 ## About
 
-This repository is where the IOTA Foundation's Research Department runs simulations of the Coordicide modules to study and evaluate their performance.
+This repository is where the IOTA Foundation's Research Department tests the Coordicide modules to study and evaluate their performance.
 
 The aim of this open repository is  to give the community the opportunity to follow developments, take part in testing, and learn  more about [Coordicide](https://coordicide.iota.org/).
 
-**Note:** You can find details about future development plans in our [roadmap](https://roadmap.iota.org).

 ## Design
+The code in GoShimmer is modular, where each module represents either one of the [Coordicide components](https://coordicide.iota.org/) or a basic node function such as the gossip, ledger state, API just to mention a few.

+![Layers](images/layers.jpg)
 
-![Coordicide blueprint](images/building-blocks.png)
+GoShimmer modularity is based on a combination of event-driven and layer-based approaches.
 
-This approach allows us to develop each module in parallel and to test GoShimmer with one or more different versions.
-
-Each module is defined in the `packages` directory and can be enabled, using the `plugins` directory.
+Each module is defined in the `packages` directory, with the exceptions for the dApps (e.g., value transfer, network delay and the faucet) that are under the `dapps` folder. Each module can be enabled using the `plugins` directory.
 
 **Note:** See the `main.go` file to see which plugins are currently supported.
 
 ## Implemented Coordicide modules
 
-The `master` branch is the stable version of the GoShimmer software, which includes a minimal set of modules to allow you to send and gossip zero-value transactions.
+The `master` branch is the stable version of the GoShimmer software, which includes a minimal set of modules to allow you to send and gossip the following types of object:
+
+- Generic data object, and more in general, any non-value transfer can be supported with its own dApp/App. 
+- Value objects to issue transactions. 
+- Faucet funding request objects.
 
 The `master` branch includes the following Coordicide modules: 
 
 - [Node identities](https://coordicide.iota.org/module1)
 
-- [Autopeering](https://coordicide.iota.org/module2)

-The autopeering module is divided into two submodules:
+- [Fast Probabilistic Consensus](https://coordicide.iota.org//module4.1.2).  We also have a standalone FPC simulator in this [repository](https://github.com/iotaledger/fpc-sim).
 
-- **Peer discovery:** Responsible for operations such as discovering new peers and verifying their online status
+- [Tip Selection Algorithm](https://coordicide.iota.org//module5)
 
-- **Neighbor selection:** Responsible for finding and managing neighbors
+- [Parallel-reality-based Ledger State](https://iota.cafe/t/parallel-reality-based-ledger-state-using-utxo/261) (using the UTXO model).

 ## Work-in-progress modules
 
-Work-in-progress modules are typically kept on a different branch such as `mana`, and are not compatible with the `master` branch. Therefore, nodes that run these branches cannot join the current network because the code either is still too experimental or it includes breaking changes.

 ## Client-Library and HTTP API reference
 
 You can use the Go client-library to interact with GoShimmer (located under `github.com/iotaledger/goshimmer/client`).
 
-Alternatively, you can check out the [API docs](https://docs.iota.org/docs/node-software/0.1/goshimmer/references/api-reference) 
-to implement your own client or inspect the available HTTP API endpoints.
-
-For code generation, you might want to use the [OAS/Swagger specification file](https://github.com/iotaledger/goshimmer/blob/master/plugins/webapi/api.yaml) directly.
-
-## Installation
-
-You have two options to install and run GoShimmer:
-
-- Use the precompiled executable file
-- Compile the code from source
-
-### Execute the precompiled executable file
-
-The [release page](https://github.com/iotaledger/goshimmer/releases) includes downloadable files for Linux, macOS, and Windows.
-
-To run the node, all you need to do is download and execute one of these files, depending on your operating system.
-
-```bash
-# Linux and macOS
-./goshimmer
-# Windows
-goshimmer.exe
-```
-
-### Compile the code from source
-
-If you want to build your own executable file, you need to follow these steps.
-
-#### Prerequisites
-
-To complete this guide, you need to have at least [version 1.14 of Go installed](https://golang.org/doc/install) on your device.
-
-To check if you have Go installed, run the following command:
-
-```bash
-go version
-```
-
-If Go is installed, you should see the version that's installed.
-
----
-
-1. Clone the repository
-
-    ```bash
-    git clone https://github.com/iotaledger/goshimmer.git
-    ```
-
-2. Change into the `goshimmer` directory
-
-3. Copy and adjust `config.default.json`
-
-    ```bash
-    # Linux and macOS
-    cp config.default.json config.json
-    # Windows
-    copy config.default.json config.json
-    ```
-
-4. Use one of the following commands to build your executable file, depending on your operating system
-
-    ```bash
-    # Linux and macOS
-    go build -o goshimmer
-    # Windows
-    go build -o  goshimmer.exe
-    ```
-
-    **Note:** If you're using Windows PowerShell, enclose `goshimmer.exe` in single quotation marks. For example: go build -o 'goshimmer.exe'.
+You can find more info about this on our [client-lib](https://github.com/iotaledger/goshimmer/wiki/Client-Lib:-Interaction-with-layers) wiki page.
 
 ## Getting started
 
-When you first run GoShimmer, the node starts running and tries to connects to neighbors, using the autopeering module.
-
-To run other modules such as the `spammer`, you can configure GoShimmer to enable them through plugins.
-
-**Note:** For a list of all the available configuration parameters, you can run the following command:
-
-```bash
-# Linux and macOS
-./goshimmer -help
-# Windows
-goshimmer.exe -help
-```
-
-You can configure GoShimmer in the following ways:
-
-* Use a configuration file called `config.json`
-* Use command-line options
-
-The repository includes a `config.json` file, which the executable file will find and use when you execute it.
-
-To use the command line, execute the file with one of the following commands, depending on your operating system
-
-```bash
-# Linux and macOS
-./goshimmer --node.enablePlugins "spammer"
-# Windows
-goshimmer.exe --node.enablePlugins "spammer"
-```
-
-Here, we use the command-line flags to enable the spammer plugin. This plugin allows you to send spam transactions to your node.
-
-### Dashboard
-
-GoShimmer provides access to a SPA dashboard showing TPS, memory chart, neighbors and a Tangle explorer.
-
-You can change its configuration (e.g, bind address, port) under the section `dashboard` of the `config.json` file, for example by changing the bind address to `0.0.0.0:8081` to enable the access from remote and/or by enabling the authentication.
-
-To access the dashboard, you can use your browser (the default address is `http://127.0.0.1:8081`).
