 Any Linux with a Wifi adapter which can act as an Access Point should also work. Please note that we have tested the Raspberry Pi with clean installations only. If you use your Raspberry Pi for anything else, we recommend using another SD card with a clean installation.
 
@@ -83,26 +84,24 @@ Requirements:
 * docker is installed
 * docker-compose is installed
 
-Create docker image:
+Preparations:
 * git clone https://github.com/ct-Open-Source/tuya-convert
 * cd tuya-convert
-* docker build -t tuya:latest .
-
-Setup docker-compose:
-* copy docker/docker-compose.sample.yml to a new folder you created, the file should be named docker-compose.yml
-* you may adjust this docker-compose.yml, if necessary:
-   * environment-variables may be different, for example network-adapter may be different from wlan0
-   * adjust the volume folder, where you want your backups stored
-
-Run the image:
-* go into the folder you copied docker-compose.yml
-* docker-compose up -d
-* docker-compose exec tuya start
-* tuya-convert now starts within docker
-
-Stop the image:
-* docker-compose exec tuya stop
-* docker-compose down
+* if you have already cloned this repo just cd into the directory and execute `git pull`
+* cp .env-template .env 
+* adjust the created .env-file, it contains usage information as comments
+
+Building and running your container:
+* `docker-compose build && docker-compose run --rm tuya`
+* This directly starts into tuya. If you press ctrl+break or exit tuya after flashing, your container is closed and deleted
+
+Troubleshooting:
+* Q: Where are my logs after flashing? A: The folder can be adjusted in .env with LOCALBACKUPDIR, the path here may be relative or absolute
+* Q: I don't want that my container is deleted after running tuya, I need this for troubleshooting! How do I accomplish this? A: Just remove --rm from `docker-compose run --rm tuya`
+* Q: I want to start the container, but instead of starting tuya immediately I want to get into bash. Is this possible? A: Yes just start the container with `docker-compose run --entrypoint bash tuya`.
+* Q: I want to rebuild my docker-image, even if there are no changes. Is this possible? A: Just start `docker-compose build --no-cache` instead of `docker-compose build`! Don't do this all the time, this is a time consuming process ...
+* Q: I can't connect to my USB, PCI, ... network card. How do I get this working? A: You may have an error in your .env-File. The WLAN-variable should reflect the name of your network interface on your host. Execute ifconfig and look through your interfaces.
+* Q: I can't get an IP-address and or connection on my phone, what's the problem? A: You may look into smarthack-wifi.log (location is set in .env with LOCALBACKUPDIR) or possible stop your firewall (e.g. NixOS seems to have a problem here). It may be a problem with a wrongly set network interface (see previous question)
