 # SDI
 
+It is simple (in comparison with other systems) DI, which aim to be compatible and predictable.
+
+## Availability platforms
+
+* [x] JVM
+* [ ] JS
+* [ ] Native
+
+## Required environment
+
+To use this library you will need two things:
+
+* Json serializer
+* Json config
+
+Unfortunately, currently not supported other formats (due to
+[issue in Kotlinx.serialization](https://github.com/Kotlin/kotlinx.serialization/issues/615))
+
+## Rules
+
+Full examples of usage you can find in [tests](src/commonTest/kotlin/com/insanusmokrassar/sdi). In two words, there are
+a few rules for constructing of config:
+
+* Config root is an Json Object
+* Config root names will be used as dependency names
+* In the config dependency names can be used everywhere
+* In places, where dependency will be injected, must be used `@ContextualSerializer` annotation or `@Serializer(ContextSerializer::class)`
