@@ -4,65 +4,8 @@ It is generally advised to use ESM (EcmaScript Modules), whenever possible. At
 this point however, this requires a modern _bundler_ which understands ES2015
 `import/export` syntax, such as [webpack] 4 (or newer).
 
-> In addition, **a compiler
-which translates the subset of ES used by aepp-sdk will have to be used**, such as
-[Babel] - `.babelrc` in the project's root directory, shows which transpilation plugins are required, at least.
-
-### Common Mistakes/Pitfalls
-
-1. **Dev Dependencies**: Make sure to do not forget to double check the `devDependencies` of the `package.json` of this SDK, looking for `@babel`/packages that might be helping you to correctly transpile the SDK code `import`ed into your project, as modules.
-
-2. **ES Modules Transpilation**: Include all the babel packages and plugins needed to transpile _your_ code to the `.babelrc` (or `babel.config.js`) of your project.
-
-3. **Bundlers Setup**: Do not forget to **allow your bundler (eg. _webpack_) to scan the SDK files** that needs transpilation. This will allow your bundler to transpile the SDK `import`ed modules correctly (_see following example_).

-##### Webpack Example:
-```js
- // ... webpack config
- entry: {
-    rules: [
-      {
-        test: /\.js$/,
-        // standard setting for most bundlers web-app setup
-        // entirely excludes the node_modules folder
-        exclude: [/node_modules/],
-        // ...but when using external ES Modules you need to
-        // include required externals ES modules (eg. our Aepp-SDK) like so:
-        include: [/node_modules\/@aeternity/, /node_modules\/rlp/],
-        loader: 'babel-loader'
-      }
-      // ... more rules here (SASS, CSS, etc.)
-    }
-  }
-```

-Using this method also enables the use of [Tree shaking] (dead code
-elimination). In order to ensure that modules are loaded directly, use the following syntax to load your desired part (aka [_flavor_](../README.md)) of aepp-sdk:
-
-```js
-// import Universal stamp
-import Universal from '@aeternity/aepp-sdk/es/ae/universal'
-// import Node
-import Node from '@aeternity/aepp-sdk/es/node'
-// import Account
-import MemoryAccount from '@aeternity/aepp-sdk/es/account/memory'
-
-// interact with aeternity's blockchain
-(async () => {
-  const node = await Node({ url: 'https://testnet.aeternity.io' })
-  const account = MemoryAccount({ keypair: 'YOUR_KEYPAIR' })
-  // Init client
-  const client = await Universal({
-     nodes: [{ name: 'test-net', instance: node }],
-     accounts: [ account ]
-  })
-  client.height().then(height => {
-    console.log('Current Block', height)
-  })
-})()
