 ## Build instructions
-There are several software requirements for building Regamedll_CS:
-<ol>
-<li>Java Development Kit (JDK) 7+ (http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html)</li>
-<li>For Windows: Visual Studio 2015 and later</li>
-<li>For Linux: GCC/Clang/Intel C++ Compiler 15 and later</li>
-</ol>
-
 ### Checking requirements
-#### JDK version
-Windows<pre>&gt; %JAVA_HOME%\bin\javac -version
-javac 1.8.0_25
+There are several software requirements for building ReGameDLL_CS:
+
+#### Windows
+<pre>
+Visual Studio 2013 and later
 </pre>

-Linux
-<pre>$ javac -version
-javac 1.7.0_65
+#### Linux
+<pre>
+git >= 1.8.5
+cmake >= 3.10
+GCC >= 4.9.2 (Optional)
+ICC >= 15.0.1 20141023 (Optional)

 </pre>

-#### Visual Studio
-Help -> About
+### Building

-#### ICC
-<pre>$ icc --version
-icc (ICC) 15.0.1 20141023
+#### Windows
+Use `Visual Studio` to build, open `msvc/ReGameDLL.sln` and just select from the solution configurations list `Release` or `Debug`
+
+#### Linux
+
+* Optional options using `build.sh --compiler=[gcc] --jobs=[4]` (without square brackets)
+<pre>
+-c=|--compiler=[icc|gcc|clang]  - Select preferred C/C++ compiler to build
+-j=|--jobs=[N]                  - Specifies the number of jobs (commands) to run simultaneously (For faster building)
 </pre>

-### Building and run unit tests using gradle
-#### On Windows:
-<pre>gradlew --max-workers=1 clean buildRelease</pre>
-* For faster building without unit tests use this:exclamation:
-<pre>gradlew --max-workers=1 clean buildFixes</pre>
-
-#### On Linux (ICC):
-<pre>./gradlew --max-workers=1 clean buildRelease</pre>
-
-* For faster building without unit tests use this:exclamation:
-<pre>./gradlew --max-workers=1 clean buildFixes</pre>
-
-#### On Linux (Clang):
-<pre>./gradlew --max-workers=1 clean -PuseClang buildRelease</pre>
-
-* For faster building without unit tests use this:exclamation:
-<pre>./gradlew --max-workers=1 clean -PuseClang buildFixes</pre>
-
-#### On Linux (GCC):
-<pre>./gradlew --max-workers=1 clean -PuseGcc buildRelease</pre>
-
-* For faster building without unit tests use this:exclamation:
-<pre>./gradlew --max-workers=1 clean -PuseGcc buildFixes</pre>
-
-Compiled binaries will be placed in the build/binaries/ directory
-
-### Simplified building using CMake 3.1 and later
-#### On Windows:
-<pre>Open solution msvc\ReGameDLL.sln and build it</pre>
-
-#### On Linux:
-* Run script `regamedll/compile.sh`
-* Options using `regamedll/compile.sh -D[option]=[ON or OFF]` (without square brackets)
+* Optional definitions using `build.sh -D[option]=[ON or OFF]` (without square brackets)
 <pre>
 DEBUG              - Enables debugging mode
-USE_INTEL_COMPILER - Switch main compiler to ICC
-USE_CLANG_COMPILER - Switch main compiler to Clang
 USE_STATIC_LIBSTDC - Enables static linking library libstdc++
 </pre>
