-As example, if the name of the imported module and the package name are different, this code imports the `f` function from the [`fazy`](https://github.com/pomponchik/fazy) library version `0.0.3`:

-
-print(f('some string'))

-You can also specify only the version or only the package name in the comment, they do not have to be specified together.

-### Using multiple environments
-
-The instld script launch mode provides a unique opportunity to use multiple virtual environments at the same time.
-
-Firstly, you can run scripts in the main virtual environment, and it will work exactly as you expect:
-
-```bash
-python3 -m venv venv
-source venv/bin/activate
-instld script.py
-```
-
-When the "import" command is executed in your script, the package will first be searched in the activated virtual environment, and only then downloaded if it is not found there. Note that by default, the activated virtual environment is read-only. That is, it is assumed that you will install all the necessary libraries there before running your script. If you want to install packages in runtime in a specific virtual environment - read about the second method further.
-
-Secondly, you can specify the path to the virtual environment directly [in the comments](#special-comment-language) to a specific import using the `where` directive:
-
-```python
-import something  # instld: where path/to/the/venv
-```
-
-If the path you specified does not exist when you first run the script, it will be automatically created. Libraries installed in this way are not deleted when the script is stopped, therefore, starting from the second launch, the download is no longer required.
-
-Note that the path to the virtual environment in this case should not contain spaces. In addition, there is no multiplatform way to specify directory paths using a comment. Therefore, it is not recommended to use paths consisting of more than one part.
-
-Since script launch mode uses a context manager to install packages "under the hood", you should also read about the features of installing packages in this way in the [corresponding section](#using-an-existing-virtual-environment).
+In this mode, as in [REPL](#repl-mode), a [special comment language](#special-comment-language) is fully supported.

 > ⚠️  Keep in mind that although inter-thread isolation is used inside the library, working with contexts is not completely thread-safe. You can write code in such a way that two different contexts import different modules in separate threads at the same time. In this case, you may get paradoxical results. Therefore, it is recommended to additionally isolate with mutexes all cases where you import something from contexts in different threads.

 ## How does it work?
 
 This package is essentially a wrapper for `venv` and `pip`.
