 ## Installation
 
 It is recommended to install Skipper directly from PyPi:
-```bash
+
+```shell
 sudo pip install strato-skipper
-```
+``` 
 
 You can also install Skipper from source:
-``` bash 
+
+``` shell
 git clone http://github.com/Stratoscale/skipper
 sudo make install
 ```
 
 Configure bash completion for skipper by sourcing the completion script in your ~/.bashrc file:
+
 ``` bash
 echo 'source <(skipper completion)' >>~/.bashrc
 ```
 
 ## Python3 Environment
+
 Skipper supports building and running in Python3 environment
 Set your locale to UTF-8:
-```bash
+
+```shell
 export LC_ALL="en_US.UTF-8"
 export LANG="en_US.UTF-8"
 ```
+
+## Note for Linux Users with Docker
+
+If you run on Linux and use Docker without sudo, Skipper will create a dedicated user inside the build container with both root and docker groups. Commands are executed on behalf of this user.
+
+To preserve the environment (e.g., PATH), Skipper uses the `su` command with the `-m` flag. However, on Debian distros, even with the `-m` flag specified, the PATH variable may be reset. As a workaround, Skipper attempts to use `sudo -sE` (if installed) as an alternative to maintain the environment.
+
+If you prefer to use sudo, please install it in the build container. Additionally, it is required to disable `env_reset` with `secure_path` in `/etc/sudoers` Deafults.
+
+**Note:** This information is crucial for a seamless experience when using Skipper with Docker on Linux.

 ## Usage
 
 Skipper can serve as your primary tool for your daily development tasks:
+
 * Use `skipper build` to build the images defined by the Dockerfiles in your repository. All the images will be automatically tagged with the *COMMIT_ID*.
 * Use `skipper push` to publish your images.
 * Use `skipper images` to list your images.

 ### [Build context explained](https://www.docker.com/blog/dockerfiles-now-support-multiple-build-contexts/)
+
 Skipper allows you to add additional build contexts when running the build command, give them a name, and then access them inside a Dockerfile.
 The build context can be one of the following:
+
 * Local directory – e.g. `--build-context project2=../path/to/project2/src`
 * Git repository – e.g. `--build-context qemu-src=https://github.com/qemu/qemu.git`
 * HTTP URL to a tarball – e.g. `--build-context src=https://example.org/releases/src.tar`

 ### Build
+
 As a convention, skipper infers the docker images from the Dockerfiles in the top directory of your repository. For example, assuming that there are 3 Dockerfile in the top directory of the repository:
+
 ```
 Dockerfile.service1
 Dockerfile.service2
 Dockerfile.development
 ```
 
 To build the image that corresponeds to `Dockerfile.service1`, run:
-```bash
+
+```shell
 skipper build service1
 ```
 
 In the same way you can build the image corresponded to `Dockerfile.development`:
-```bash
+
+```shell
 skipper build development
 ```
 
 You can also build mutliple images with single command:
-```bash
+
+```shell
 skipper build development service2
 ```
 
 A context path can be added to the build command, The build’s context is the files at a specified location PATH, the default is current directory:
-```bash
+
+```shell
 skipper buid service1 --container-context /path/to/context/dir
 ```
 
 If no image is specifed skipper will build all detected images:
-```bash
+
+```shell
 skipper build
 ```
 
 If you don't want to store all the Dockerfiles under the top directory of the project, you can specify the project's containers in skipper's config file (see below).
 
 ### Push
+
 Once you've built the images of your repositories as described above. You can publish them by pushing them to the registry.
 To push the `service1` image, run:
-```bash
+
+```shell
 skipper --registry some-registry push service1
 ```
+
 Note that the registry in this command must be the same registry used while building the image.
 
 ### Images
+
 To list local images of your repository, run:
-```bash
+
+```shell
 skipper images
 ```
 
 In order to also list also images that were pushed to the registry, run:
-```bash
+
+```shell
 skipper --registry some-registry images -r
 ```
 
 ### Rmi
+
 To delete an image of your repository, run:
-```bash
+
+```shell
 skipper rmi service1 <tag>
 ```
 
 In order to delete the image from the registry, run:
-```bash
+
+```shell
 skipper --registry some-registry rmi -r service1 <tag>
 ```
 
 ### Make
+
 You can execute a Makefile target inside a container. This is good for keeping the development in an isolated environment, without installing development tools on the host. Once a development container is defined and built, it can be shared among the team member, assuring all of them use exactly thg same development environment.
 Assuming your project has a Makefile with a `tests` target, you can run:
-```bash
+
+```shell
 skipper --registry some-registry --build-container-image development --build-container-tag latest \
 make tests
 ```
 
 If your Makefile is not standard (i.e. `Makefile.arm32`) you can pass it to the make command:
-```bash
+
+```shell
 skipper --registry some-registry --build-container-image development --build-container-tag latest \
 make -f Makefile.arm32 tests
 ```
 
 ### Run

-### Variable substitution:
 Skipper uses the variable values from the shell environment in which skipper is run.
 It’s possible to use environment variables in your shell to populate values
 For example, suppose the shell contains EXTERNAL_PORT=5000 and you supply this configuration:
-````
+
+````yaml
 env:
     EXTERNAL_PORT: $EXTERNAL_PORT
 ````
+
 When you run Skipper command with this configuration, Skipper looks for the EXTERNAL_PORT environment variable in the shell and substitutes its value in.In this example, Skipper resolves the `$EXTERNAL_PORT` to "5000" and will set EXTERNAL_PORT=5000 environment in the container.
 
 If an environment variable is not set, Skipper substitutes with an empty string.
 
 Both `$VARIABLE` and `${VARIABLE}` syntax are supported. Extended shell-style features, such as `${VARIABLE-default}` and `${VARIABLE/foo/bar}`, are not supported.
 
 You can use a `$$` (double-dollar sign) when your configuration needs a literal dollar sign. This also prevents Skipper from interpolating a value, so a `$$` allows you to refer to environment variables that you don’t want processed by Skipper.
