 ### Compile from command line on Windows
 1. If you installed Qt with the web installer, there should be a shortcut called `Qt 5.4 for Desktop (MinGW 4.9 32-bit)` in the Start menu on Windows 7 and 10. Best way to find it is to search for it. Do note you cannot just use cmd.exe, you have to use the shortcut, otherwise the proper MinGW software will not be on the PATH.
-2. Once that is open, change into your user directory, and clone MultiMC by doing `git clone --recursive https://github.com/MultiMC/Launcher.git`, and change directory to the folder you cloned to.
+2. Once that is open, change into your user directory, and clone MultiMC by doing `git clone --recursive https://github.com/MultiMC/MultiMC5.git`, and change directory to the folder you cloned to.
 3. Make a build directory, and change directory to the directory and do `cmake -G "MinGW Makefiles" -DCMAKE_INSTALL_PREFIX=C:\Path\that\makes\sense\for\you`. By default, it will install to C:\Program Files (x86), which you might not want, if you want a local installation. If you want to install it to that directory, make sure to run the command window as administrator.
 3. Do `mingw32-make -jX`, where X is the number of cores your CPU has plus one.
 4. Now to wait for it to compile. This could take some time. Hopefully it compiles properly.
 5. Run the command `mingw32-make install`, and it should install MultiMC, to whatever the `-DCMAKE_INSTALL_PREFIX` was.
 6. In most cases, whenever compiling, the OpenSSL dll's aren't put into the directory to where MultiMC installs, meaning you cannot log in. The best way to fix this is just to do `copy C:\OpenSSL-Win32\*.dll C:\Where\you\installed\MultiMC\to`. This should copy the required OpenSSL dll's to log in.

 MultiMC 5
 =========
 
-MultiMC is a custom launcher for Minecraft that focuses on predictability, long term stability and simplicity.
+MultiMC is a custom launcher for Minecraft that allows you to easily manage multiple installations of Minecraft at once. It also allows you to easily install and remove mods by simply dragging and dropping. Here are the current [features](https://github.com/MultiMC/MultiMC5/wiki#features) of MultiMC.
+
 
 ## Development
-If you want to contribute, talk to us on [Discord](https://discord.gg/multimc) first.
+The project uses C++ and Qt5 as the language and base framework. This might seem odd in the Minecraft community, but allows using 25MB of RAM, where other tools use an excessive amount of resources for no reason.
 
-While blindly submitting PRs is definitely possible, they're not necessarily going to get accepted.
+We can do more, with less, on worse hardware and leave more resources for the game while keeping the launcher running and providing extra features.
 
-We aren't looking for flashy features, but expanding upon the existing feature set without distruption or endangering future viability of the project is OK.
+If you want to contribute, either talk to us on [Discord](https://discord.gg/0k2zsXGNHs0fE4Wm), [IRC](http://webchat.esper.net/?nick=&channels=MultiMC)(esper.net/#MultiMC) or pick up some item from [workflowy](https://workflowy.com/s/2EyDMcp7CU) - there are many.
 
 ### Building
 If you want to build MultiMC yourself, check [BUILD.md](BUILD.md) for build instructions.
 
-### Code formatting
+The ci server is running at [ci.multimc.org](http://ci.multimc.org), where you can watch the builds happen in (or very close to) real time. It can also serve as a nice reference on how to set up the build environment on your end.
-Just follow the existing formatting.
 
-In general, in order of importance:
+According to travis.ci, the builds are currently [![Build Status](https://travis-ci.org/MultiMC/MultiMC5.svg?branch=develop)](https://travis-ci.org/MultiMC/MultiMC5)
-* Make sure your IDE is not messing up line endings or whitespace and avoid using linters.
+
-* Prefer readability over dogma.
+### Code formatting
-* Keep to the existing formatting.
+We use [Clang Format](http://clang.llvm.org/docs/ClangFormat.html) to format the project. We highly recommend setting it up so the project stays well formatted.
-* Indent with 4 space unless it's in a submodule.
-* Keep lists (of arguments, parameters, initializers...) as lists, not paragraphs. It should either read from top to bottom, or left to right. Not both.
 
 
 ## Translations
-Translations can be done [on crowdin](https://translate.multimc.org). Please avoid making direct pull requests to the translations repository.
+Translations can be done either directly in the [translations repository](https://github.com/MultiMC/MultiMC5). For more details, see: [Translating-MultiMC](https://github.com/MultiMC/MultiMC5/wiki/Translating-MultiMC).
 
-## Forking/Redistributing/Custom builds policy
+## Forking/Redistributing
 We keep MultiMC open source because we think it's important to be able to see the source code for a project like this, and we do so using the Apache license.
 
-Part of the reason for using the Apache license is that we don't want people using the "MultiMC" name when redistributing the project. This means people must take the time to go through the source code and remove all references to "MultiMC", including but not limited to the project icon and the title of windows, (no *MultiMC-fork* in the title).

 Apache covers reasonable use for the name - a mention of the project's origins in the About dialog and the license is acceptable. However, it should be abundantly clear that the project is a fork *without* implying that you have our blessing.
