+# Migrating from 0.x to 1.0
+
+In Simple Scaffold v1.0, the entire codebase was overhauled, yet usage remains mostly the same
+between versions. With these notable exceptions:
+
+- Some of the argument names have changed
+- Template syntax has been improved
+- The command to run Scaffold has been simplified from `new SimpleScaffold(opts).run()` to `SimpleScaffold(opts)`, which now returns a promise that you can await to know when the process has been completed.
+
+## Argument changes
+
+- `locals` has been renamed to `data`. The appropriate command line args have been updated as
+  well to `--data` | `-d`.
+
+## Template syntax changes
+
+Simple Scaffold still uses Handlebars.js to handle template content and file names. However, helpers
+have been added to remove the need for you to pre-process the template data on simple use-cases such
+as case type manipulation (converting to camel case, snake case, etc)
+
+See the readme for the full information on how to use these helpers and which are available.

 # simple-scaffold

 Simple Scaffold allows you to create your structured files based on templates.
 
+Simply organize your commonly-created files in their original structure, and replace any variable
+values (such as component or app name) inside the paths or contents of the files with tokens to be
+populated upon scaffolding.
+
+Then, run Simple Scaffold and it will generate your files for you in the desired structure,
+with file names and contents that contain your dynamic information.
+
+It's a simple way to easily create reusable components, common class files to start writing from,
+or even entire app structures.
+
 ## Install

-## Scaffolding
-Scaffolding will replace {{vars}} in both the file name and its contents and put the transformed files
-in `<output>/<{{Name}}`.
+## Use in Node.js
 
-Your context will be pre-populated with the following:
-- `{{Name}}`: CapitalizedName of the component
-- `{{name}}`: camelCasedName of the component
-
-Any `locals` you add in the config will populate with their names wrapped in `{{` and `}}`.
-They are all stringified, so be sure to parse them accordingly by creating a script, if necessary.
-
-### Command line options
-##### `--template glob [--template glob2 [...]]` (required) (alias: -t)
-A glob pattern of template files to load.
-
-A template file may be of any type and extension, and supports [Handlebars](https://handlebarsjs.com) as a parsing engine for the file names and contents, so you may customize both with variables from your configuration.
-
-You can load more than one template list by simple adding more `--template` arguments.
-
-##### `--output path` (optional) (alias -o)
-The output directory to put the new files in. They will attempt to maintain their regular structure as they are found, if possible.
-
-Your new scaffold will be placed under a directory with the scaffold name from the argumemts.
-
-You may also pass a function to transform the output path for each file individually.
-This function takes 2 arguments: filename, and base glob path
-
-##### `--locals key=value [--locals key=value [,...]]` (optional) (alias: -l)
-Pass a KV map to the template for parsing.
-
-##### `--create-sub-folder [true|false]` (optional) (alias -S) (default: true)
-Whether to create a subfolder for the output with all the files inside, or simply dump them directly in the output folder.
-
-#####
-
-### Use in Node.js
 You can also build the scaffold yourself, if you want to create more complex arguments or scaffold groups.
-Simply pass a config object to the constructor, and invoke `run()` when you are ready to start.
+Simply pass a config object to the Scaffold function when you are ready to start.
 The config takes similar arguments to the command line:
 
-```javascript
-const SimpleScaffold = require('simple-scaffold').default
+```typescript
+import Scaffold from "simple-scaffold"
 
-const scaffold = new SimpleScaffold({
-  name: 'component',
-  templates: [path.join(__dirname, 'scaffolds', 'component')],
-  output: path.join(__dirname, 'src', 'components'),
+const config = {
+  name: "component",
+  templates: [path.join(__dirname, "scaffolds", "component")],
+  output: path.join(__dirname, "src", "components"),
   createSubFolder: true,
-  locals: {
-    property: 'value',
+  subFolderNameHelper: "upperCase"
+  data: {
+    property: "value",
+  },
+  helpers: {
+    twice: (text) => [text, text].join(" ")
   }
-}).run()
+}
+
+const scaffold = Scaffold(config)
 ```
 
-## Example Scaffold Input
+### Additional Node.js options
 
-### Input Directory structure
-```
-- project
-    - scaffold
-        - {{Name}}.js
-    - src
-        - components
-        - ...
-```
+In addition to all the options available in the command line, there are some JS-specific options
+available:
 
-#### project/scaffold/{{Name}}.js
-```js
-const React = require('react')
+1. When `output` is used in Node directly, it may also be passed a function for each input file to
+   output into a dynamic path:
 
-module.exports = class {{Name}} extends React.Component {
-  render() {
-    <div className="{{className}}">{{Name}} Component</div>
-  }
+    ```typescript
+    config.output = (fullPath, baseDir, baseName) => {
+      console.log({ fullPath, baseDir, baseName })
+      return path.resolve(baseDir, baseName)
+    }
+    ```
+
+2. You may add custom `helpers` to your scaffolds. Helpers are simple `(string) => string` functions
+   that transform your `data` variables into other values. See [Helpers](#helpers) for the list of
+   default helpers, or add your own to be loaded into the template parser.
+
+## Preparing files
+
+### Template files
+
+Put your template files anywhere, and fill them with tokens for replacement.
+
+### Variable/token replacement
+
+Scaffolding will replace `{{ varName }}` in both the file name and its contents and put the
+transformed files in the output directory.
+
+The data available for the template parser is the data you pass to the `data` config option (or
+`--data` argument in CLI).
+
+Your `data` will be pre-populated with the following:
+
+- `{{Name}}`: PascalCase of the component name
+- `{{name}}`: raw name of the component
+
+> Simple-Scaffold uses [Handlebars.js](https://handlebarsjs.com/) for outputting the file contents,
+> see their documentation for more information on syntax.
+> Any `data` you add in the config will be available for use with their names wrapped in
+> `{{` and `}}`.
+
+#### Helpers
+
+Simple-Scaffold provides some built-in text transformation filters usable by handleBars.
+
+For example, you may use `{{ snakeCase name }}` inside a template file or filename, and it will
+replace `My Name` with `my_name` when producing the final value.
+
+Here are the built-in helpers available for use:
+
+| Helper name | Example code            | Example output |
+| ----------- | ----------------------- | -------------- |
+| camelCase   | `{{ camelCase name }}`  | myName         |
+| snakeCase   | `{{ snakeCase name }}`  | my_name        |
+| startCase   | `{{ startCase name }}`  | My Name        |
+| kebabCase   | `{{ kebabCase name }}`  | my-name        |
+| hyphenCase  | `{{ hyphenCase name }}` | my-name        |
+| pascalCase  | `{{ pascalCase name }}` | MyName         |
+| upperCase   | `{{ upperCase name }}`  | MYNAME         |
+| lowerCase   | `{{ lowerCase name }}`  | myname         |
+
+> These helpers are available for any data property, not exclusive to `name`.
+
+You may also add your own custom helpers using the `helpers` options when using the JS API (rather
+than the CLI). The `helpers` option takes an object whose keys are helper names, and values are
+the transformation functions. For example, `upperCase` is implemented like so:
+
+```typescript
+config.helpers = {
+  upperCase: (text) => text.toUpperCase(),
 }
 ```
 
-### Run Example
+These helpers will also be available to you when using `subFolderNameHelper` or
+`--sub-folder-name-helper` as a possible value.
+
+## Examples
+
+### Command Example
+
 ```bash
 simple-scaffold MyComponent \
-    --template project/scaffold/**/* \
-    --output src/components \
-    --locals 'className=my-component`
+    -t project/scaffold/**/* \
+    -o src/components \
+    -d '{"className": "myClassName"}'
+    MyComponent

+## Contributing
+
+I welcome any issues or pull requests on GitHub. If you find a bug, or would like a new feature,
+don't hesitate to open an appropriate issue and I will do my best to reply promptly.
+
+If you are a developer and want to contribute code, here are some starting tips:
+
+1. Fork this repository
+2. Run `yarn install`
+3. Run `yarn dev` to start file watch mode
+4. Make any changes you would like
+5. Create tests for your changes
+6. Update the relevant documentation (readme, code comments, type comments)
+7. Create a PR on upstream
+
+Some tips on getting around the code:
+
+- Use `yarn dev` for development - it runs TypeScript compile in watch mode, allowing you to make
+  changes and immediately be able to try them using `yarn cmd`.
+- Use `yarn build` to build the output
+- Use `yarn test` to run tests
+- Use `yarn cmd` to use the CLI feature of Simple Scaffold from within the root directory,
+  enabling you to test different behaviors. See `yarn cmd -h` for more information.
+
+  > This requires an updated build, and does not trigger one itself. Either use `yarn dev` to watch
+  > for changes and build, or `yarn build` before running this, or use `yarn build-cmd` instead,
+  > which triggers a build right before running the command with the rest of the given arguments.

+ * Create a scaffold using given `options`.
+ *
+ * #### Create files
+ * To create a file structure to output, use any directory and file structure you would like.
+ * Inside folder names, file names or file contents, you may place `{{ var }}` where `var` is either
+ * `name` which is the scaffold name you provided or one of the keys you provided in the `data` option.
+ *
+ * The contents and names will be replaced with the transformed values so you can use your original structure as a
+ * boilerplate for other projects, components, modules, or even single files.
+ *
+ * #### Helpers
+ * Helpers are functions you can use to transform your `{{ var }}` contents into other values without having to
+ * pre-define the data and use a duplicated key. Common cases are transforming name-case format
+ * (e.g. `MyName` → `my_name`), so these have been provided as defaults:
+ *
+ * | Helper name | Example code            | Example output |
+ * | ----------- | ----------------------- | -------------- |
