 ## How It Works
 
-**TypeScript Node** works by registering the TypeScript compiler for the `.ts`, `.tsx` and - when `allowJs` is enabled - `.js` extensions. When node.js has a file extension registered (the `require.extensions` object), it will use the extension internally with module resolution. By default, when an extension is unknown to node.js, it will fallback to handling the file as `.js` (JavaScript).

-**P.S.** This means that if you don't register an extension, it'll be compiled as JavaScript. When `ts-node` is used with `allowJs`, JavaScript files are transpiled using the TypeScript compiler.

 ## Loading `tsconfig.json`
 
-**Typescript Node** uses `tsconfig.json` automatically, use `--no-project` to skip loading `tsconfig.json`.

 **NOTE**: You can use `ts-node` together with [tsconfig-paths](https://www.npmjs.com/package/tsconfig-paths) to load modules according to the `paths` section in `tsconfig.json`.
 
 ## Configuration Options
 
-You can set options by passing them in before the script.
-
-**Note:** These are in addition to the [node.js CLI arguments](https://nodejs.org/api/cli.html).
+You can set options by passing them before the script path, via programmatic usage or via environment variables.
 
 ```sh
-ts-node --compiler ntypescript --project src --ignoreWarnings 2304 hello-world.ts
+ts-node --compiler ntypescript --project src/tsconfig.json hello-world.ts
 ```
 
-* **--project, -P** Path to load TypeScript configuration from (JSON file, a directory containing `tsconfig.json`, or `--no-project`/`false` to disable) (also `process.env.TS_NODE_PROJECT`)
-* **--compiler, -C** Use a custom, require-able TypeScript compiler compatible with `typescript@>=1.5.0-alpha` (also `process.env.TS_NODE_COMPILER`)
-* **--ignore** Specify an array of regular expression strings for `ts-node` to skip compiling as TypeScript (defaults to `/node_modules/`, `--no-ignore`/`false` to disable) (also `process.env.TS_NODE_IGNORE`)
-* **--ignoreWarnings, -I** Set an array of TypeScript diagnostic codes to ignore (also `process.env.TS_NODE_IGNORE_WARNINGS`)
-* **--compilerOptions, -O** Set compiler options using JSON (E.g. `--compilerOptions '{"target":"es6"}'`) (also `process.env.TS_NODE_COMPILER_OPTIONS`)
-* **--type-check** Use TypeScript with type checking (also `process.env.TS_NODE_TYPE_CHECK`)
-* **--no-cache** Skip hitting the compiled JavaScript cache (also `process.env.TS_NODE_CACHE`)
-* **--cache-directory** Configure the TypeScript cache directory (also `process.env.TS_NODE_CACHE_DIRECTORY`)
+### CLI Options
+
+Support `--print`, `--eval` and `--require` from [node.js CLI options](https://nodejs.org/api/cli.html).
+
+* `--help` Prints help text
+* `--version` Prints version information
+
+### CLI and Programmatic Options
+
+_Environment variable denoted in parentheses._
+
+* `--typeCheck` Enable type checking for TypeScript (`TS_NODE_TYPE_CHECK`)
+* `--cacheDirectory` Configure the output file cache directory (`TS_NODE_CACHE_DIRECTORY`)
+* `-I, --ignore [pattern]` Override the path patterns to skip compilation (`TS_NODE_IGNORE`)
+* `-P, --project [path]` Path to TypeScript JSON project file (`TS_NODE_PROJECT`)
+* `-C, --compiler [name]` Specify a custom TypeScript compiler (`TS_NODE_COMPILER`)
+* `-D, --ignoreDiagnostics [code]` Ignore TypeScript warnings by diagnostic code (`TS_NODE_IGNORE_DIAGNOSTICS`)
+* `-O, --compilerOptions [opts]` JSON object to merge with compiler options (`TS_NODE_COMPILER_OPTIONS`)
+* `--no-cache` Disable the local TypeScript Node cache (`TS_NODE_CACHE`)
+* `--skip-project` Skip project config resolution and loading (`TS_NODE_SKIP_IGNORE`)
+* `--skip-ignore` Skip ignore checks (`TS_NODE_SKIP_PROJECT`)
+
+### Programmatic Only Options
 
-Additionally, the `transformers` option may be provided when programmatically registering `ts-node` to specify custom TypeScript transformers.
+* `transformers` An array of transformers to pass to TypeScript
+* `readFile` Custom TypeScript-compatible file reading function
+* `fileExists` Custom TypeScript-compatible file existence function
