 The Corona crisis has fundamentally changed our world within a very short time.
 The dominant financial system threatens to fail around the globe, followed by mass insolvencies, record unemployment and abject poverty. Only with a sustainable new monetary system can humanity master these challenges of the 21st century. The Gradido Academy for Bionic Economy has developed such a system.
 
+Find out more about the Project on its [Website](https://gradido.net/) offering vast resources about the idea. The remaining document will discuss the gradido software only.
 ## Software requirements
 
-Currently we only support `docker` as environment to run all services, since many different programming languages and frameworks are used.
+Currently we only support `docker` install instructions to run all services, since many different programming languages and frameworks are used.
 
-- [docker](https://www.docker.com/)
+- [docker](https://www.docker.com/) 
+- [docker-compose]
+
+### For Arch Linux
+Install the required packages:
+```bash
+sudo pacman -S docker
+sudo pacman -S docker-compose
+```
+
+Add group `docker` and then your user to it in oder to allow you to run docker without sudo 
+```bash
+sudo groupadd docker # may already exist `groupadd: group 'docker' already exists`
+sudo usermod -aG docker $USER
+groups # verify you have the group (requires relog)
+```
+
+Start the docker service:
+```bash
+sudo systemctrl start docker
+```
 
 ## How to run?
 
-1. Clone the repo and pull all submodules
-
+### 1. Clone Sources
+Clone the repo and pull all submodules
 ```bash
 git clone git@github.com:gradido/gradido.git
 git submodule update --recursive --init
 ```
 
-2. Run docker compose
-    1. Run docker compose for the debug build
+### 2. Run docker-compose
+Run docker-compose to bring up the development environment 
+```bash
+docker-compose up
+```
+### Additional Build options
+If you want to build for production you can do this aswell:
+```bash
+docker-compose -f docker-compose.yml up
+```
 
-    ```bash
-    docker-compose up
-    ```
+## Services defined in this package
 
-   2. Or run docker compose in production build
+- [frontend](./frontend) Wallet frontend
+- [backend](./backend) GraphQL & Business logic backend
+- [mariadb](./mariadb) Database backend
+- [login_server](./login_server) User credential storage & business logic backend
+- [community_server](./community_server/) Business logic backend
 
-    ```bash
-    docker-compose -f docker-compose.yml up
-    ```
+We are currently restructuring the service to reduce dependencies and unify business logic into one place. Furthermore the databases defined for each service will be unified into one.
+
+### Open the wallet
+
+Once you have `docker-compose` up and running, you can open [http://localhost/vue](http://localhost/vue) and create yourself a new wallet account.
+
+## Troubleshooting
+
+| Problem | Issue | Solution | Description |
+| ------- | ----- | -------- | ----------- |
+| docker-compose raises database connection errors | [#1062](https://github.com/gradido/gradido/issues/1062) | End `ctrl+c` and restart the `docker-compose up` after a successful build | Several Database connection related errors occur in the docker-compose log. |
+| Wallet page is empty | [#1063](https://github.com/gradido/gradido/issues/1063) | Accept Cookies and Local Storage in your Browser | The page stays empty when navigating to [http://localhost/vue](http://localhost/vue) |
