 When creating your containerized Sitecore environment with Docker, you need two files to launch the containers: docker-compose.yml and .env. The docker-compose.yml file contains the configuration of the services that make up the Sitecore environment, such as the roles, networks, volumes, and dependencies. The .env file contains the environment variables that are used by the docker-compose.yml file, such as the Sitecore license path, the image tags, the host names, and the passwords. These files are recommended because they simplify the process of launching the containers and allow you to customize the environment according to your needs. References:

This answer is based on the Sitecore documentation of dynamic placeholders1. Dynamic placeholders are an extension of the regular Sitecore placeholders that allow you to add the same placeholder name several times across multiple renderings, and even within the same rendering. Dynamic placeholders generate a unique key for each placeholder instance, which ensures that the content within the placeholder is unique and not duplicated. Dynamic placeholders also enable you to build functionality that generates multiple placeholders within the same rendering dynamically. For example, you can use dynamic placeholders to create a tab component that can have any number of tabs, each with its own content. References:

The $name token is a special token that can be used in fields on standard values items to instruct Sitecore to set the value of the field to the name of the item upon creation1. This token can be used in rich text, single-line text, and multi-line text fields2. To ensure that items created from a template automatically have the Title field populated with the name of the item, you should add the $name token to the template’s standard values Title field. This way, every item that inherits from the template will have the Title field set to the item name by default. You do not need to set the $name token in the new item’s content Title field, as this will only affect the specific item and not the template. The _name token is not a valid token in Sitecore and will not have any effect. References: 1: 2:
