-**devenv** is a tool to quickly build a Docker image based on Ubuntu 22.04 with
+Ваши задачи: 
-easily customisable set of packages. The image is built with an entrypoint script
-which lets you set up an unprivileged user in container OS. 
 
-The whole story is intended for developers needing to experiment with different
+1. Прочитать и прокомментрировать код в файлах: что делает, что можно улучшить.
-versions of build tools etc.
+2. Получить у собеседующего адрес для подключения и пароль пользоваталя **ubuntu**.
-
+3. Подключиться к удаленной машине по ssh и выполнять указания интервьюера.
-## Customise
-1. Customize packages that you want to install into the
-container OS. Just edit the **packages.list** putting
-one package name per line.
-
-2. Add shell scripts or binaries to **./custom** directory. These 
-will run at build time as **root** and the produced result will be 
-baked into the image.
-
-3. **(optional)** edit Makefile, Dockerfile, entrypoint.sh accoriding
-to your requirements.
-
-## Build the image
-This builds Docker image with Ubuntu 22.04 as base
-installing the tools you chose above. Note that build 
-executes all scripts in **./scripts** directory if any are present.
-```bash
-make build
-```
-## Entrypoint
-Entrypoint script creates an unprivileged user in container system.
-Username, gid and uig can be altered when launching the container by passing environment
-variables to docker run.
-
-If no environment variables were passed to docker run, the unprivileged user will
-default to **developer:developer** with uig/gid **1001:1001**.
-
-By default the unprivileged user created by entrpoint script has passwordless sudo.
-If this is not the desired behaviour - consider editing **entrypoint.sh** before
-building the image.
-
-## Create launch script
-This will create a bash script that runs the Docker container from the image 
-built above with your current username, uid and gid. Since username, uid and 
-gid are the same as in your host system you can safely mount anything from 
-your host system into container without creating mess in host OS.
-
-By default the launch script mounts your home directory into the unprivileged 
-user's home in the container. Edit the produced script as  approprite if this 
-is not the desired behaviour.
-```bash
-make script
-```
-
-## Create and install launch script
-This will create the launch script (see above) and place it into you
-**$HOME/.local/bin** creating the directory is if does not exist.
-```bash
-make install 
-```
