+# Introduction
+
+An advanced mechanism for formatting type errors and inspecting missing
+implicits has been introduced in Scala 2.13.6.
+It is based on the compiler plugin [splain](https://github.com/tek/splain).
+
+This tool abstracts several classes of compiler errors with simple data types
+that can be processed by a few built-in routines as well as
+[user-provided analyzer plugins](/overviews/plugins/index.html).
+
+The most significant feature is the illustration of chains of implicit instances
+that allows a user to determine the root cause of an implicit error:
+
+![implicits](/resources/img/implicits-circe.jpg)
+
+# Basic Configuration
+
+* `-Vimplicits` enables printing of implicit chains
+* `-Vtype-diffs` enables colored diffs for found/required errors
+
+## Additional Configuration
+
+`-Vimplicits-verbose-tree` shows the implicits between the error site and the
+root cause, see [#implicit-resolution-chains].
+
+`-Vimplicits-max-refined` reduces the verbosity of refined types, see
+[#truncating-refined-types].
+
+# Features
+
+The error formatting engine provides the following enhancements:
+
+# Infix Types
+
+Instead of `shapeless.::[A, HNil]`, prints `A :: HNil`.
+
+# Found/Required Types
+
+Rather than printing up to four types, only the dealiased types are shown as a colored diff:
+
+![foundreq](/resources/img/foundreq.jpg)
+
+# Implicit Resolution Chains
+
+When an implicit is not found, only the outermost error at the invocation point
+is printed by the regular error reporter. This can be expanded with the
+compiler flag `-Xlog-implicits`, but that also shows all invalid implicits for
+parameters that have been resolved successfully.
+
+This feature prints a compact list of all involved implicits:
+
+![compact](/resources/img/implicits-compact.jpg)
+
+Here, `!I` stands for *could not find implicit value*, the name of the implicit
+parameter is in yellow, and its type in green.
+
+If the parameter `-Vimplicits-verbose-tree` is given, all intermediate implicits will be
+printed, potentially spanning tens of lines.
+An example of this is the circe error at the top of the page.
+
+For comparison, this is the regular compiler output for this case:
+
+```
+[error] /path/Example.scala:20:5: could not find implicit value for parameter a: io.circe.Decoder[A] 
+[error]   A.fun
+[error]     ^
+```
+
+# Infix Type and Type Argument Line Breaking
+
+Types longer than 79 characters will be split into multiple lines:
+
+```
+implicit error;
+!I e: String
+f invalid because
+!I impPar4: List[
+  (
+    VeryLongTypeName ::::
+    VeryLongTypeName ::::
+    VeryLongTypeName ::::
+    VeryLongTypeName
+  )
+  ::::
+  (Short :::: Short) ::::
+  (
+    VeryLongTypeName ::::
+    VeryLongTypeName ::::
+    VeryLongTypeName ::::
+    VeryLongTypeName
+  )
+  ::::
+  VeryLongTypeName ::::
+  VeryLongTypeName ::::
+  VeryLongTypeName ::::
+  VeryLongTypeName
+]
+```
+
+# Truncating Refined Types
+
+A type of the shape `T { type A = X; type B = Y }` will be displayed as `T
+{...}` if the option `-Vimplicits-max-refined` is set to a value `/= 0` and
+the refinement's length is greater than the value.
