با کمک حل مشکلات ساده یا پیچیده، با یا بدون بررسی کد، با یا بدون مقایسه‌ی نتایج با کاربران دیگر می‌دهد.
+
+4. مطمئن شوید که از [راهنماها](#راهنماها) پیروی می‌کنید و طبق [فرمت‌بندی مارک‌داون](#فرمت‌بندی] می‌نویسید.
+
+5. Travis CI تست‌هایی را اجرا می‌کند که مطمئن شود فهرست شما الفبایی است و قوانین فرمت‌بندی رعایت شده است. مطمئن شوید که تغییرات شما تست‌ها را با موفقیت گذرانده است.
+
+
+### راهنماها
+
+* مطمئن شوید که یک کتاب رایگان است. اگر لازم بود، دوباره هم بررسی کنید. اگر درباره‌ی علت این که فکر می‌کنید کتاب رایگان است در پول‌ریکوئست، کامنت بگذارید، به ادمین‌ها کمک کرده‌اید.
+* ما فایل‌هایی را قبول نمی‌کنیم که روی گوگل‌درایو، دراپ‌باکس، مگا، اسکریبد، ایسیو یا پلتفرم‌های آپلود فایل مشابه قرار دارند
+* لینک‌های خود را به ترتیب الفبایی وارد کنید. اگر لینکی را خارج از ترتیب درست دیدید، لطفا مرتیش کنید و یک پی‌آر ثبت کنید
+* از لینک معتبرترین منبع استفاده کنید (این یعنی وبسایت نویسنده بهتر از وبسایت ویراستار و وبسایت ویراستار بهتر از وبسایت سوم شخص است)
+    * از سرویس‌های اشتراک‌گذاری فایل استفاده نکنید (این سرویس‌ها شامل (و نه محدود به) لینک‌های دراپ‌باکس و گوگل‌درایو است)
+* همیشه یک لینک `https` به یک لینک `http` ترجیح داده می‌شود -- تا وقتی که هر دو لینک دامنه‌ی یکسانی داشته باشند و محتوای یکسانی نمایش دهند.
+* در دامنه‌های اصلی، از گذاشتن / خودداری کنید: `http://example.com` به جای `http://example.com/`
+* همیشه کوتاه‌ترین لینک ترجیح داده می‌شود: `http://example.com/dir/` بهتر است از `http://example.com/dir/index.html`
+    *  از لینک‌های کوتاه‌ساز استفاده نکنید.
+* معمولا لینک "فعلی" بهتر از لینک "نسخه‌ها" است: `http://example.com/dir/book/current/` بهتر است از `http://example.com/dir/book/v1.0.0/index.html`
+* اگر لینکی مشکل certificate/self-signed certificate/SSL از هر نوع دیگری داشت:
+  1. با همتای `http` همان لینک *جایگزینش کنید* (چون پذیرش استثناقائل شدن برای آن وبسایت در دستگاه‌های موبایل سخت است).
+  2. اگر نسخه‌ی `http` ندارد اما همچنان با `https` و اضافه کردن استثناقائل‌شدن برای آن وبسایت در مرورگر یا نادیده گرفتن هشدار قابل دسترس است، *به همان حالت بگذاریدش*
+  3. در غیر این صورت *حذفش کنید*
+* اگر لینکی در چندین فرمت وجود داشت، لینکی جدا با یادداشتی درباره‌ی هر فرمت قرار دهید.
+* اگر منبعی در جاهای دیگری از اینترنت وجود دارد
+    * از لینک معتبرترین منبع استفاده کنید (این یعنی وبسایت نویسنده بهتر از وبسایت ویراستار و وبسایت ویراستار بهتر از وبسایت سوم شخص است)
+    * اگر به ویرایش‌های مختلف لینک شده است و شما معتقدید این ویرایش‌ها به حد کافی متفاوت هستند که هر دو نگه داشته شوند، یک لینک جدا با یادداشتی درباره‌ی هر ویرایش بنویسید (برای مشارکت در فرمت‌بندی [Issue #2353](https://github.com/EbookFoundation/free-programming-books/issues/2353) را ببینید).
+* کامیت‌های تکی (یک کامیت اضافه کردن/ حذف کردن/ تغییر دادن) بهتر از کامیت‌های بزرگ هستند. نیاز نیست کامیت‌های خود را قبل از ثبت یک پی‌آر خرد کنید (ما به دنبال اجباری کردن این قانون نیستیم چون این قانون فقط به خاطر راحتی نگه‌دارندگان مخزن است)
+* اگر کتاب قدیمی است، تاریخ انتشار را در کنار عنوان بنویسید.
+* نام نویسنده یا نویسندگان را در صورت امکان بنویسید. می‌توانید فهرست نویسندگان را با "و همکاران" کوتاه کنید.
+* اگر کتاب هنوز تمام نشده است و هنوز روی آن کار می‌شود، عبارت "in process" را همان طور که در [پایین صفحه](#in_process) آمده به آن اضافه کنید.
+* اگر پیش از دانلود، نشانی ایمیل یا ساخت حساب کاربری خواسته می‌شود، در پرانتز توضیح متناسبی بنویسید. مثلا: `(نشانی ایمیل *خواسته می‌شود* اما اجباری نیست)`
+
+
+### فرمت‌بندی
+
+* همه فهرست‌ها فایل‌های ".md" هستند. سعی کنید دستور زبان [Markdown](https://guides.github.com/features/mastering-markdown/) را یاد بگیرید. ساده است!
+* همه فهرست‌ها با یک فهرست محتوایی شروع می‌شود. ایده این است که همه بخش‌ها و زیربخش‌ها در این فهرست محتوایی لیست و لینک شوند. این فهرست محتوایی را به ترتیب الفبایی قرار دهید.
+* بخش‌ها از تیترهای سطح 3 (`###`) استفاده می‌کنند و زیربخش‌ها از تیترهای سطح 4 (`###`).
+ایده این است که این موارد رعایت شوند:
+* `2` خط خالی بین آخرین لینک و بخش جدید
+* `1` خط خالی بین تیتر و لینک اول همان بخش
+* `0` خط خالی بین دو لینک
+* `1` خط خالی در آخر هر فایل `.md`
+مثال:
+
+    [...]
+    * [یک کتاب عالی](http://example.com/example.html)
+                                    (خط خالی)
+                                    (خط خالی)
+    ### مثال
+                                    (خط خالی)
+    * [یک کتاب عالی دیگر](http://example.com/book.html)
+    * [یک کتاب دیگر](http://example.com/other.html)
+
+* بین `]` و `(` space نگذارید:
+
+```
+بد : * [یک کتاب عالی دیگر] (http://example.com/book.html)
+خوب: * [یک کتاب عالی دیگر](http://example.com/book.html)
+```
+
+* اگر اسم نویسنده را اضافه می‌کنید، از ` - ` استفاده کنید (یک dash با دو single space):
+
+```
+بد : * [یک کتاب عالی دیگر](http://example.com/book.html)- نام نویسنده
+خوب: * [یک کتاب عالی دیگر](http://example.com/book.html) - نام نویسنده
+```
+
+* یک single space بین لینک و فرمت قرار دهید:
+
+```
+بد : * [یک کتاب خیلی عالی](https://example.org/book.pdf)(PDF)
+خوب: * [یک کتاب خیلی عالی](https://example.org/book.pdf) (PDF)
+```
+
+* نویسنده قبل از فرمت می‌آید:
+
+```
+بد : * [یک کتاب خیلی عالی](https://example.org/book.pdf)- (PDF) نام نویسنده
+خوب: * [یک کتاب خیلی عالی](https://example.org/book.pdf) - یک نویسنده دیگر (PDF)
+```
+
+* چند فرمتی‌ها:
+
+```
+بد : * [یک کتاب عالی دیگر](http://example.com/)- نام نویسنده (HTML)
+بد : * [یک کتاب عالی دیگر](https://downloads.example.org/book.html)- نام نویسنده (download site)
+خوب: * [یک کتاب عالی دیگر](http://example.com/) - نام نویسنده (HTML) [(PDF, EPUB)](https://downloads.example.org/book.html)
+```
+
+* سال انتشار برای کتاب‌های قدیمی را در عنوان ینویسید:
+
+```
+بد : * [یک کتاب خیلی عالی](https://example.org/book.html) - نام نویسنده - 1970
+خوب: * [یک کتاب خیلی عالی (1970)](https://example.org/book.html) - نام نویسنده
+```
+
+<a name="in_process"></a>
+* کتاب‌های در دست تالیف:
+
+```
+خوب: * [کتابی که عالی خواهدشد](http://example.com/book2.html) - نام نویسنده (HTML) (:construction: *in process*)
+```
+
+### خودکارسازی
+
+* قوانین فرمت‌بندی از طریق [Travis CI](https://travis-ci.com) با استفاده از [fpb-lint](https://github.com/vhf/free-programming-books-lint) بررسی می‌شوند ([.travis.yml](.travis.yml) را ببینید)
+* اعتبارسنجی لینک‌ها با استفاده از [awesome_bot](https://github.com/dkhamsing/awesome_bot) انجام می‌شود.
+* برای اجرای اعتبارسنجی لینک‌ها، کامیتی پوش کنید که در بدنه‌ی آن `check_urls=file_to_check` نوشته شده باشد:
+
+```
+check_urls=free-programming-books.md free-programming-books-en.md
+```
+
+* با استفاده از single space برای جدا کردن هر ورودی، می‌توانید بیشتر از یک فایل را برای بررسی مشخص کنید.
+* اگر بیش از یک فایل را مشخص کردید، نتایج بیلد بر اساس نتیجه آخرین فایل بررسی‌شده خواهد بود. دقت کنید که ممکن است به همین علت، نتیجه سبز را ببینید. پس برای اطمینان لاگ بیلد را با کلیک روی "Show all checks" -> "Details" در پایان پول ریکوئست ببینید.

+
+
+## 概要
+
+1. "一個可以輕易下載一本書的連結" 並不代表它導向的就是 *免費* 書籍。 請只提供免費內容。 確信你所提供的書籍是免費的。我們不接受導向*需要*工作電子郵件地址才能獲取書籍页面的連結，但我們歡迎有需求這些連結的列表。
+
+2. 你不需要會 Git：如果你發現了一些有趣的東西 *尚未出现在此 repo* 中，請開一個[Issue](https://github.com/EbookFoundation/free-programming-books/issues)進行主題討論。
+    * 如果你已經知道 Git，請 Fork 此 repo 並提交 PR。
+
+3. 這裡有五種列表，請選擇正確的一項：
+
+    * *Books* ：PDF、HTML、ePub、基於 gitbook.io 的網站、Ｇit 的 repo 等。
+    * *Courses* ：課程是一種學習素材，而不是一本書 [This is a course](http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-006-introduction-to-algorithms-fall-2011/)。
+    * *Interactive Tutorials* ：一個互動式網站，允許用戶輸入程式碼或指令並執行結果。例如：[Try Haskell](http://tryhaskell.org)，[Try Github](http://try.github.io)。
+    * *Podcasts and Screencasts* ：Podcast 和影音。
+    * *Problem Sets & Competitive Programming* ：一個網站或軟體，讓你透過解決簡單或複雜的問題來評估你的程式技能，可能有程式碼檢查，或與其他用戶比對结果。
+
+4. 確保遵循下方的[基本準則](#基本準則)，並遵循此 repo 文件的[Markdown規定格式](#規定格式)。
+
+5. Travis CI 將運行測試，以確保你的列表是 **按字母顺序排列** 的，並 **遵循格式化規則**。請 **確保** 你的更改通過該測試。
+
+
+### 基本準則
+
+* 確保你提交的每一本書都是免費的。如有需要請 Double-check。如果你在 PR 中註明為什麼你認為這本書是免費的，這對管理員是很有幫助的。
+* 我們不接受儲存在 google drive、dropbox、mega、scribd、issuu 和其他類似文件上傳平台上的文件。
+* 請按照字母顺序插入連結。如果你看到一個錯位的連結，請重新對他進行排序並提交一個 PR。
+* 使用最權威來源的連結(意思是原作者的網站比編輯的網站好，比第三方網站好)。
+    * 沒有文件託管服務(包括(但不限於)Dropbox和 Google Drive 連結)。
+* 優先選擇使用 `https` 連結，而不是 `http` 連結 -- 只要它們位於相同的網域並提供相同的内容。
+* 在網域根目錄上，去掉尾末的斜槓：使用 `http://example.com` 代替 `http://example.com/`。
+* 優先選擇最短的連結：使用 `http://example.com/dir/` 比使用 `http://example.com/dir/index.html` 更好。
+    * 不要提供短連結
+* 優先選擇使用 "current" 連結代替有 "version" 連結：使用 `http://example.com/dir/book/current/` 比使用 `http://example.com/dir/book/v1.0.0/index.html` 更好。
+* 如果一個連結存在過期的證書/自簽名證書/SSL問題的任何其他類型：
+  1. *replace it* ：如果可能的話，將其 *替換* 為對應的`http`(因為在移動設備上接受異常可能比較複雜)。
+  2. *leave it* ：如果没有http版本，但仍然可以通過https造訪連結，則在瀏覽器中添加異常或忽略警告。
+  3. *remove it* ：上述狀況以外則删除掉它。
+* 如果一個連結以多種格式存在，請添加一個單獨的連結，並註明每種格式。
+* 如果一個資源存在於Internet上的不同位置
+    * 使用最權威來源的連結(意思是原始作者的網站比編輯的網站好，比第三方網站好)。
+    * 如果它們連結到不同的版本，你認為這些版本差異很大，值得保留，那麼添加一個單獨的連結，並對每個版本做說明(參考[Issue #2353](https://github.com/EbookFoundation/free-programming-books/issues/2353)有助於格式化問题的討論)。
+* 相較一個比較大的提交，我們更傾向於原子提交(通過添加/删除/修改進行一次提交)。在提交PR之前没有必要壓縮你的提交。(為了維護人員的方便，我們永遠不會執行這個規則)。
+* 如果一本書比較舊，請在書名中註明出版日期。
+* 包含作者的名字或適當的名字。中文版本可以用 “等” 縮短作者列表。
+* 如果一本書還没有完成，並且仍在編寫中，則需添加 “編寫中” 符號，參考[下文](#in_process)所述。
+* 如果在開始下載之前需要電子郵件地址或帳户設置，請在括號中添加合適的語言描述，例如：`(*需要*電子郵件，但不是必需的)`。
+
+
+### 規定格式
+
+* 所有列表都是`.md`文件。試着學習[Markdown](https://guides.github.com/features/mastering-markdown/)語法。它很容易上手！
+* 所有的列表都以索引開始。它的作用是列出並連結所有的sections(章節/段落)或subsections(子段落/子章節)。務必遵循字母顺序排列。
+* Sections(章節/段落)使用3级標题(`###`)，subsections(子段落/子章節)使用4级標题 (`####`)。
+
+
+#### 整體思維為：   
+
+* `2` ：新添加的Section與末尾連結間必需留有`2`個空行
+* `1` ：標题和第一個連結之間必需留有`1`個空行的空行
+* `0` ：任何兩個連結之間不能留有任何空行
+* `1` ：每個`.md`文件末尾必需留有`1`個空行
+
+
+#### 舉例：   
+
+```
+[...]
+* [一本很有用的書](http://example.com/example.html)
+                                (空行)
+                                (空行)
+### 電子書種類標题
+                                (空行)
+* [Another 很有用的書](http://example.com/book.html)
+* [Other 有用的書](http://example.com/other.html)
+```
+
+* 在 `]` 和 `(` 之間不要留有空格：
+
+```
+錯誤：* [一本很有用的書] (http://example.com/book.html)
+正確：* [一本很有用的書](http://example.com/book.html)
+```
+
+* 如果包括作者，請使用' - '(由單個空格(英文半型)包圍的破折號)：
+
+```
+錯誤：* [一本很有用的書](http://example.com/book.html)- 張顯宗
+正確：* [一本很有用的書](http://example.com/book.html) - 張顯宗
+```
+
+* 在連結和電子書格式之間放一個空格：
+
+```
+錯誤：* [一本很有用的書](https://example.org/book.pdf)(PDF)
+正確：* [一本很有用的書](https://example.org/book.pdf) (PDF)
+```
+
+* 如需備注或注解，請使用英文半型括號`( )`：
+
+```
+錯誤：* [一本很有用的書](https://example.org/book.pdf) （繁體中文）
+正確：* [一本很有用的書](https://example.org/book.pdf) (繁體中文)
+```
+
+* 作者在電子書格式之前：

+
+
+## 贡献者行为准则
+
+请同意并遵循此[行为准则](https://github.com/EbookFoundation/free-programming-books/blob/master/CODE_OF_CONDUCT.md)参与贡献。
+
+
+## 概要
+
+1. "一个可以轻易下载一本书的链接" 并不代表它指向的就是 *免费* 书籍。 请只提供免费内容。 确信你所提供的书籍是免费的。我们不接受指向*需要*工作电子邮件地址才能获取书籍的页面的链接，但我们欢迎有需求它们的列表。
+2. 你不需要会 Git：如果你发现了一些有趣的东西 *尚未出现在本仓库* 中，请开一个[Issue](https://github.com/EbookFoundation/free-programming-books/issues)进行主题讨论。
+    * 如果你已经知晓Git，请Fork本仓库并提交PR。
+3. 这里有5种列表，请选择正确的一个：
+
+    * *Books* ：PDF、HTML、ePub、基于一个 gitbook.io的站点、一个Git仓库等等。
+    * *Courses* ：课程是一种学习材料，而不是一本书 [This is a course](http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-006-introduction-to-algorithms-fall-2011/)。
+    * *Interactive Tutorials* ：一个交互式网站，它允许用户输入代码或命令并对结果进行评估。例如：[Try Haskell](http://tryhaskell.org)，[Try Github](http://try.github.io)。
+    * *Podcasts and Screencasts* ：播客和视频。
+    * *Problem Sets & Competitive Programming* ：一个网站或软件，让你通过解决简单或复杂的问题来评估你的编程技能，有或没有代码审查，有或没有与其他用户对比结果。
+
+4. 确保遵循下面的[基本准则](#基本准则)，并遵循本仓库文件的[Markdown规定格式](#规定格式)。
+
+5. Travis CI 将运行测试，以确保你的列表是 **按字母顺序排列** 的，并 **遵循格式化规则**。请 **确保** 你的更改通过了该测试。
+
+
+### 基本准则
+
+* 确保你提交的每一本书都是免费的。如有需要请做Double-check。如果你在PR中注明为什么你认为这本书是免费的，这将对管理员是很有帮助的。
+* 我们不接受存储在google drive、dropbox、mega、scribd、issuu和其他类似文件上传平台上的文件。
+* 请按照字母顺序插入链接。如果你看到一个错位的链接，请重新对他进行排序并提交一个PR。
+* 使用最权威来源的链接(意思是原作者的网站比编辑的网站好，比第三方网站好)。
+    * 没有文件托管服务(包括(但不限于)Dropbox和谷歌驱动器链接)。
+* 优先选择使用 `https` 链接，而不是 `http` 链接 -- 只要它们位于相同的域并提供相同的内容。
+* 在根域上，去掉末尾的斜杠：使用 `http://example.com` 代替 `http://example.com/`。
+* 总是选择最短的链接：使用 `http://example.com/dir/` 比使用 `http://example.com/dir/index.html` 更好。
+    * 不要提供短链接
+* 优先选择使用 "current" 链接代替有 "version" 链接：使用 `http://example.com/dir/book/current/` 比使用 `http://example.com/dir/book/v1.0.0/index.html` 更好。
+* 如果一个链接存在过期的证书/自签名证书/SSL问题的任何其他类型：
+  1. *replace it* ：如果可能的话，将其 *替换* 为对应的`http`(因为在移动设备上接受异常可能比较复杂)。
+  2. *leave it* ：如果没有http版本，但仍然可以通过https访问链接，则在浏览器中添加异常或忽略警告。
+  3. *remove it* ：上述以外删除掉它。
+* 如果一个链接以多种格式存在，请添加一个单独的链接，并注明每种格式。
+* 如果一个资源存在于Internet上的不同位置
+    * 使用最权威来源的链接(意思是原始作者的网站比编辑的网站好，比第三方网站好)。
+    * 如果它们链接到不同的版本，你认为这些版本差异很大，值得保留，那么添加一个单独的链接，并对每个版本做一个说明(参见[Issue #2353](https://github.com/EbookFoundation/free-programming-books/issues/2353)有助于格式化问题的讨论)。
+* 相较一个比较大的提交，我们更倾向于原子提交(通过添加/删除/修改进行一次提交)。在提交PR之前没有必要压缩你的提交。(我们永远不会执行这个规则，因为这只是维护人员的方便)。
+* 如果一本书比较旧，请在书名中注明出版日期。
+* 包含作者的名字或适当的名字。中文版本可以用 “等” 缩短作者列表。
+* 如果一本书还没有完成，并且仍在编写中，则需添加 “编写中” 符号，参见[下文](#in_process)所述。
+* 如果在开始下载之前需要电子邮件地址或帐户设置，请在括号中添加合适的语言描述，例如：`(*需要*电子邮件，但不是必须的)`。
+
+
+### 规定格式
+
+* 所有列表都是`.md`文件。试着学习[Markdown](https://guides.github.com/features/mastering-markdown/)语法。它很容易上手！
+* 所有的列表都以索引开始。它的作用是列出并链接所有的sections(章节/段落)或subsections(子段落/子章节)。务必遵循字母顺序排列。
+* Sections(章节/段落)使用3级标题(`###`)，subsections(子段落/子章节)使用4级标题 (`####`)。
+
+
+#### 整体思想为：   
+
+* `2` ：新添加的Section与末尾链接间必须留有`2`个空行
+* `1` ：标题和第一个链接之间必须留有`1`个空行的空行
+* `0` ：任何两个链接之间不能留有任何空行
+* `1` ：每个`.md`文件末尾必须留有`1`个空行
+
+
+#### 举例：   
+
+```
+[...]
+* [一本很有用的书](http://example.com/example.html)
+                                (空行)
+                                (空行)

+* [Another 很有用的书](http://example.com/book.html)
+* [Other 有用的书](http://example.com/other.html)
+```
+
+* 在 `]` 和 `(` 之间不要留有空格：
+
+```
+错误：* [一本很有用的书] (http://example.com/book.html)
+正确：* [一本很有用的书](http://example.com/book.html)
+```
+
+* 如果包括作者，请使用' - '(由单个空格(英文半角)包围的破折号)：

+```
+错误：* [一本很有用的书](http://example.com/book.html)- 张显宗
+正确：* [一本很有用的书](http://example.com/book.html) - 张显宗

+
+```
+错误：* [一本很有用的书](https://example.org/book.pdf)(PDF)
+正确：* [一本很有用的书](https://example.org/book.pdf) (PDF)

+
+
+Mesmo se você tem experiência com contribuições open source, existem algumas coisas que você pode errar. Por isso, assim que você submeter seu PR, ele vai ser testado por Travis-CI, e as vezes, serão encontrados problemas como espaçamento. Se você receber um botão verde, está tudo certo para uma revisão de PR. Caso contrário, clique no link do Travis para ver o problema encontrado. Arrume ele e adicione um commit ao PR.
