-## Kotlin Multiplatform capabilities
-
-Support for multiplatform programming is one of Kotlin’s key benefits. It reduces time spent writing and maintaining the same code for [different platforms](https://kotlinlang.org/docs/reference/mpp-supported-platforms.html) while retaining the flexibility and benefits of native programming.

 ## Build environment requirements
 
 In order to build Kotlin distribution you need to have:
 
-- JDK 1.6, 1.7, 1.8 and 9
+- Apache Ant 1.9.4 and higher
+- JDK 1.6, 1.7 and 1.8
 - Setup environment variables as following:
 
         JAVA_HOME="path to JDK 1.8"
         JDK_16="path to JDK 1.6"
         JDK_17="path to JDK 1.7"
         JDK_18="path to JDK 1.8"
-        JDK_9="path to JDK 9"
 
-For local development, if you're not working on bytecode generation or the standard library, it's OK to have only JDK 1.8 and JDK 9 installed, and to point `JDK_16` and `JDK_17` environment variables to your JDK 1.8 installation.
+For local development, if you're not working on bytecode generation or the standard library, it's OK to have only JDK 8 installed, and to point all of the environment variables mentioned above to your JDK 8 installation.
 
-You also can use [Gradle properties](https://docs.gradle.org/current/userguide/build_environment.html#sec:gradle_configuration_properties) to setup `JDK_*` variables.
+You also can use [Gradle properties](https://docs.gradle.org/current/userguide/build_environment.html#sec:gradle_properties_and_system_properties) to setup JDK_* variables.
 
-Note: The JDK 6 for MacOS is not available on Oracle's site. You can install it by
-
-```bash
-$ brew tap caskroom/versions
-$ brew cask install java6
-```
-
-On Windows you might need to add long paths setting to the repo:
-
-    git config core.longpaths true 
+> Note: The JDK 6 for MacOS is not available on Oracle's site. You can [download it here](https://support.apple.com/kb/DL1572). 
 
 ## Building
 
-The project is built with Gradle. Run Gradle to build the project and to run the tests 
-using the following command on Unix/macOS:
+To build this project, first time you try to build you need to run this:
 
-    ./gradlew <tasks-and-options>
-    
-or the following command on Windows:
+    ant -f update_dependencies.xml
 
-    gradlew <tasks-and-options>
-
-On the first project configuration gradle will download and setup the dependencies on
+which will setup the dependencies on
 
 * `intellij-core` is a part of command line compiler and contains only necessary APIs.
 * `idea-full` is a full blown IntelliJ IDEA Community Edition to be used in the plugin module.
 
-These dependencies are quite large, so depending on the quality of your internet connection 
-you might face timeouts getting them. In this case you can increase timeout by specifying the following 
-command line parameters on the first run: 
+Then, you may run Gradle to build the project and run tests, using:
+
+    ./gradlew <tasks-and-options>
     
-    ./gradlew -Dhttp.socketTimeout=60000 -Dhttp.connectionTimeout=60000
+command on Unix/macOS, or
+
+    gradlew <tasks-and-options>
+    
+on Windows.
 
 ## Important gradle tasks
 
 - `clean` - clean build results
 - `dist` - assembles the compiler distribution into `dist/kotlinc/` folder
-- `ideaPlugin` - assembles the Kotlin IDEA plugin distribution into `dist/artifacts/ideaPlugin/Kotlin/` folder
+- `ideaPlugin` - assembles the Kotlin IDEA plugin distribution into `dist/artifacts/Kotlin` folder
 - `install` - build and install all public artifacts into local maven repository
 - `runIde` - build IDEA plugin and run IDEA with it
 - `coreLibsTest` - build and run stdlib, reflect and kotlin-test tests
-- `gradlePluginTest` - build and run gradle plugin tests
+- `gradlePluginsTest` - build and run gradle plugin tests
 - `compilerTest` - build and run all compiler tests
 - `ideaPluginTest` - build and run all IDEA plugin tests
 
-To reproduce TeamCity build use `-Pteamcity=true` flag. Local builds don't run proguard and have jar compression disabled by default.
+**OPTIONAL:** Some artifacts, mainly Maven plugin ones, are built separately by Maven: go into `libraries` directory after building the compiler and run:
+
+    mvn install
 
-**OPTIONAL:** Some artifacts, mainly Maven plugin ones, are built separately with Maven.

+## Working with the project in IntelliJ IDEA
 
-### Building for different versions of IntelliJ IDEA and Android Studio
+Working with the Kotlin project requires IntelliJ IDEA 2017.3. You can download an Early Access Preview version of IntelliJ IDEA 2017.3 [here](https://www.jetbrains.com/idea/nextversion/).
 
-Kotlin plugin is intended to work with several recent versions of IntelliJ IDEA and Android Studio. Each platform is allowed to have a different set of features and might provide a slightly different API. Instead of using several parallel Git branches, project stores everything in a single branch, but files may have counterparts with version extensions (\*.as32, \*.172, \*.181). The primary file is expected to be replaced with its counterpart when targeting non-default platform.
-
-More detailed description of this scheme can be found at https://github.com/JetBrains/bunches/blob/master/ReadMe.md.
-
-Usually, there's no need to care about multiple platforms as all features are enabled everywhere by default. Additional counterparts should be created if there's an expected difference in behavior or an incompatible API usage is required **and** there's no reasonable workaround to save source compatibility. Kotlin plugin contains a pre-commit check that shows a warning if a file has been updated without its counterparts.
-
-Development for some particular platform is possible after 'switching' that can be done with [Bunch Tool](https://github.com/JetBrains/bunches/releases) from the command line.
-
-```sh
-cd kotlin-project-dir
-
-# switching to IntelliJ Idea 2019.1
-bunch switch 191
-```
-
-## <a name="working-in-idea"></a> Working with the project in IntelliJ IDEA
-
-Working with the Kotlin project requires at least IntelliJ IDEA 2019.1. You can download IntelliJ IDEA 2019.1 [here](https://www.jetbrains.com/idea/download).
-
-After cloning the project, to import the project in IntelliJ choose the project directory in the Open project dialog. Then, after project opened, select 
-`File` -> `New` -> `Module from Existing Sources...` in the menu, and select `build.gradle.kts` file in the project's root folder.

+`File` -> `New...` -> `Module from Existing Sources` in the menu, and select `build.gradle.kts` file in the project's root folder.
 
 In the import dialog, select `use default gradle wrapper`.
 
-To be able to run tests from IntelliJ easily, check `Delegate IDE build/run actions to Gradle` and choose `Gradle Test Runner` in the Gradle runner settings after importing the project.
+To be able to run tests from IntelliJ easily, check `Delegate IDE build/run actions to Gradle` in the Gradle runner settings.
 
-At this time, you can use the latest released `1.3.x` version of the Kotlin plugin for working with the code. To make sure you have the latest version installed, use `Tools` -> `Kotlin` -> `Configure Kotlin Plugin Updates`.
+At this time, you can use the latest released 1.1.x version of the Kotlin plugin for working with the code. To make sure you have the latest version installed, use Tools | Kotlin | Configure Kotlin Plugin Updates and press "Check for updates now".

-* `VCS` -> `Git` -> `Pull`
-* Run the `IDEA` run configuration in the project
-* A child IntelliJ IDEA with the Kotlin plugin will then startup
-
-### Including into composite build
-
-To include kotlin compiler into [composite build](https://docs.gradle.org/current/userguide/composite_builds.html) you need to define `dependencySubstitution` for `kotlin-compiler` module in `settings.gradle.kts`
-
-```Kotlin
-includeBuild("/path/to/kotlin") {
-    dependencySubstitution {
-        substitute(module("org.jetbrains.kotlin:kotlin-compiler"))
-            .with(project(":include:kotlin-compiler"))
-    }
-}
-```
-
-or in `settings.gradle`
-
-```Groovy
-includeBuild('/path/to/kotlin') {
-    dependencySubstitution {
-        substitute module('org.jetbrains.kotlin:kotlin-compiler') with project(':include:kotlin-compiler')
-    }
-}
-```

 # Contributing
 
-Please be sure to review Kotlin's [contributing guidelines](docs/contributing.md) to learn how to help the project.
+We love contributions! There's [lots to do on Kotlin](https://youtrack.jetbrains.com/issues/KT) and on the
+[standard library](https://youtrack.jetbrains.com/issues/KT?q=%23Kotlin%20%23Unresolved%20and%20(links:%20KT-2554,%20KT-4089%20or%20%23Libraries)) so why not chat with us
+about what you're interested in doing? Please join the #kontributors channel in [our Slack chat](http://slack.kotlinlang.org/)
+and let us know about your plans.
+
+If you want to find some issues to start off with, try [this query](https://youtrack.jetbrains.com/issues/KT?q=tag:%20%7BUp%20For%20Grabs%7D%20%23Unresolved) which should find all Kotlin issues that marked as "up-for-grabs".
+
+Currently only committers can assign issues to themselves so just add a comment if you're starting work on it.
+
+A nice gentle way to contribute would be to review the [standard library docs](https://kotlinlang.org/api/latest/jvm/stdlib/index.html)
+and find classes or functions which are not documented very well and submit a patch.
+
+In particular it'd be great if all functions included a nice example of how to use it such as for the
+[`hashMapOf()`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/hash-map-of.html) function.
+This is implemented using the [`@sample`](https://github.com/JetBrains/kotlin/blob/1.1.0/libraries/stdlib/src/kotlin/collections/Maps.kt#L91)
+macro to include code from a test function. The benefits of this approach are twofold; First, the API's documentation is improved via beneficial examples that help new users and second, the code coverage is increased.
+
+Also the [JavaScript translation](https://github.com/JetBrains/kotlin/blob/master/js/ReadMe.md) could really use your help. See the [JavaScript contribution section](https://github.com/JetBrains/kotlin/blob/master/js/ReadMe.md) for more details.
+
+Some of the code in the standard library is created by generating code from templates. See the [README](libraries/stdlib/ReadMe.md) in the stdlib section for how run the code generator. The existing templates can be used as examples for creating new ones.
+
+## Submitting patches
+
+The best way to submit a patch is to [fork the project on github](https://help.github.com/articles/fork-a-repo/) then send us a
+[pull request](https://help.github.com/articles/creating-a-pull-request/) via [github](https://github.com).
+
+If you create your own fork, it might help to enable rebase by default
+when you pull by executing
+``` bash
+git config --global pull.rebase true
+```
+This will avoid your local repo having too many merge commits
+which will help keep your pull request simple and easy to apply.
