 ### Build Commands
 
-- **Build debug version**: `bun bd`
+- **Build Bun**: `bun bd`
   - Creates a debug build at `./build/debug/bun-debug`
-  - **CRITICAL**: DO NOT set a build timeout. Compilation takes ~5 minutes. Be patient.
+  - **CRITICAL**: no need for a timeout, the build is really fast!
 - **Run tests with your debug build**: `bun bd test <test-file>`
   - **CRITICAL**: Never use `bun test` directly - it won't include your changes
 - **Run any command with debug build**: `bun bd <command>`
 
-### Other Build Variants
-
-- `bun run build:release` - Release build
-
-Address sanitizer is enabled by default in debug builds of Bun.
+Tip: Bun is already installed and in $PATH. The `bd` subcommand is a package.json script.

+### Basic Usage
+
+To get started publishing messages, you can set up a publisher in
+`publisher.ts`:
+
+```typescript#publisher.ts
+import { RedisClient } from "bun";
+
+const writer = new RedisClient("redis://localhost:6739");
+await writer.connect();
+
+writer.publish("general", "Hello everyone!");
+
+writer.close();
+```
+
+In another file, create the subscriber in `subscriber.ts`:
+
+```typescript#subscriber.ts

+### Publishing
+
+Publishing messages is done through the `publish()` method:
+
+```typescript

+```
+
+### Subscriptions
+
+The Bun `RedisClient` allows you to subscribe to channels through the
+`.subscribe()` method:
+
+```typescript
+await client.subscribe(channel, (message, channel) => {});
+```
+
+You can unsubscribe through the `.unsubscribe()` method:

+```typescript
+await client.unsubscribe(); // Unsubscribe from all channels.
+await client.unsubscribe(channel); // Unsubscribe a particular channel.
+await client.unsubscribe(channel, listener); // Unsubscribe a particular listener.

+### `Bun.YAML.stringify()`
+
+Convert a JavaScript value into a YAML string. The API signature matches `JSON.stringify`:
+
+```ts
+YAML.stringify(value, replacer?, space?)
+```
+
+- `value`: The value to convert to YAML
+- `replacer`: Currently only `null` or `undefined` (function replacers not yet supported)
+- `space`: Number of spaces for indentation (e.g., `2`) or a string to use for indentation. **Without this parameter, outputs flow-style (single-line) YAML**
+
+#### Basic Usage
+
+```ts
+import { YAML } from "bun";
+
+const data = {
+  name: "John Doe",
+  age: 30,
+  hobbies: ["reading", "coding"],
+};
+
+// Without space - outputs flow-style (single-line) YAML
+console.log(YAML.stringify(data));
+// {name: John Doe,age: 30,hobbies: [reading,coding]}
+
+// With space=2 - outputs block-style (multi-line) YAML
+console.log(YAML.stringify(data, null, 2));
+// name: John Doe
+// age: 30
+// hobbies:
+//   - reading
+//   - coding
+```
+
+#### Output Styles
+
+```ts
+const arr = [1, 2, 3];
+
+// Flow style (single-line) - default
+console.log(YAML.stringify(arr));
+// [1,2,3]
+
+// Block style (multi-line) - with indentation
+console.log(YAML.stringify(arr, null, 2));
+// - 1
+// - 2
+// - 3
+```
+
+#### String Quoting
+
+`YAML.stringify()` automatically quotes strings when necessary:
+
+- Strings that would be parsed as YAML keywords (`true`, `false`, `null`, `yes`, `no`, etc.)
+- Strings that would be parsed as numbers
+- Strings containing special characters or escape sequences
+
+```ts
+const examples = {
+  keyword: "true", // Will be quoted: "true"
+  number: "123", // Will be quoted: "123"
+  text: "hello world", // Won't be quoted: hello world
+  empty: "", // Will be quoted: ""
+};
+
+console.log(YAML.stringify(examples, null, 2));
+// keyword: "true"
+// number: "123"
+// text: hello world
+// empty: ""
+```
+
+#### Cycles and References
+
+`YAML.stringify()` automatically detects and handles circular references using YAML anchors and aliases:
+
+```ts
+const obj = { name: "root" };
+obj.self = obj; // Circular reference
+
+const yamlString = YAML.stringify(obj, null, 2);
+console.log(yamlString);
+// &root
+// name: root
+// self:
+//   *root
+
+// Objects with shared references
+const shared = { id: 1 };
+const data = {
+  first: shared,
+  second: shared,
+};
+
+console.log(YAML.stringify(data, null, 2));
+// first:
+//   &first
+//   id: 1
+// second:
+//   *first
+```
+
+#### Special Values
+
+```ts
+// Special numeric values
+console.log(YAML.stringify(Infinity)); // .inf
+console.log(YAML.stringify(-Infinity)); // -.inf
+console.log(YAML.stringify(NaN)); // .nan
+console.log(YAML.stringify(0)); // 0
+console.log(YAML.stringify(-0)); // -0
+
+// null and undefined
+console.log(YAML.stringify(null)); // null
+console.log(YAML.stringify(undefined)); // undefined (returns undefined, not a string)
+
+// Booleans
+console.log(YAML.stringify(true)); // true
+console.log(YAML.stringify(false)); // false

 ### ES Modules
@@ -184,6 +354,45 @@ const { database, redis } = require("./config.yaml");
 console.log(database.port); // 5432
 ```
 
+### TypeScript Support
+
+While Bun can import YAML files directly, TypeScript doesn't know the types of your YAML files by default. To add TypeScript support for your YAML imports, create a declaration file with `.d.ts` appended to the YAML filename (e.g., `config.yaml` → `config.yaml.d.ts`):
+
+```yaml#config.yaml
+features: "advanced"
+server:
+  host: localhost
+  port: 3000
+```
+
+```ts#config.yaml.d.ts
+const contents: {
+  features: string;
+  server: {
+    host: string;
+    port: number;
+  };
+};
+
+export = contents;
+```
+
+Now TypeScript will provide proper type checking and auto-completion:
+
+```ts#app.ts
+import config from "./config.yaml";
+
+// TypeScript knows the types!
+config.server.port; // number
+config.server.host; // string
+config.features; // string
+
+// TypeScript will catch errors
+config.server.unknown; // Error: Property 'unknown' does not exist
+```
+
+This approach works for both ES modules and CommonJS, giving you full type safety while Bun continues to handle the actual YAML parsing at runtime.
+
 ## Hot Reloading with YAML
 
 One of the most powerful features of Bun's YAML support is hot reloading. When you run your application with `bun --hot`, changes to YAML files are automatically detected and reloaded without closing connections

+
+Bun automatically migrates projects from pnpm to bun. When a `pnpm-lock.yaml` file is detected and no `bun.lock` file exists, Bun will automatically migrate the lockfile to `bun.lock` during installation. The original `pnpm-lock.yaml` file remains unmodified.
+
+```bash
+bun install
+```
+
+**Note**: Migration only runs when `bun.lock` is absent. There is currently no opt-out flag for pnpm migration.
+
+The migration process handles:
+
+### Lockfile Migration
+
+- Converts `pnpm-lock.yaml` to `bun.lock` format
+- Preserves package versions and resolution information
+- Maintains dependency relationships and peer dependencies
+- Handles patched dependencies with integrity hashes
+
+### Workspace Configuration
+
+When a `pnpm-workspace.yaml` file exists, Bun migrates workspace settings to your root `package.json`:
+
+```yaml
+# pnpm-workspace.yaml
+packages:
+  - "apps/*"
+  - "packages/*"
+
+catalog:
+  react: ^18.0.0
+  typescript: ^5.0.0
+
+catalogs:
+  build:
+    webpack: ^5.0.0
+    babel: ^7.0.0
+```
+
+The workspace packages list and catalogs are moved to the `workspaces` field in `package.json`:
+
+```json
+{
+  "workspaces": {
+    "packages": ["apps/*", "packages/*"],
+    "catalog": {
+      "react": "^18.0.0",

+        "babel": "^7.0.0"
+      }
+    }
+  }
+}
+```
+
+### Catalog Dependencies
+
+Dependencies using pnpm's `catalog:` protocol are preserved:
+
+```json
+{
+  "dependencies": {
+    "react": "catalog:",
+    "webpack": "catalog:build"
+  }
+}
+```
+
+### Configuration Migration
+
+The following pnpm configuration is migrated from both `pnpm-lock.yaml` and `pnpm-workspace.yaml`:
+
+- **Overrides**: Moved from `pnpm.overrides` to root-level `overrides` in `package.json`
+- **Patched Dependencies**: Moved from `pnpm.patchedDependencies` to root-level `patchedDependencies` in `package.json`
+- **Workspace Overrides**: Applied from `pnpm-workspace.yaml` to root `package.json`
+
+### Requirements
+
+- Requires pnpm lockfile version 7 or higher
+- Workspace packages must have a `name` field in their `package.json`
+- All catalog entries referenced by dependencies must exist in the catalogs definition
+
+After migration, you can safely remove `pnpm-lock.yaml` and `pnpm-workspace.yaml` files.

+## Concurrent test execution
+
+By default, Bun runs all tests sequentially within each test file. You can enable concurrent execution to run async tests in parallel, significantly speeding up test suites with independent tests.
+
+### `--concurrent` flag
+
+Use the `--concurrent` flag to run all tests concurrently within their respective files:
+
+```sh
+$ bun test --concurrent
+```
+
+When this flag is enabled, all tests will run in parallel unless explicitly marked with `test.serial`.
+
+### `--max-concurrency` flag
+
+Control the maximum number of tests running simultaneously with the `--max-concurrency` flag:

+```sh
+# Limit to 4 concurrent tests
+$ bun test --concurrent --max-concurrency 4
+
+# Default: 20
+$ bun test --concurrent
+```
+
+This helps prevent resource exhaustion when running many concurrent tests. The default value is 20.
+
+### `test.concurrent`
+
+Mark individual tests to run concurrently, even when the `--concurrent` flag is not used:
+
+```ts
+import { test, expect } from "bun:test";
+
+// These tests run in parallel with each other
+test.concurrent("concurrent test 1", async () => {
+  await fetch("/api/endpoint1");

+});
+
+// This test runs sequentially
+test("sequential test", () => {
+  expect(1 + 1).toBe(2);
+});
+```
+
+### `test.serial`

+Force tests to run sequentially, even when the `--concurrent` flag is enabled:

+let sharedState = 0;
+
+// These tests must run in order

+Use the `--randomize` flag to run tests in a random order. This helps detect tests that depend on shared state or execution order.

+
+When using `--randomize`, the seed used for randomization will be displayed in the test summary:

+# ... test output ...
+ --seed=12345
+ 2 pass
+ 8 fail
+Ran 10 tests across 2 files. [50.00ms]
+```
+
+### Reproducible random order with `--seed`
+
+Use the `--seed` flag to specify a seed for the randomization. This allows you to reproduce the same test order when debugging order-dependent failures.
+
+```sh
+# Reproduce a previous randomized run
+$ bun test --seed 123456
+```
+
+The `--seed` flag implies `--randomize`, so you don't need to specify both. Using the same seed value will always produce the same test execution order, making it easier to debug intermittent failures caused by test interdependencies.
+
 ## Bail out with `--bail`
 
 Use the `--bail` flag to abort the test run early after a pre-determined number of test failures. By default Bun will run all tests and report all failures, but sometimes in CI environments it's preferable to terminate earlier to reduce CPU usage.

+// Each test is independent and can run in parallel.
+
+test("fetch user data", async () => {
+  const response = await fetch("/api/user/1");
+  expect(response.ok).toBe(true);
+});
+
+test("fetch posts", async () => {
+  const response = await fetch("/api/posts");
+  expect(response.ok).toBe(true);
+});
+
+test("fetch comments", async () => {
+  const response = await fetch("/api/comments");
+  expect(response.ok).toBe(true);
+});
+```
+
+## Running Tests
+
+```bash
+# Run all tests - concurrent-*.test.ts files will run concurrently
+bun test
+
+# Override: Force ALL tests to run concurrently
+# Note: This overrides bunfig.toml and runs all tests concurrently, regardless of glob
+bun test --concurrent
+
+# Run only unit tests (sequential)
+bun test tests/unit
+
+# Run only integration tests (concurrent due to glob pattern)
+bun test tests/integration
+```
+
+## Benefits
+
+1. **Gradual Migration**: Migrate to concurrent tests file by file by renaming them
+2. **Clear Organization**: File naming convention indicates execution mode
+3. **Performance**: Integration tests run faster in parallel
+4. **Safety**: Unit tests remain sequential where needed
+5. **Flexibility**: Easy to change execution mode by renaming files
+
+## Migration Strategy
+
+To migrate existing tests to concurrent execution:
+
+1. Start with independent integration tests
+2. Rename files to match the glob pattern: `mv api.test.ts concurrent-api.test.ts`
+3. Verify tests still pass
+4. Monitor for race conditions or shared state issues
+5. Continue migrating stable tests incrementally
+
+## Tips
+
+- Use descriptive prefixes: `concurrent-`, `parallel-`, `async-`
+- Keep related sequential tests together
+- Document why certain tests must remain sequential
+- Use `test.concurrent()` for fine-grained control in sequential files
+  (In files matched by `concurrentTestGlob`, plain `test()` already runs concurrently)
+- Consider separate globs for different test types:
+
+```toml
+[test]
+# Multiple patterns for different test categories
+concurrentTestGlob = [
+  "**/integration/*.test.ts",
+  "**/e2e/*.test.ts",
+  "**/concurrent-*.test.ts"
+]
+```

+
+## TypeScript Type Safety
+
+Bun's test runner provides enhanced TypeScript support with intelligent type checking for your test assertions. The type system helps catch potential bugs at compile time while still allowing flexibility when needed.
+
+### Strict Type Checking by Default
+
+By default, Bun's test matchers enforce strict type checking between the actual value and expected value:
+
+```ts
+import { expect, test } from "bun:test";
+
+test("strict typing", () => {
+  const str = "hello";
+  const num = 42;
+
+  expect(str).toBe("hello"); // ✅ OK: string to string
+  expect(num).toBe(42); // ✅ OK: number to number
+  expect(str).toBe(42); // ❌ TypeScript error: string vs number
+});
+```
+
+This helps catch common mistakes where you might accidentally compare values of different types.
+
+### Relaxed Type Checking with Type Parameters
+
+Sometimes you need more flexibility in your tests, especially when working with:
+
+- Dynamic data from APIs
+- Polymorphic functions that can return multiple types
+- Generic utility functions
+- Migration of existing test suites
+
+For these cases, you can "opt out" of strict type checking by providing an explicit type parameter to matcher methods:
+
+```ts
+import { expect, test } from "bun:test";
+
+test("relaxed typing with type parameters", () => {
+  const value: unknown = getSomeValue();
+
+  // These would normally cause TypeScript errors, but type parameters allow them:
+  expect(value).toBe<number>(42); // No TS error, runtime check still works
+  expect(value).toEqual<string>("hello"); // No TS error, runtime check still works
+  expect(value).toStrictEqual<boolean>(true); // No TS error, runtime check still works
+});
+
+test("useful for dynamic data", () => {
+  const apiResponse: any = { status: "success" };
+
+  // Without type parameter: TypeScript error (any vs string)
+  // expect(apiResponse.status).toBe("success");
+
+  // With type parameter: No TypeScript error, runtime assertion still enforced
+  expect(apiResponse.status).toBe<string>("success"); // ✅ OK
+});
+```
+
+### Migration from Looser Type Systems
+
+If migrating from a test framework with looser TypeScript integration, you can use type parameters as a stepping stone:
+
+```ts
+// Old Jest test that worked but wasn't type-safe
+expect(response.data).toBe(200); // No type error in some setups
+
+// Bun equivalent with explicit typing during migration
+expect(response.data).toBe<number>(200); // Explicit about expected type
+
+// Ideal Bun test after refactoring
+const statusCode: number = response.data;
+expect(statusCode).toBe(200); // Type-safe without explicit parameter
+```
