+## Docker wrapper
+
+This project includes a docker wrapper for development. Any command can be executed by calling the scripts under the `dbin/` folder.
+
+```sh
+$ dbin/yarn dev
+
+$ dbin/yarn debug
+
+$ dbin/yarn cli
+
+$ dbin/yarn remote [server address] [REPL port]
+```
+
+The container runs using host networking, so there's no need to map ports. Keep in mind that environment variables should be added to the docker-compose.yml.
+
+### Wrapper commands
+
+```sh
+# Runs the command inside an ephemeral container using the app service described in the docker-compose file as a base (use the --root flag if the command should be run as root)
+$ dbin/run [--root] <command>
+
+# Rebuild the image after any changes to the dockerfile
+$ dbin/build
+
+# Remove all containers and their volumes (WARNING any cache or files not stored in the filesystem will be deleted)
+$ dbin/dispose
+
+# Appends a RUN command to the base image, useful to install new packages
+$ dbin/chimg <command>
+```
+
+### Wrapper Aliases
+
+```sh
+# Creates a new <name> file in dbin to alias the <command> inside the docker container (use the --root flag if the command should be run as root)
+$ dbin/mkalias [--root] <name> <command>
+
+# Opens a new terminal in the project folder (use the --root flag if the shell should assume the root user)
+$ dbin/shell [--root]
+
+# Runs npm in the project folder
+$ dbin/npm
+
+# Runs npx in the project folder
+$ dbin/npx
+
+# Runs yarn in the project folder
+$ dbin/yarn
+```
+
+### Wrapper Helpers
+
+```bash
+# Adds dbin folder to the PATH only for the current terminal session.
+$ source dbin/local-env
+
+# After using this command you can use the any script inside the dbin folder without the dbin/ prefix
+```

 ## Dependency injection
 
 We use [Awilix](https://www.npmjs.com/package/awilix) to implement dependency injection and decouple the parts of your application. The boilerplate was developed in a way that each [module](#modules) is able to consume and augment the registered dependencies separately. Click here to know more about [inversion of control and dependency injection](https://www.martinfowler.com/articles/injection.html). The creator of Awilix also has a very good series of posts about the design decisions of the library that you can read [clicking here](https://medium.com/@Jeffijoe/dependency-injection-in-node-js-2016-edition-f2a88efdd427).
