 This is the repo for template deployment schemas hosted under `https://schema.management.azure.com/schemas`. Please see below for information on contributing and publishing updated schemas.
 
 ## Updating Schemas
+> [!NOTE]
 > We only publish template schemas for resource providers that are **publicly available**. This means that there should be no restrictions (private preview, internal-only allowlisting) on who can call your APIs. As a general rule, if there is not an API definition in the [Public API Specs Repo](https://github.com/Azure/azure-rest-api-specs), we will not consider a PR.
 
-There are two processes for updating schemas:
-1. **Daily autogeneration**: Schemas are automatically generated from definitions in the [azure-rest-api-specs](https://github.com/Azure/azure-rest-api-specs) repo. This requires [onboarding](/generator/README.md#onboarding-teams-to-autogeneration-pipeline) on a per-provider basis.
-2. **Manually**: Schemas are manually authored and committed via PR.
+Schemas are generated and updated automatically, and should not require any action from RP teams.
 
-### Has my team been onboarded for daily autogeneration?
-Please see [generator/autogenlist.ts](/generator/autogenlist.ts) for the list of teams which have been onboarded. `basePath` refers to the path in the [azure-rest-api-specs](https://github.com/Azure/azure-rest-api-specs) repo, and `namespace` is the Resource Provider namespace.
+## Generating Locally
+If you want to preview or troubleshoot generation locally, you can use the generator in this repo to generate a schema from a swagger spec checked into the [azure-rest-api-specs](https://github.com/Azure/azure-rest-api-specs) repo.
 
-**If your team has been onboarded, we do not require any manual contributions to this repo and your schemas will automatically be kept up to date by the pipeline.**
-
-## Authoring Schemas and submitting a PR
-**Please ensure you have read [Updating Schemas](#updating-schemas) before continuing with this step, and only continue if this applies to your team.**

-#### Generating locally
+### Instructions
 1. Clone [azure-rest-api-specs](https://github.com/Azure/azure-rest-api-specs).
 1. Fork this repo, and clone it locally.
+1. Update submodules and build dependencies:
+    ```bash
+    git submodule update --init --recursive
+    npm --prefix bicep-types-az/bicep-types/src/bicep-types ci
+    npm --prefix bicep-types-az/bicep-types/src/bicep-types run build
+    npm --prefix bicep-types-az/src/autorest.bicep ci
+    npm --prefix bicep-types-az/src/autorest.bicep run build
 1. Run the following commands (replace the base path accordingly - valid paths can be disovered with `npm run list-basepaths -- --specs-dir path/to/azure-rest-api-specs`):
-```bash
-cd generator
-npm install
-npm run generate-single -- --specs-dir path/to/azure-rest-api-specs --base-path myprovider/resource-manager
-```
-1. Review the generator logs to ensure no errors, and review the changes generated.
-1. Ensure that you have reviewed the guidelines under [Submitting a PR](#submitting-a-pr).
-1. Generate a commit and push it to your fork.
-1. Submit a pull request to this repo. Please include the full command output in a PR comment.
-
-Alternatively, you can hand-author your schema, but **please note** that this process is error-prone, and ARM will not be responsible for reviewing for accuracy when validating your PR.
-
-### Submitting a PR
-* Ensure that any $refs to resource types that you are adding has been added to the following top-level template schema: [schemas/2019-04-01/deploymentTemplate.json](/schemas/2019-04-01/deploymentTemplate.json)
-* If your schema has been manually generated, please ensure you include appropriate tests in [tests](/tests/)
-* If adding a new resource type, please add examples to the templates in [tools/templateTests](/tools/templateTests/)
-* Ensure that the test suite passes (see [Tests](#tests))
-
-> **NOTE**: We will no longer be taking any updates to the [2015-01-01](/schemas/2015-01-01/deploymentTemplate.json) or [2014-04-01-preview](/schemas/2014-04-01-preview/deploymentTemplate.json) root schemas. If you are authoring a template which references one of these schemas, please upgrade it to use the [2019-04-01](/schemas/2019-04-01/deploymentTemplate.json) root schema by setting the `$schema` property to `https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#"`.
+    ```bash
+    cd generator
+    npm --prefix generator ci
+    npm --prefix generator run generate-single -- --specs-dir path/to/azure-rest-api-specs --base-path myprovider/resource-manager
+    ```
 
 ### Runing Unit Tests
 Use the following commands to execute the test suite locally:
 ```bash
-cd tools
-npm install
-npm test
+npm --prefix tools ci
+npm --prefix tools test
 ```
 
 ## Manual testing with a local schema server
 This repo contains a command to run a schema web server which will host files directly from your local repo. This can be useful if you want to validate schemas against a particular tool - for example if you want to verify VSCode autocompletion and syntax highlighting. By default this will listen on port 3000, but this can be modified by editing [tools/server.ts](/tools/server.ts).
 To start an instance you can use the following commands:
 ```bash
-cd tools
-npm install
-npm run serve
+npm --prefix tools ci
+npm --prefix tools run serve
 ```
 
 Once this is running, you can create a basic template with the following structure (replacing the sections between `<` and `>` as appropriate for your scenario):
