+# Quick Start
+
+Let's start your Garage journey!
+In this chapter, we explain how to deploy Garage as a single-node server
+and how to interact with it.
+
+Our goal is to introduce you to Garage's workflows.
+Following this guide is recommended before moving on to
+[configuring a real-world deployment](../cookbook/real_world.md).
+
+Note that this kind of deployment should not be used in production, as it provides
+no redundancy for your data!
+We will also skip intra-cluster TLS configuration, meaning that if you add nodes
+to your cluster, communication between them will not be secure.
+
+## Get a binary
+
+Download the latest Garage binary from the release pages on our repository:
+
+<https://git.deuxfleurs.fr/Deuxfleurs/garage/releases>
+
+Place this binary somewhere in your `$PATH` so that you can invoke the `garage`
+command directly (for instance you can copy the binary in `/usr/local/bin`
+or in `~/.local/bin`).
+
+If a binary of the last version is not available for your architecture,
+you can [build Garage from source](../cookbook/from_source.md).
+
+
+## Writing a first configuration file
+
+This first configuration file should allow you to get started easily with the simplest
+possible Garage deployment:
+
+```toml
+metadata_dir = "/tmp/meta"
+data_dir = "/tmp/data"
+
+replication_mode = "none"
+
+rpc_bind_addr = "[::]:3901"
+
+bootstrap_peers = []
+
+[s3_api]
+s3_region = "garage"
+api_bind_addr = "[::]:3900"
+
+[s3_web]
+bind_addr = "[::]:3902"
+root_domain = ".web.garage"
+index = "index.html"
+```
+
+Save your configuration file as `garage.toml`.
+
+As you can see in the `metadata_dir` and `data_dir` parameters, we are saving Garage's data
+in `/tmp` which gets erased when your system reboots. This means that data stored on this
+Garage server will not be persistent. Change these to locations on your local disk if you want
+your data to be persisted properly.
+
+
+## Launching the Garage server
+
+Use the following command to launch the Garage server with our configuration file:
+
+```
+garage server -c garage.toml
+```
+
+By default, Garage displays almost no output. You can tune Garage's verbosity as follows
+(from less verbose to more verbose):
+
+```
+RUST_LOG=garage=info garage server -c garage.toml
+RUST_LOG=garage=debug garage server -c garage.toml
+RUST_LOG=garage=trace garage server -c garage.toml
+```
+
+Log level `info` is recommended for most use cases.
+Log level `debug` can help you check why your S3 API calls are not working.
+
+
+## Checking that Garage runs correctly
+
+The `garage` utility is also used as a CLI tool to configure your Garage deployment.
+It tries to connect to a Garage server through the RPC protocol, by default looking
+for a Garage server at `localhost:3901`.
+
+Since our deployment already binds to port 3901, the following command should be sufficient
+to show Garage's status:
+
+```
+garage status
+```
+
+This should show something like this:
+
+```
+Healthy nodes:
+2a638ed6c775b69a… linuxbox 127.0.0.1:3901 UNCONFIGURED/REMOVED
+```
+
+## Configuring your Garage node
+
+Configuring the nodes in a Garage deployment means informing Garage
+of the disk space available on each node of the cluster
+as well as the zone (e.g. datacenter) each machine is located in.
+
+For our test deployment, we are using only one node. The way in which we configure
+it does not matter, you can simply write:
+
+```bash
+garage node configure -z dc1 -c 1 <node_id>
+```
+
+where `<node_id>` corresponds to the identifier of the node shown by `garage status` (first column).
+You can enter simply a prefix of that identifier.
+For instance here you could write just `garage node configure -z dc1 -c 1 2a63`.
+
+
+
+
+## Creating buckets and keys
+
+In this section, we will suppose that we want to create a bucket named `nextcloud-bucket`
+that will be accessed through a key named `nextcloud-app-key`.
+
+Don't forget that `help` command and `--help` subcommands can help you anywhere,
+the CLI tool is self-documented! Two examples:
+
+```
+garage help
+garage bucket allow --help
+```
+
+#### Create a bucket
+
+Let's take an example where we want to deploy NextCloud using Garage as the
+main data storage.
+
+First, create a bucket with the following command:
+
+```
+garage bucket create nextcloud-bucket
+```
+
+Check that everything went well:
+
+```
+garage bucket list
+garage bucket info nextcloud-bucket
+```
+
+#### Create an API key
+
+The `nextcloud-bucket` bucket now exists on the Garage server,
+however it cannot be accessed until we add an API key with the proper access rights.
+
+Note that API keys are independent of buckets:
+one key can access multiple buckets, multiple keys can access one bucket.
+
+Create an API key using the following command:
+
+```
+garage key new --name nextcloud-app-key
+```
+
+The output should look as follows:
+
+```
+Key name: nextcloud-app-key
+Key ID: GK3515373e4c851ebaad366558
+Secret key: 7d37d093435a41f2aab8f13c19ba067d9776c90215f56614adad6ece597dbb34
+Authorized buckets:
+```
+
+Check that everything works as intended:
+
+```
+garage key list
+garage key info nextcloud-app-key
+```
+
+#### Allow a key to access a bucket
+
+Now that we have a bucket and a key, we need to give permissions to the key on the bucket:
+
+```
+garage bucket allow \
+ --read \
+ --write
+ nextcloud-bucket \
+ --key nextcloud-app-key
+```
+
+You can check at any time the allowed keys on your bucket with:
+
+```
+garage bucket info nextcloud-bucket
+```
+
+
+## Uploading and downlading from Garage
+
+We recommend the use of MinIO Client to interact with Garage files (`mc`).
+Instructions to install it and use it are provided on the
+[MinIO website](https://docs.min.io/docs/minio-client-quickstart-guide.html).
+Before reading the following, you need a working `mc` command on your path.
+
+Note that on certain Linux distributions such as Arch Linux, the Minio client binary
+is called `mcli` instead of `mc` (to avoid name clashes with the Midnight Commander).
+
+#### Configure `mc`
+
+You need your access key and secret key created above.
+We will assume you are invoking `mc` on the same machine as the Garage server,
+your S3 API endpoint is therefore `http://127.0.0.1:3900`.
+For this whole configuration, you must set an alias name: we chose `my-garage`, that you will used for all commands.
+
+Adapt the following command accordingly and run it:
+
+```bash
+mc alias set \
+ my-garage \
+ http://127.0.0.1:3900 \
+ <access key> \
+ <secret key> \
+ --api S3v4
+```
+
+You must also add an environment variable to your configuration to
+inform MinIO of our region (`garage` by default, corresponding to the `s3_region` parameter
+in the configuration file).
+The best way is to add the following snippet to your `$HOME/.bash_profile`
+or `$HOME/.bashrc` file:
+
+```bash
+export MC_REGION=garage
+```
+
+#### Use `mc`
+
+You can not list buckets from `mc` currently.
+
+But the following commands and many more should work:
+
+```bash
+mc cp image.png my-garage/nextcloud-bucket
+mc cp my-garage/nextcloud-bucket/image.png .
+mc ls my-garage/nextcloud-bucket
+mc mirror localdir/ my-garage/another-bucket
+```
+
+
+#### Other tools for interacting with Garage
+
+The following tools can also be used to send and recieve files from/to Garage:
+
+- the [AWS CLI](https://aws.amazon.com/cli/)
+- [`rclone`](https://rclone.org/)
+- [Cyberduck](https://cyberduck.io/)
+- [`s3cmd`](https://s3tools.org/s3cmd)
+
+Refer to the ["configuring clients"](../cookbook/clients.md) to learn how to configure
+these clients to interact with a Garage server.
