+    cd ./Armstrong.Web && \
+    docker compose run --rm web bash -c "make setup"
 ```
 
-Fixing problem:
+This commands cloned repo and setup prroject dependency. Also you can manually install all deps:
 
 ```bash
-usermod -a -G docker $USER
+bundle install
+yarn install
+yarn build
+yarn build:css
+bin/rails db:drop db:create db:migrate db:seed
 ```
 
-Start after system be load:
+## Start
+
+After installing the dependencies, you can run the project in docker compose:
 
 ```bash
-sudo systemctl enable docker
+docker compose up --build
 ```
 
-#### Install [ZSH and Oh-my-zsh](https://ohmyz.sh/)
+That's all. =)
 
-Install:
+## Other options
 
-```bash
-sudo dnf install zsh
-```
+All of the below commands must be executed inside the container. 
 
-```bash
-sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
-```
+Connect to a running container: `docker exec -it armstrongweb_web_1 bash`
+Clean startup with command execution: `docker compose run --rm web bash -c "<your command>"`
 
-Set as default shell:
+### Refresh database
 
 ```bash
-chsh -s $(which zsh)
+make cleanup
 ```
 
-#### Install [git-flow](https://github.com/petervanderdoes/gitflow-avh)
-
-Install:
+### Test and lint
 
 ```bash
-$ wget -q  https://raw.githubusercontent.com/petervanderdoes/gitflow-avh/develop/contrib/gitflow-installer.sh && sudo bash gitflow-installer.sh install stable; rm gitflow-installer.sh
+make check
