-# Compilers' Version and Parameters
-
-Hydro使用 [HydroJudger](https://github.com/hydro-dev/HydroJudger) 进行评测，以docker镜像的形式安装至评测机。  
-所使用的编译器均为创建镜像时 [debian testing](https://wiki.debian.org/DebianTesting) 分支的最新版。编译参数如下：  
-
-- Free Pascal `fpc -O2 -o/out/foo /in/foo.pas`  
-- C `gcc -O2 -Wall -std=c99 -o /out/foo /in/foo.c -lm`  
-- C++ `g++ -O2 -Wall -std=c++11 -o /out/foo /in/foo.cc -lm`  
-- Java `javac Main.java`  
-- Python `python foo.py`  
-- Python 3 `python3 foo.py`  
-- PHP `php foo.php`  
-- Rust `rustc -O -o /out/foo /in/foo.rs`  
-- Haskell `ghc -O -outputdir /tmp -o /out/foo /in/foo.hs`  
-
-# Limitations
-
-Hydro 评测机使用进程的CPU时间计算时间消耗，时间的限定为题目中评测点所指定的时间。  
-Hydro 评测机使用进程虚拟内存与物理内存总和计算内存空间消耗。内存空间默认限定为256MiB，题目中特别指明的，限定为题目中评测点所指定的内存空间。  
-
-# IO
-
-若无特殊说明，Hydro 使用标准输入输出（控制台输入输出，屏幕输入输出，STD I/O）。  
-

-# Compile Error
-
-可能有以下情况：
-
-- 递交时选错了编程语言  
-- Java 的主类名没有使用 "Main"  
-- 对于 C/C++：见下  
-- 一般性的编译错误  
-
-<blockquote class="warn">
-    <p>对 C/C++ 选手的特别提醒：</p>
-    <ul>
-        <li>1. __int64 在 GNU C++ 中应写成 long long 类型</li>
-        <li>2. main() 返回值必须定义为 int ，而不是 void</li>
-        <li>3. for 语句中的指标变量 i 将会在如"for (int i = 0...) {...}"语句之后变为无效</li>
-        <li>4. itoa 不是一个通用 ANSI 函数（标准 C/C++ 中无此函数）</li>
-        <li>5. printf 中使用 %lf 格式是不正确的</li>
-    </ul>

-# Training
-
-我们精心挑选了一些题目组成了训练计划。单击导航栏的“训练”即可进入！
-
-# Contest
-
-按照赛制不同，有不同的递交、排名规则。  
-OI 赛制所有题目均以最后一次递交为准，特别地，请避免编译错误。  
-OI 赛制排名规则为：总分高的排在前面，总分相等则排名相同。  
-ACM/ICPC 赛制所有题目递交后立即评测，以是否通过为准。  
-ACM/ICPC 赛制排名规则为：通过题目数多的排在前面，通过题目数相同的做题耗时（含罚时）少的排在前。  
-时间与空间限制以题目说明为准，默认限制参见[Limitations](#Limits)。  
-
-# Accepted Ratio
-
-通过率的影响极其恶劣，Hydro 不提供也不承认通过率。  
-
-# RP
-
-Hydro RP 分为固定 RP 与浮动 RP ，固定 RP 可由活动、比赛等的奖励获得，浮动 RP 由一般性通过题目获得。  
-浮动 RP 是一个动态的数值，每个用户在每道题上获得的 RP 都不一样，并且未来也不固定（即浮动之意）。  
-
-:::note 每道题的浮动 RP 由该题通过总人数与该用户通过此题的名次计算得来。:::
-
-# Dataset Format
-
-TODO
-
-# Forgot Password and/or Username
-
-如果您无法登录，请仔细想想，是不是用户名记错了。比如，自己原本想要注册的用户名已经被注册，所以使用了一个带有前和/或后缀的用户名。  
-如果您确信您的账号被盗或者忘记了账号和/或密码，请及时[{{ _('Reset Password or Find Username') }}](/lostpass)。
