 This project contains the core logic of the [WOPI validator](https://wopi.readthedocs.io/en/latest/build_test_ship/validator.html)
 as well as a command-line interface to it.
 
+## Quick start using Docker
+
+You can quickly run the validator using Docker. First, pull the Docker image:
+
+`docker pull tylerbutler/wopi-validator`
+
+Then run the validator using a command like the following:
+
+`docker run -it --rm tylerbutler/wopi-validator -- -w http://localhost:5000/wopi/files/1 -t myToken -l 0 -s`
+
+Note the `--`; parameters after the `--` will be passed to the validator itself

 You can also use the `dotnet run` command, passing the path to the `WopiValidator.csproj` file using the `--project`
 option. Arguments to the validator itself can be passed in by separating them from the `dotnet run` arguments with
 a `--`. For example:
 
 `dotnet run --project ./src/WopiValidator/WopiValidator.csproj --framework netcoreapp2.0 -- -t MyAccessToken -l 0 -w http://localhost:5000/wopi/files/1 -e OfficeOnline -s`

 Another option is to build a self-contained package for your OS (see above) and execute the resulting executable
 file, which be called `Microsoft.Office.Validator.exe` on Windows and `Microsoft.Office.Validator` on Linux and macOS.
