 # Garden Snail
 
 Garden Snail is a self-hosted [Remote Cache](https://turbo.build/repo/docs/core-concepts/remote-caching#self-hosting) server for [Turborepo](https://turbo.build/repo) written in [NestJS](https://nestjs.com/).
+
+## Getting started
+
+The easiest way to get started is to use the published [Docker image](https://hub.docker.com/r/pkarolyi/garden-snail). It runs the remote cache server listening on port 3000. Currently only filesystem storage is available for the blobs and they are saved to `/garden-snail/blobs` in the container.
+
+```sh
+docker run -v "$(pwd)"/blobs:/garden-snail/blobs -p 3000:3000 pkarolyi/garden-snail
+```
+
+You can also build and run the application yourself, you will need NodeJS `^20.12` and pnpm `^9.0`:
+
+```sh
+pnpm install
+pnpm build
+node dist/main
+```
+
+## Notes
+
+The `1.0.0` release is working and is compatible with the latest turborepo release (`1.12.4` tested).
+
+This version **does not include any authorization or rate limiting functionality**. It is intended for internal deployments in organizations with external access controls.
+
+## Roadmap
+
+These are the things I will be working on in the coming weeks in no particular order:
+
+- Authorization
+- Rate limiting
+- More providers
