+- **To compile with `tsc`** — Use [ts-patch](https://github.com/nonara/ts-patch)

+    "compilerOptions" { /* ... */ }
+  }
+  ```

-## `ts-node` & TS Compiler API Usage
-
-### Note
-Most people using `ts-node` can achieve what they want without the transformer, by using [tsconfig-paths](https://github.com/dividab/tsconfig-paths#readme]) (ie. `ts-node -r tsconfig-paths`)
-
-### Others
-
-If you'd still like to use the transformer, it is now possible to do so programmatically, with or without a `Program` instance. This can be done via `ts-node` or the compiler API using `ts.transform()`.
-
-Here is an example of how to register `ts-node` with the transformer:
-
-```ts
-import transformer, { TsTransformPathsConfig } from 'typescript-transform-paths';
-import { register } from 'ts-node';
-import ts from 'typescript';
-
-const pluginConfig: TsTransformPathsConfig = {
-  useRootDirs: false
-};
-
-// Use this code if using transpileOnly
-register({
-  transpileOnly: true,
-  transformers: {
-    before: [ transformer(/* Program */ undefined, pluginConfig) ]
-  }
-});
-
-// Use this if not using transpileOnly
-register({
-  transformers: (program: ts.Program) => { before: [ transformer(program, pluginConfig) ] }
-});
-```
-
-For TS compiler API usage example, have a look at the logic in [specific.test.ts](https://github.com/LeDDGroup/typescript-transform-paths/blob/master/test/tests/transformer/specific.test.ts) for `manual` mode.
