+# TypeScript compiler (CLI)
+
+TypeScript command line compiler tool (`tcs`) does not support using of pluggable modules and transformers.
+For that reason there are other tools created that do support pluggable transformers. See [`ttypescript` compiler](#ttypescript-compiler) section.
+
+# `ttypescript` compiler
+
+The [`ttypescript` compiler](https://github.com/cevek/ttypescript) is a CLI tool that allows to use TypeScript compiler with pluggable transformers.
+To use the transformer with that tool you can configure it by updating `tsconfig.json` the following way:
+
+```json
+{
+    "compilerOptions": {
+        "plugins": [
+            {
+                "transform": "typescript-plugin-styled-components",
+                "type": "config",
+
+                // other typescript-plugin-styled-components options can be added here
+                "minify": true,
+                "ssr": true
+            }
+        ]
+    }
+}
+```
