+## SourceMap Support
+
+`c8` can handle source-maps, for remapping coverage from generated code to original source files (_useful for TypeScript, JSX, etc_).
+
+### Source map files versus inline source maps
+
+Just-in-time instrumented codebases will often insert source maps inline with the `.js` code they generate at runtime (e.g, `@babel/register` can be configured to insert a source map footer).
+
+Pre-instrumented codebases, e.g., running `tsc` to generate `.js` in a build folder, may generate either inline source maps, or a separate `.map` file stored on disk.
+
+`c8` can handle loading both types of source maps.
+
+### Exclude after remap
+
+Depending on the size and configuration of your project, it may be preferable to apply exclusion logic either before or after source-maps are used to remap compiled to original source files.
+
+`--exclude-after-remap` is used to control this behaviour.
