+> Runtime agnostic JS utils
+
+## Installation
+
+```sh
+# Using npm
+npm i std-env
+
+# Using pnpm
+pnpm i std-env
+
+# Using yarn
+yarn add std-env
+```
+
+## Usage
+
+```js
+// ESM
+import { env, isDevelopment, isProduction } from "std-env";
+
+// CommonJS
+const { env, isDevelopment, isProduction } = require("std-env");
+```
+
+## Flags
+
+- `hasTTY`
+- `hasWindow`
+- `isDebug`
+- `isDevelopment`
+- `isLinux`
+- `isMacOS`
+- `isMinimal`
+- `isProduction`
+- `isTest`
+- `isWindows`
+- `platform`
+- `isColorSupported`
+- `nodeVersion`
+- `nodeMajorVersion`
+
+You can read more about how each flag works from [./src/flags.ts](./src/flags.ts).
+
+## Provider Detection
+
+`std-env` can automatically detect the current runtime provider based on environment variables.
+
+You can use `isCI` and `platform` exports to detect it:
+
+```ts
+import { isCI, provider, providerInfo } from "std-env";
+
+console.log({
+  isCI, // true
+  provider, // "github_actions"
+  providerInfo, // { name: "github_actions", isCI: true }
+});
+```
+
+List of well known providers can be found from [./src/providers.ts](./src/providers.ts).
+
+## Runtime Detection
+
+`std-env` can automatically detect the current JavaScript runtime based on global variables, following the [WinterCG Runtime Keys proposal](https://runtime-keys.proposal.wintercg.org/):
+
+```ts
+import { runtime, runtimeInfo } from "std-env";
+
+// "" | "node" | "deno" | "bun" | "workerd" ...
+console.log(runtime);
+
+// { name: "node" }
+console.log(runtimeInfo);
+```
+
+You can also use individual named exports for each runtime detection:
+
+> [!NOTE]
+> When running code in Bun and Deno with Node.js compatibility mode, `isNode` flag will be also `true`, indicating running in a Node.js compatible runtime.
+>
+> Use `runtime === "node"` if you need strict check for Node.js runtime.
+
+- `isNode`
+- `isBun`
+- `isDeno`
+- `isNetlify`
+- `isEdgeLight`
+- `isWorkerd`
+- `isFastly`
+
+List of well known providers can be found from [./src/runtimes.ts](./src/runtimes.ts).
+
+## Platform-Agnostic `env`
+
+`std-env` provides a lightweight proxy to access environment variables in a platform agnostic way.
+
+```ts
+import { env } from "std-env";
+```
+
+## Platform-Agnostic `process`
+
+`std-env` provides a lightweight proxy to access [`process`](https://nodejs.org/api/process.html) object in a platform agnostic way.
+
+```ts
+import { process } from "std-env";
+```
