-## Compatibility
-This document describes the compatibility policy of `kotlinx.coroutines` library since version 1.0.0 and semantics of compatibility-specific annotations.
-
-
-## Public API types
-`kotlinx.coroutines` public API comes in five flavours: stable, experimental, obsolete, internal and deprecated. 
-All public API except stable is marked with the corresponding annotation.
-
-### Experimental API
-Experimental API is marked with [@ExperimentalCoroutinesApi][ExperimentalCoroutinesApi] annotation.
-API is marked experimental when its design has potential open questions which may eventually lead to 
-either semantics changes of the API or its deprecation.
-
-By default, most of the new API is marked as experimental and becomes stable in one of the next major releases if no new issues arise.
-Otherwise, either semantics is fixed without changes in ABI or API goes through deprecation cycle. 
-
-When using experimental API may be dangerous:
-* You are writing a library which depends on `kotlinx.coroutines` and want to use experimental coroutines API in a stable library API.
-It may lead to undesired consequences when end users of your library update their `kotlinx.coroutines` version where experimental API
-has slightly different semantics.
-* You want to build core infrastructure of the application around experimental API. 
-
-### Flow preview API
-All [Flow]-related API is marked with [@FlowPreview][FlowPreview] annotation.
-This annotation indicates that Flow API is in preview status.
-We provide no compatibility guarantees between releases for preview features, including binary, source and semantics compatibility.
-
-When using preview API may be dangerous:
-* You are writing a library/framework and want to use [Flow] API in a stable release or in a stable API.
-* You want to use [Flow] in the core infrastructure of your application.
-* You want to use [Flow] as "write-and-forget" solution and cannot afford additional maintenance cost when 
-  it comes to `kotlinx.coroutines` updates.
-
-
-### Obsolete API
-Obsolete API is marked with [@ObsoleteCoroutinesApi][ObsoleteCoroutinesApi] annotation.
-Obsolete API is similar to experimental, but already known to have serious design flaws and its potential replacement, 
-but replacement is not yet implemented.
-
-The semantics of this API won't be changed, but it will go through a deprecation cycle as soon as the replacement is ready.
-
-### Internal API
-Internal API is marked with [@InternalCoroutinesApi][InternalCoroutinesApi] or is part of `kotlinx.coroutines.internal` package.
-This API has no guarantees on its stability, can and will be changed and/or removed in the future releases. 
-If you can't avoid using internal API, please report it to [issue tracker](https://github.com/Kotlin/kotlinx.coroutines/issues/new).
-
-### Stable API
-Stable API is guaranteed to preserve its ABI and documented semantics. If at some point unfixable design flaws will be discovered, 
-this API will go through a deprecation cycle and remain binary compatible as long as possible.
-
-### Deprecation cycle
-When some API is deprecated, it goes through multiple stages and there is at least one major release between stages.
-* Feature is deprecated with compilation warning. Most of the time, proper replacement 
-(and corresponding `replaceWith` declaration) is provided to automatically migrate deprecated usages with a help of IntelliJ IDEA.
-* Deprecation level is increased to `error` or `hidden`. It is no longer possible to compile new code against deprecated API, 
-  though it is still present in the ABI.
-* API is completely removed. While we give our best efforts not to do so and have no plans of removing any API, we still are leaving 
-this option in case of unforeseen problems such as security holes.
-
-## Using annotated API
-All API annotations are [kotlin.Experimental](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-experimental/index.html).
-It is done in order to produce compilation warning about using experimental or obsolete API.
-Warnings can be disabled either programmatically for a specific call site or globally for the whole module.
-
-### Programmatically
-For a specific call-site, warning can be disabled by using [UseExperimental](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-use-experimental/index.html) annotation:
-```kotlin
-@UseExperimental(ExperimentalCoroutinesApi::class) // Disables warning about experimental coroutines API 
-fun experimentalApiUsage() {
-    someKotlinxCoroutinesExperimentalMethod()
-}
-``` 
-
-### Gradle
-For the Gradle project, a warning can be disabled by passing a compiler flag in your `build.gradle` file:
-
-```groovy
-tasks.withType(org.jetbrains.kotlin.gradle.tasks.AbstractKotlinCompile).all {
-    kotlinOptions.freeCompilerArgs += ["-Xuse-experimental=kotlinx.coroutines.ExperimentalCoroutinesApi"]
-}
-
-```
-
-### Maven
-For the Maven project, a warning can be disabled by passing a compiler flag in your `pom.xml` file:
-```xml
-<plugin>
-    <artifactId>kotlin-maven-plugin</artifactId>
-    <groupId>org.jetbrains.kotlin</groupId>
-    ... your configuration ...
-    <configuration>
-        <args>
-            <arg>-Xuse-experimental=kotlinx.coroutines.ExperimentalCoroutinesApi</arg>
-        </args>
-    </configuration>
-</plugin>
-```
