+Want to contribute? Great! First, read this page (including the small print at the end).
+
+### Before you contribute
+Before we can use your code, you must sign the
+[Google Individual Contributor License Agreement]
+(https://cla.developers.google.com/about/google-individual)
+(CLA), which you can do online. The CLA is necessary mainly because you own the
+copyright to your changes, even after your contribution becomes part of our
+codebase, so we need your permission to use and distribute your code. We also
+need to be sure of various other things—for instance that you'll tell us if you
+know that your code infringes on other people's patents. You don't have to sign
+the CLA until after you've submitted your code for review and a member has
+approved it, but you must do it before we can put your code into our codebase.
+Before you start working on a larger contribution, you should get in touch with
+us first through the issue tracker with your idea so that we can help out and
+possibly guide you. Coordinating up front makes it much easier to avoid
+frustration later on.
+
+### Code reviews
+All submissions, including submissions by project members, require review. We
+use Github pull requests for this purpose.
+
+### The small print
+Contributions made by corporations are covered by a different agreement than
+the one above, the

+# rollup-plugin-off-main-thread
+
+Use Rollup with workers and ES6 modules _today_.
+
+```
+$ npm install --save @surma/rollup-plugin-off-main-thread
+```
+
+Workers are JavaScript’s version of threads. [Workers are important to use][when workers] as the main thread is already overloaded, especially on slower or older devices.
+
+This plugin takes care of shimming module support in workers and allows you to use `new Worker()`.
+
+OMT is the result of merging loadz0r and workz0r.
+
+## Usage
+
+I set up [a gist] to show a full setup with OMT.
+
+### Config
+
+```js
+// rollup.config.js
+import OMT from "@surma/rollup-plugin-off-main-thread";
+
+export default {
+  input: ["src/main.js"],
+  output: {
+    dir: "dist",
+    // You _must_ use either “amd” or “esm” as your format.
+    // But note that only very few browsers have native support for
+    // modules in workers.
+    format: "amd"
+  },
+  plugins: [OMT()]
+};
+```
+
+### Auto bundling
+
+In your project's code use a module-relative path via `new URL` to include a Worker:
+
+```js
+const worker = new Worker(new URL("worker.js", import.meta.url), {
+  type: "module"
+});
+```
+
+This will just work.
+
+If required, the plugin also supports plain literal paths:
+
+```js
+const worker = new Worker("./worker.js", { type: "module" });
+```
+
+However, those are less portable: in Rollup they would result in module-relative
+path, but if used directly in the browser, they'll be relative to the document
+URL instead.
+
+Hence, they're deprecated and `new URL` pattern is encouraged instead for portability.
+
+### Importing workers as URLs
+
+If your worker constructor doesn't match `workerRegexp` (see options below), you might find it easier to import the worker as a URL. In your project's code:
+
+```js
+import workerURL from "omt:./worker.js";
+import paintWorkletURL from "omt:./paint-worklet.js";
+
+const worker = new Worker(workerURL, { name: "main-worker" });
+CSS.paintWorklet.addModule(paintWorkletURL);
+```
+
+`./worker.js` and `./paint-worklet.js` will be added to the output as chunks.
+
+## Options
+
+```js
+{
+  // ...
+  plugins: [OMT(options)];
+}
+```
+
+- `loader`: A string containing the EJS template for the amd loader. If `undefined`, OMT will use `loader.ejs`.
+- `useEval`: Use `fetch()` + `eval()` to load dependencies instead of `<script>` tags and `importScripts()`. _This is not CSP compliant, but is required if you want to use dynamic imports in ServiceWorker_.
+- `workerRegexp`: A RegExp to find `new Workers()` calls. The second capture group _must_ capture the provided file name without the quotes.
+- `amdFunctionName`: Function name to use instead of AMD’s `define`.
+- `prependLoader`: A function that determines whether the loader code should be prepended to a certain chunk. Should return true if the load is suppsoed to be prepended.
+- `urlLoaderScheme`: Scheme to use when importing workers as URLs. If `undefined`, OMT will use `"omt"`.
