+## Getting started
+![](./docs/warning.svg)
+**Warning**: logsmith will write in your `.aws/credentials` and `./aws/config` files and part of its feature set is to remove unused profiles.
+This includes potential **access-keys** (which are profiles as well). If you have data in there that must not be lost, please back up the data beforehand.
+
+Logsmith identifies access-keys if their profile name starts with `access-key` (e.g. `access-key` or `access-key-foo`) and will not remove them.
+
+### Run from source
+If you want to run logsmith from source, please use the following steps:
+
+#### 1. Clone this repository
+```bash
+git clone https://github.com/otto-de/logsmith.git
+cd logsmith
+```
+
+#### 2. Install the dependencies
+```bash
+./setup.sh
+```
+This will create a venv.
+
+#### 3. Run application
+```bash
+./run.sh
+```
+After startup, a small cloud should appear in the start bar (this application has no main window).
+
+#### 4. Add access-key (aws) 
+Click on the cloud and select "Set access key".
+
+A dialog will appear where you can add your access key data. Please be advised that an access-key must start with the prefix `access-key`. The default name is simply `access-key`.
+
+#### 5. Add configuration
+To add your configuration for the accounts and profiles (aka profile groups) you want to login in, click on the cloud and select "Edit Config".
+
+A dialog will appear where you can add your configuration in a text form. This config must be YAML conform, please see in the [Configuration](#Configuration) section down below for more instructions.
+
+If you have used another name for your **access-key**, you may set it in the profile group, or you may set a default access-key name in the config dialog.
+
+#### 6. Select a profile group
+To start the login process, click on the cloud and select the profile group you want to login in, on success the cloud will change its color to the color you have set in the configuration. The login process will be repeated every 5 minutes to keep you logged in.
+
+If an error occurs, the cloud icon will turn into a red bug. To see the error, click on the cloud and select "Show logs".
+
+Be advised that in some cases a dialog may be opened in the background and will not appear in the taskbar.
