+
+## Requirements
+- [Node.js](https://nodejs.org/en/) v20 or higher
+
+## Getting Started
+
+This package is available in the Node Package Repository and can be easily installed with [npm](https://docs.npmjs.com/getting-started/what-is-npm) or [yarn](https://yarnpkg.com).
+
+```bash
+$ npm i @nodesecure/mama
+# or
+$ yarn add @nodesecure/mama
+```
+
+## Usage example
+
+```ts
+import { ManifestManager } from "@nodesecure/mama";
+
+const mama = await ManifestManager.fromPackageJSON(
+  process.cwd()
+);
+console.log(mama.document);
+console.log(mama.integrity);
+```
+
+## API
+
+### (static) fromPackageJSON(location: string): Promise< ManifestManager >
+
+Load a new instance using a `package.json` from the filesystem.
+
+The **location** parameter can either be a full path or the path to the directory where the `package.json` is located.
+
+### constructor(document: ManifestManagerDocument)
+
+```ts
+type ManifestManagerDocument =
+  PackageJSON |
+  WorkspacesPackageJSON |
+  PackumentVersion;
+```
+
+Default values are injected if they are not present in the document. This behavior is necessary for the correct operation of certain functions, such as integrity recovery.
+
+```js
+{
+  dependencies: {},
+  devDependencies: {},
+  scripts: {},
+  gypfile: false
+}
+```
+
+> [!NOTE]
+> document is deep cloned (there will no longer be any reference to the object supplied as an argument)
+
+### spec
+Return the NPM specification (which is the combinaison of `name@version`).
+
+> [!CAUTION]
+> This property may not be available for Workspaces (if 'name' or 'version' properties are missing, it will throw an error).
+
+### integrity
+Return an integrity hash (which is a **string**) of the following properties:
+
+```js
+{
+  name,
+  version,
+  dependencies,
+  license: license ?? "NONE",
+  scripts
+}
+```
+
+If `dependencies` and `scripts` are missing, they are defaulted to an empty object `{}`
+
+> [!CAUTION]
+> This is not available for Workspaces
+
+### author
+Return the author parsed as a **Contact** (or `null` if the property is missing).
+
+```ts
+interface Contact {
+  email?: string;
+  url?: string;
+  name: string;
+}
+```
+
+### dependencies and devDependencies
+Return the (dev) dependencies as an Array (of string)
+
+```json
+{
+  "dependencies": {
+    "kleur": "1.0.0"
+  }
+}
+```
+
+The above JSON will produce `["kleur"]`
+
+### isWorkspace
+Return true if `workspaces` property is present
+
+> [!NOTE]
+> Workspace are described by the interface `WorkspacesPackageJSON` (from @nodesecure/npm-types)
+
+### flags
+
+Since we've created this package for security purposes, the instance contains various flags indicating threats detected in the content:
+
+- **isNative**: Contain an identified native package to build or provide N-API features like `node-gyp`.
+- **hasUnsafeScripts**: Contain unsafe scripts like `install`, `preinstall`, `postinstall`...
+
+```ts
+import assert from "node:assert";
+
+const mama = new ManifestManager({
+  name: "hello",
+  version: "1.0.0",
+  scripts: {
+    postinstall: "node malicious.js"
+  }
+});
+
+assert.ok(mama.flags.hasUnsafeScripts);
+```
+
+The flags property is sealed (It is not possible to extend the list of flags)
+
+> [!IMPORTANT]
+> Read more about unsafe scripts [here](https://www.nerdycode.com/prevent-npm-executing-scripts-security/)
