+# Run Super-Linter locally to test your branch of code
+If you want to test locally against the **Super-Linter** to test your branch of code, you will need to complete the following:
+- Clone your testing source code to your local environment
+- Install Docker to your local environment
+- Pull the container down
+- Run the container
+- Debug/Troubleshoot
+
+## Install Docker to your local machine
+You can follow the link below on how to install and configure **Docker** on your local machine
+- [Docker Install Documentation](https://docs.docker.com/install/)
+
+## Download the latest Super-Linter Docker container
+- Pull the latest **Docker** container down from **DockerHub**
+  - `docker pull admiralawkbar/super-linter:latest`
+Once the container has been downloaded to your local environment, you can then begin the process, or running the container against your codebase.
+
+## Run the container Locally
+- You can run the container locally with the following **Base** flags to run your code:
+  - `docker run -e RUN_LOCAL=true -v /path/to/local/codebase:/tmp/lint admiralawkbar/super-linter`
+  - **NOTE:** You need to pass the `RUN_LOCAL` flag to bypass some of the GitHub Actions checks, as well as the mapping of your local codebase to `/tmp/lint` so that the linter can pick up the code
+  - **NOTE:** The flag:`RUN_LOCAL` will set: `VALIDATE_ALL_CODEBASE` to true. This means it will scan **all** the files in the directory you have mapped. If you want to only validate a subset of your codebase, map a folder with only the files you wish to have linted
+- You can add as many **Additional** flags as needed:
+  - **VALIDATE_YAML**
+    - `-e VALIDATE_YAML=<true|false>`
+    - Default: `true`
+    - Flag to enable or disable the linting process of the language
+  - **VALIDATE_JSON**
+    - `-e VALIDATE_JSON=<true|false>`
+    - Default: `true`
+    - Flag to enable or disable the linting process of the language
+  - **VALIDATE_XML**
+    - `-e VALIDATE_XML=<true|false>`
+    - Default: `true`
+    - Flag to enable or disable the linting process of the language
+  - **VALIDATE_MD**
+    - `-e VALIDATE_MD=<true|false>`
+    - Default: `true`
+    - Flag to enable or disable the linting process of the language
+  - **VALIDATE_BASH**
+    - `-e VALIDATE_BASH=<true|false>`
+    - Default: `true`
+    - Flag to enable or disable the linting process of the language
+  - **VALIDATE_PERL**
+    - `-e VALIDATE_PERL=<true|false>`
+    - Default: `true`
+    - Flag to enable or disable the linting process of the language
+  - **VALIDATE_PYTHON**
+    - `-e VALIDATE_PYTHON=<true|false>`
+    - Default: `true`
+    - Flag to enable or disable the linting process of the language
+  - **VALIDATE_RUBY**
+    - `-e VALIDATE_RUBY=<true|false>`
+    - Default: `true`
+    - Flag to enable or disable the linting process of the language
+  - **VALIDATE_COFFEE**
+    - `-e VALIDATE_COFFEE=<true|false>`
+    - Default: `true`
+    - Flag to enable or disable the linting process of the language
+  - **VALIDATE_ANSIBLE**
+    - `-e VALIDATE_ANSIBLE=<true|false>`
+    - Default: `true`
+    - Flag to enable or disable the linting process of the language
+  - **VALIDATE_JAVASCRIPT**
+    - `-e VALIDATE_JAVASCRIPT=<true|false>`
+    - Default: `true`
+    - Flag to enable or disable the linting process of the language
+  - **ANSIBLE_DIRECTORY**
+    - `-e ANSIBLE_DIRECTORY=</path/local/to/codebase/with/ansible>`
+    - Default: `/ansible`
+    - Flag to set the root directory for Ansible file location(s)
+
+## Troubleshooting
+
+### Run container and gain access to the command line
+If you need to run the container locally and gain access to its command line, you can run the following command:
+- `docker run -it --entrypoint /bin/bash admiralawkbar/super-linter`
+- This will drop you in the command line of the docker container for any testing or troubleshooting that may be needed.
