+# Migration Guide: @moltin/sdk to @elasticpath/js-sdk
+
+## Background and rationale
+
+The Elastic Path Commerce Cloud JavaScript SDK has been migrated from `@moltin/sdk` to `@elasticpath/js-sdk`. This was an overdue change, and will allow us to consolidate our version control usage behind the @elasticpath namespace. 
+
+We are also taking this opportunity to entirely remove legacy naming (moltin) from the codebase to avoid confusion.
+
+## Key Changes
+
+- **Package Name**: The package name has changed from `@moltin/sdk` to `@elasticpath/js-sdk`.
+- **GitHub Repository**: The GitHub repository has moved from `moltin/js-sdk` to `elasticpath/js-sdk`.
+
+> ![NOTE]
+> We are aligning the package name with the repository name, i.e. `js-sdk`, rather than just `sdk`. We are reserving the `sdk` name for future use.
+
+## Installation
+
+### Old Package Installation
+
+```bash
+npm install --save @moltin/sdk
+```
+
+### New Package Installation
+
+Replace the old package with the new one:
+
+```bash
+npm install --save @elasticpath/js-sdk
+```
+
+## Example Usage
+
+### Importing the SDK
+
+#### Old Usage
+
+```js
+import { gateway as MoltinGateway } from '@moltin/sdk'
+
+const Moltin = MoltinGateway({
+  client_id: 'XXX'
+})
+```
+
+#### New Usage
+
+
+```js
+import { gateway as ElasticPathGateway } from '@elasticpath/js-sdk'
+
+const ElasticPath = ElasticPathGateway({
+  client_id: 'XXX'
+})
+```
+
+### Migration
+
+1. **Change the import path**: Update all occurrences of `@moltin/sdk` to `@elasticpath/js-sdk`.
+2. **Rename the import alias**: If you are using `MoltinGateway`, change it to `ElasticPathGateway` (or a name of your choice).
+3. **Update instance names**: Rename any instances of `Moltin` to `ElasticPath` to maintain consistency and clarity in your codebase.
+
+If you are directly accessing any of the state the SDK persists in localStorage or cookies, **update your references** like so:
+
+- **mcart** becomes **epcart**
+- **mcurrency** becomes **epcurrency**
+- **moltinCredentials** becomes **epCredentials**
+
+> ![CAUTION]
+> Accessing this SDK state directly is **not recommended**
+
+The compiled SDK and types published in `/dist` as `moltin.cjs.js`, `moltin.d.ts`, `moltin.esm.js`, and `moltin.js` are now published as `index`
