+Source installation information for modders
+-------------------------------------------
+This code follows the Minecraft Forge installation methodology. It will apply
+some small patches to the vanilla MCP source code, giving you and it access 
+to some of the data and functions you need to build a successful mod.
+
+Note also that the patches are built against "unrenamed" MCP source code (aka
+srgnames) - this means that you will not be able to read them directly against
+normal code.
+
+Source pack installation information:
+
+Standalone source installation
+==============================
+
+See the Forge Documentation online for more detailed instructions:
+http://mcforge.readthedocs.io/en/latest/gettingstarted/
+
+Step 1: Open your command-line and browse to the folder where you extracted the zip file.
+
+Step 2: You're left with a choice.
+If you prefer to use Eclipse:
+1. Run the following command: "gradlew genEclipseRuns" (./gradlew genEclipseRuns if you are on Mac/Linux)
+2. Open Eclipse, Import > Existing Gradle Project > Select Folder 
+   or run "gradlew eclipse" to generate the project.
+(Current Issue)
+4. Open Project > Run/Debug Settings > Edit runClient and runServer > Environment
+5. Edit MOD_CLASSES to show [modid]%%[Path]; 2 times rather then the generated 4.
+
+If you prefer to use IntelliJ:
+1. Open IDEA, and import project.
+2. Select your build.gradle file and have it import.
+3. Run the following command: "gradlew genIntellijRuns" (./gradlew genIntellijRuns if you are on Mac/Linux)
+4. Refresh the Gradle Project in IDEA if required.
+
+If at any point you are missing libraries in your IDE, or you've run into problems you can run "gradlew --refresh-dependencies" to refresh the local cache. "gradlew clean" to reset everything {this does not affect your code} and then start the processs again.
+
+Should it still not work, 
+Refer to #ForgeGradle on EsperNet for more information about the gradle environment.
+or the Forge Project Discord discord.gg/UvedJ9m
+
+Forge source installation
+=========================
+MinecraftForge ships with this code and installs it as part of the forge
+installation process, no further action is required on your part.
