+# Contributing
+
+When contributing to this repository, please first discuss the change you wish to make via issue or [spectrum](https://spectrum.chat/zeit) with the owners of this repository before submitting a Pull Request.
+
+Please read our [code of conduct](CODE_OF_CONDUCT.md) and follow it in all your interactions with the project.
+
+## Local development
+
+This project is configured in a monorepo pattern where one repo contains multiple npm packages. Dependencies are installed and managed with `yarn`, not `npm` CLI. 
+
+To get started, execute the following:
+
+```
+git clone https://github.com/zeit/now-builders
+yarn install
+yarn bootstrap
+yarn build
+yarn lint
+yarn test
+```
+
+Make sure all the tests pass before making changes.
+
+## Verifying your change
+
+Once you are done with your changes (we even suggest doing it along the way ), make sure all the test still run by running
+
+```
+yarn build && yarn test
+```
+
+from the root of the project.
+
+If any test fails, make sure to fix it along with your changes. See [Interpreting test errors](#Interpreting-test-errors) for more information about how the tests are executed, especially the integration tests.
+
+## Pull Request Process
+
+Once you are confident that your changes work properly, open a pull request on the main repository.
+
+The pull request will be reviewed by the maintainers and the tests will be checked by our continuous integration platform.
+
+## Interpreting test errors
+
+There are 2 kinds of tests in this repository – Unit tests and Integration tests.
+ 
+Unit tests are run locally with `jest` and execute quickly because they are testing the smallest units of code.
+
+### Integration tests
+
+Integration tests create deployments to your ZEIT account using the `test` project name. After each test is deployed, the `probes` key is used to check if the response is the expected value. If the value doesn't match, you'll see a message explaining the difference. If the deployment failed to build, you'll see a more generic message like the following:
+
+```
+[Error: Fetched page https://test-8ashcdlew.now.sh/root.js does not contain hello Root!. Instead it contains An error occurred with this application.
+
+    NO_STATUS_CODE_FRO Response headers:
+       cache-control=s-maxage=0
+      connection=close
+      content-type=text/plain; charset=utf-8
+      date=Wed, 19 Jun 2019 18:01:37 GMT
+      server=now
+      strict-transport-security=max-age=63072000
+      transfer-encoding=chunked
+      x-now-id=iad1:hgtzj-1560967297876-44ae12559f95
+      x-now-trace=iad1]
+```
+
+In such cases you can visit the URL of the failed deployment and append `/_logs` so see the build error. In the case above, that would be https://test-8ashcdlew.now.sh/_logs
+
+The logs of this deployment will contain the actual error which may help you to understand what went wrong.
+
+### @zeit/ncc integration
+
+Some of the builders use `@zeit/ncc` to bundle files before deployment. If you suspect an error with the bundling mechanism, you can run the `ncc` CLI with a couple modifications to the test.
+
+For example if an error occurred in `now-node/test/fixtures/08-assets`
+
+```
+cd packages/now-node/test/fixtures/08-assets
+yarn install
+echo 'require("http").createServer(module.exports).listen(3000)' >> index.js
+npx @zeit/ncc@0.20.1 build index.js --source-map
+node dist
+```
+
+This will compile the test with the specific version of `ncc` and run the resulting file. If it fails here, then there is likely a bug in `ncc` and not the Builder.

 # now-builders
 
-This is the full list of official Builders provided by the ZEIT team.
+This is a monorepo containing the [Official Builders](https://zeit.co/docs/v2/deployments/builders/overview) provided by the ZEIT team.
 
-More details here: https://zeit.co/docs/v2/deployments/builders/overview/
+## Channels
+
+There are two Channels:
+
+| Channel | Git Branch | npm dist-tag | use example        |
+| ------- | ---------- | ------------ | ------------------ |
+| Canary  | `canary`   | `@canary`    | `@now/node@canary` |
+| Stable  | `master`   | `@latest`    | `@now/node@latest` |
+
+All PRs should be 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.
 
 ### Publishing to npm
 
-Run the following command to publish modified builders to npm:
-
-For the stable channel use:
-
-```
-yarn publish-stable
-```
-
-For the canary channel use:
+For the Canary Channel, publish the modified Builders to npm with the following:
 
 ```
 yarn publish-canary
 ```
 
-CircleCI will take care of publishing the updated packages to npm from there.
+For the Stable Channel, you must do the following:
+- Cherry pick each commit from canary to master
+- Verify that you are *in-sync* with canary (with the exception of the `version` line in `package.json`)
+- Deploy the modified Builders
 
-If for some reason CircleCI fails to publish the npm package, you may do so
+```
+git checkout master
+git pull      # make sure you're up to date
+git cherry-pick <PR501_COMMIT_SHA>
+git cherry-pick <PR502_COMMIT_SHA>
+git cherry-pick <PR503_COMMIT_SHA>
+git cherry-pick <PR504_COMMIT_SHA>
+# ... etc ...
+git diff origin/canary
+yarn publish-stable
+```
+
+After running this publish step, GitHub Actions will take care of publishing the modified Builder packages to npm.
+
+If for some reason GitHub Actions fails to publish the npm package, you may do so
 manually by running `npm publish` from the package directory. Make sure to
-include the `--tag canary` parameter if you are publishing a canary release!
+use `npm publish --tag canary` if you are publishing a canary release!

+# `@now/static-build` Failed to detect a server running
+
+#### Why This Warning Occurred
+
+When running `now dev`, the `@now/static-build` builder proxies relevant HTTP
+requests to the server that is created by the `now-dev` script in the
+`package.json` file.
+
+In order for `now dev` to know which port the server is running on, the builder
+is provided a `$PORT` environment variable that the server _must_ bind to. The
+error "Failed to detect a server running on port" is printed if the builder fails
+to detect a server listening on that specific port within five minutes.
+
+#### Possible Ways to Fix It
+
+Please ensure that your `now-dev` script binds the spawned development server on
+the provided `$PORT` that the builder expects the server to bind to.
+
+For example, if you are using Gatsby, your `now-dev` script must use the `-p`
+(port) option to bind to the `$PORT` specified from the builder:
+
+```
+{
+  ...
+  "scripts": {
+    ...
+    "now-dev": "gatsby develop -p $PORT"
+  }
+}
+```
+
+Consult your static builder program's `--help` or documentation to figure out what
+the command line flag to bind to a specific port is (in many cases, it is one of:
+`-p` / `-P` / `--port`).
