+# Installing on an Existing Project
+
+It's also possible to use Symfony Docker with existing projects!
+
+First, [download this skeleton](https://github.com/dunglas/symfony-docker). If you clone the Git repository, be sure to remove the `.git` directory to prevent conflicts with the `.git` directory already in your existing project.
+
+Then, copy the Docker-related files from the skeleton to your existing project:
+
+    cp -Rp symfony-docker/. my-existing-project/
+
+Enable the Docker support of Symfony Flex:
+
+    composer config --json extra.symfony.docker 'true'
+
+Re-execute the recipes to update the Docker-related files according to the packages you use
+
+    rm symfony.lock
+    composer symfony:sync-recipes --force --verbose
+
+Double-check the changes, revert the changes that you don't want to keep:
+
+    git diff
+    ...
+
+Build the Docker images:
+
+    docker compose build --no-cache --pull
+
+Start the project!
+
+    docker compose up -d
+
+Browse `https://localhost`, your Docker configuration is ready!
