+# actions-languageserver
+
+`actions-languageserver` hosts the `actions-languageservice` and makes it available via the [language server protocol](https://microsoft.github.io/language-server-protocol/) (LSP) as a standalone language server.
+
+## Installation
+
+The [package](https://www.npmjs.com/package/@actions/languageserver) contains TypeScript types and compiled ECMAScript modules.
+
+```bash
+npm install @actions/languageserver
+```
+
+## Usage
+
+### Basic usage using `vscode-languageserver-node`
+
+For the server, import the module. It detects whether it's running in a Node.js environment or a web worker and initializes the appropriate connection.
+
+`server.ts`:
+
+```typescript
+import "@actions/languageserver";
+```
+
+For the client, create a new `LanguageClient` pointing to the server module.
+
+`client.ts`:
+
+```typescript
+import {LanguageClient, ServerOptions, TransportKind} from "vscode-languageclient/node";
+
+const debugOptions = {execArgv: ["--nolazy", "--inspect=6010"]};
+
+const clientOptions: LanguageClientOptions = {
+  documentSelector: [{
+    pattern: "**/.github/workflows/*.{yaml,yml}"
+  }]
+};
+
+const serverModule = context.asAbsolutePath(path.join("dist", "server.js"));
+const serverOptions: ServerOptions = {
+  run: {module: serverModule, transport: TransportKind.ipc},
+  debug: {
+    module: serverModule,
+    transport: TransportKind.ipc,
+    options: debugOptions
+  }
+};
+
+const client = new LanguageClient("actions-language", "GitHub Actions Language Server", serverOptions, clientOptions);
+```
+
+### From a web worker
+
+See [../browser-playground](../browser-playground) for an example implementation that hosts the language server in a web worker.
+
+### Providing advanced functionality
+
+The language server accepts initialization options that can be used to configure additional functionality. If you pass in a github.com `sessionToken`, the language service will use data from github.com to perform additional validations and provide additional auto-completion suggestions.
+
+```typescript
+export interface InitializationOptions {
+  /**
+   * GitHub token that will be used to retrieve additional information from github.com
+   *
+   * Requires the `repo` and `workflow` scopes
+   */
+  sessionToken?: string;
+
+  /**
+   * List of repositories that the language server should be aware of
+   */
+  repos?: RepositoryContext[];
+
+  /**
+   * Desired log level
+   */
+  logLevel?: LogLevel;
+}
+```
+
+pass the `initializationOptions` to the `LanguageClient` when establishing the connection:
+
+```typescript
+const clientOptions: LanguageClientOptions = {
+  documentSelector: [{
+    pattern: "**/.github/workflows/*.{yaml,yml}"
+  }],
+  initializationOptions: initializationOptions
+};
+
+const client = new LanguageClient("actions-language", "GitHub Actions Language Server", serverOptions, clientOptions);

+# actions-languageservice
+
+This package contains the logic for the GitHub Actions workflows language server.
+
+## Installation
+
+The [package](https://www.npmjs.com/package/@actions/languageservice) contains TypeScript types and compiled ECMAScript modules.
+
+```bash
+npm install @actions/languageservice
+```
+
+## Usage
+
+### Basic usage
+
+#### Concepts
+
+The language service features use three sources of information:
+
+* a built-in static schema for the workflow YAML file
+* _value providers_ which can dynamically add values to the schema, for example, the list of available labels for a repository when validating `runs-on`.
+* _context providers_ which can dynamically provide available contexts used in [expressions](https://docs.github.com/actions/reference/context-and-expression-syntax-for-github-actions#about-contexts-and-expressions). For example, the contents of the `github.event` context for a given workflow file.
+
+##### Value Providers
+
+TODO
+
+##### Context Providers
+
+TODO
+
+#### Validation
+
+Validate a workflow file, returns an array of [`Diagnostic`](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#diagnostic) objects.
+
+```typescript
+const config: ValidationConfig = {
+  valueProviderConfig: valueProviders(sessionToken, repoContext, cache),
+  contextProviderConfig: contextProviders(sessionToken, repoContext, cache),
+};
+
+const result = await validate(textDocument, config); // result is an array of `Diagnostic`
+```
+
+#### Hover
+
+Get information when [hovering](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#textDocument_hover) over a token in the workflow file.
+
+```typescript
+import {hover} from "@actions/languageservice";
+
+const document = {
+  uri: "file:///path/to/file",
+  getText: () => "on: push\n  jobs:\n    build:\n      runs-on: ubuntu-latest\n      steps:\n        - run: echo hello"
+};
+
+const hover = await hover(document, {line: 0, character: 1}); // { contents: { kind: "markdown", value: "The event that triggers the workflow" } }
+```
+
+#### Auto-completion
