-Minecraft Forge: Credits/Thank You
-
-Forge is a set of tools and modifications to the Minecraft base game code to assist 
-mod developers in creating new and exciting content. It has been in development for 
-several years now, but I would like to take this time thank a few people who have 
-helped it along it's way.
-
-First, the people who originally created the Forge projects way back in Minecraft 
-alpha. Eloraam of RedPower, and SpaceToad of Buildcraft, without their acceptiance 
-of me taking over the project, who knows what Minecraft modding would be today.
-
-Secondly, someone who has worked with me, and developed some of the core features
-that allow modding to be as functional, and as simple as it is, cpw. For developing
-FML, which stabelized the client and server modding ecosystem. As well as the base
-loading system that allows us to modify Minecraft's code as elegently as possible.
-
-Mezz, who has stepped up as the issue and pull request manager. Helping to keep me
-sane as well as guiding the community into creating better additions to Forge.
-
-Searge, Bspks, Fesh0r, ProfMobious, and all the rest over on the MCP team {of which 
-I am a part}. For creating some of the core tools needed to make Minecraft modding 
-both possible, and as stable as can be.
-  On that note, here is some specific information of the MCP data we use:
-    * Minecraft Coder Pack (MCP) *
-      Forge Mod Loader and Minecraft Forge have permission to distribute and automatically 
-      download components of MCP and distribute MCP data files. This permission is not 
-      transitive and others wishing to redistribute the Minecraft Forge source independently
-      should seek permission of MCP or remove the MCP data files and request their users 
-      to download MCP separately.
-      
-And lastly, the countless community members who have spent time submitting bug reports, 
-pull requests, and just helping out the community in general. Thank you.

-This is Forge Mod Loader.
-
-You can find the source code at all times at https://github.com/MinecraftForge/MinecraftForge/tree/1.12.x/src/main/java/net/minecraftforge/fml
-
-This minecraft mod is a clean open source implementation of a mod loader for minecraft servers
-and minecraft clients.
-
-The code is authored by cpw.
-
-It began by partially implementing an API defined by the client side ModLoader, authored by Risugami.
-http://www.minecraftforum.net/topic/75440-
-This support has been dropped as of Minecraft release 1.7, as Risugami no longer maintains ModLoader.
-
-It also contains suggestions and hints and generous helpings of code from LexManos, author of MinecraftForge.
-http://www.minecraftforge.net/
-
-Additionally, it contains an implementation of topological sort based on that 
-published at http://keithschwarz.com/interesting/code/?dir=topological-sort
-
-It also contains code from the Maven project for performing versioned dependency
-resolution. http://maven.apache.org/
-
-It also contains a partial repackaging of the javaxdelta library from http://sourceforge.net/projects/javaxdelta/
-with credit to it's authors.
-
-Forge Mod Loader downloads components from the Minecraft Coder Pack
-(http://mcp.ocean-labs.de/index.php/Main_Page) with kind permission from the MCP team.

+
+This mod adds a Level Of Detail (LOD) system to Minecraft.\
+This implementation renders simplified chunks outside the normal render distance\
+allowing for an increased view distance without harming performance.
+
+Or in other words: this mod lets you see farther without turning your game into a slide show.\
+If you want to see a quick demo, check out a video covering the mod here:

+
+## source code installation
+
+See the Forge Documentation online for more detailed instructions:\
+http://mcforge.readthedocs.io/en/latest/gettingstarted/
+
+1. Create a system variable called "JAVA_MC_HOME" with the location of the JDK 1.8.0_251 (This is needed for gradle to work correctly)
+2. replace JAVA_HOME with JAVA_MC_HOME in gradle.bat
+3. open a command line in the project folder
+
+**If using Ecplise:**
+1. run the command: `./gradlew geneclipseruns`
+2. run the command: `./gradlew eclipse`
+3. Make sure eclipse has the JDK 1.8.0_251 installed. (This is needed so that eclipse can run minecraft)
+4. Import the project into eclipse
+
+**If using IntelliJ:**
+1. open IDEA and import the build.gradle
+2. run the command: `./gradlew genIntellijRuns`
+3. refresh the Gradle project in IDEA if required
+
+
+## Compiling
+
+1. open a command line in the project folder
+2. run the command: `./gradlew build`
+3. the compiled jar file will be in the folder `build\libs`
+
+
+## Other commands
+
+`./gradlew --refresh-dependencies` to refresh local dependencies.
+
+`./gradlew clean` to reset everything (this does not affect your code) and then start the process again.
+
+
+## Note to self
+
+The Minecraft source code is NOT added to your workspace in an editable way. Minecraft is treated like a normal Library. Sources are there for documentation and research purposes only.
+
+Source code uses Mojang mappings.
+
+The source code can be 'created' with the `./eclipse` command and can be found in the following path:\
+`minecraft-lod-mod\build\fg_cache\mcp\ VERSION \joined\ RANDOM_STRING \patch\output.jar`
