-Image loading based on `Coil` library.
+Image loading based on [Coil](https://github.com/coil-kt/coil/) library.
+
+There are 3 factory methods to obtain `CoilImagesPlugin`:
 
 ```kotlin

 :::warning
 In order to use the `CoilImagesPlugin.create(Context)` factory method your
-app must have **explicit** dependency on `coil` library
+app must have **explicit** dependency on `coil` (`io.coil-kt:coil`) library. This artifact
+relies on `io.coil-kt:coil-base` as per [Coil documentation](https://coil-kt.github.io/coil/getting_started/#artifacts)

+val imageLoader: ImageLoader
+  get() = ImageLoader.Builder(context)

+Finally, use as a regular plugin:
+
+```kotlin
+val markwon = Markwon.builder(context)
+  .usePlugin(coilPlugin)
+  .build()
