-## Example: html-minifier
+## Examples
 
-Let's walk through what it takes to create a simple builder that takes in a HTML source file and yields a minified HTML static file as its build output.
+Check out our [Node.js Runtime](https://github.com/zeit/now/tree/master/packages/now-node), [Go Runtime](https://github.com/zeit/now/tree/master/packages/now-go), [Python Runtime](https://github.com/zeit/now/tree/master/packages/now-python) or [Ruby Runtime](https://github.com/zeit/now/tree/master/packages/now-ruby) for examples of how to build one.
-
-While this is a very simple builder, the approach demonstrated here can be used to return anything: one or more static files and/or one or more lambdas.
-
-## Setting up the module
-
-### Defining the analyze step
-
-The `analyze` hook is optional. Its goal is to give the developer a tool to avoid wasting time _re-computing a build_ that has already occurred.
-
-The return value of `analyze` is a _fingerprint_: a simple string that uniquely identifies the build process.
-
-If `analyze` is not specified, its behavior is to use as the fingerprint the combined checksums of **all the files in the same directory level as the entrypoint**. This is a default that errs on making sure that we re-execute builds when files _other than the entrypoint_ (like dependencies, manifest files, etc) have changed.
-
-For our `html-minify` example, we know that HTML files don't have dependencies. Therefore, our analyze step can just return the `digest` of the entrypoint.
-
-Our `index.js` file looks as follows:
-
-```js
-exports.analyze = function({ files, entrypoint }) {
-  return files[entrypoint].digest
-}
-```
-
-This means that we will only re-minify and re-create the build output _only if the file contents (and therefore its digest) change._
-
-### Defining the build step
-
-Your module will need some utilities to manipulate the data structures we pass you, create new ones and alter the filesystem.
-
-To that end, we expose our API as part of a `@now/build-utils` package. This package is always loaded on your behalf, so make sure it's only included as `peerDependencies` in your `package.json`.
-
-Builders can include dependencies of their liking:
-
-```js
-const htmlMinifier = require('html-minifier')
-
-exports.version = 2
-
-exports.analyze = ({ files, entrypoint }) => files[entrypoint].digest
-
-exports.build = async ({ files, entrypoint, config }) => {
-  const stream = files[entrypoint].toStream()
-  const options = Object.assign({}, config || {})
-  const { data } = await FileBlob.fromStream({ stream })
-  const content = data.toString()
-  const minified = htmlMinifier(content, options)
-  const result = new FileBlob({ data: minified })
-
-  return {
-    output: {
-      [entrypoint]: result
-    },
-    watch: [],
-    routes: {}
-  }
-}
-```
-
-### Defining a `prepareCache` step
-
-If our builder had performed work that could be re-used in the next build invocation, we could define a `prepareCache` step.
-
-In this case, there are not intermediate artifacts that we can cache, and our `analyze` step already takes care of caching the full output based on the fingerprint of the input.
 
 ## Technical Details
 
 ### Execution Context
 
-A [Serverless Function](https://zeit.co/docs/v2/advanced/concepts/lambdas) is created where the builder logic is executed. The lambda is run using the Node.js 8 runtime. A brand new sandbox is created for each deployment, for security reasons. The sandbox is cleaned up between executions to ensure no lingering temporary files are shared from build to build.

 All the APIs you export ([`analyze`](#analyze), [`build`](#build) and [`prepareCache`](#preparecache)) are not guaranteed to be run in the same process, but the filesystem we expose (e.g.: `workPath` and the results of calling [`getWriteableDirectory`](#getWriteableDirectory) ) is retained.

 ### Accessing Environment and Secrets
 
-The env and secrets specified by the user as `build.env` are passed to the builder process. This means you can access user env via `process.env` in Node.js.

 ### Utilities as peerDependencies
 
-When you publish your builder to npm, make sure to not specify `@now/build-utils` (as seen below in the API definitions) as a dependency, but rather as part of `peerDependencies`.

-# Versioning
-
-Builders are released to two different channels.
-
-## Channels
-
-| Channel | Git Branch                                                    | npm dist-tag | use example        |
-| ------- | ------------------------------------------------------------- | ------------ | ------------------ |
-| Canary  | [canary](https://github.com/zeit/now/commits/canary)          | `@canary`    | `@now/node@canary` |
-| Stable  | [master](https://github.com/zeit/now/commits/master)          | `@latest`    | `@now/node@latest` |
-
-All PRs are submitted to the `canary` branch. Once a PR is merged into the `canary` branch, it should be published to npm immediately using the Canary Channel.
-
-## Version Selection
-
-Since Builders are published to [npmjs.com](https://npmjs.com), this makes versioning works the same for Builders as it does for any npm package. The `use` statement in [now.json](https://zeit.co/docs/v2/advanced/configuration#builds) has a similar syntax to `npm install`.
-
-The following are valid examples [@now/node](https://www.npmjs.com/package/@now/node?activeTab=versions):
-
-- `@now/node`
-- `@now/node@0.7.3`
-- `@now/node@canary`
-- `@now/node@0.7.2-canary.2`
-
-We always recommend using the latest version by leaving off the dist-tag suffix, `@now/node` for example.
