# How to install from source

Use an authorised xitstash checkout.
The repository is private and no artifact is published.

## Prepare the checkout

Install Java 17 or later, Clojure CLI and Babashka.
In the xitstash checkout, compile the Java classes:

```shell
bb javac
```

The command writes classes under `target/classes`.

## Add the application dependency

Add the checkout and xitdb-java to your application’s `deps.edn`.
Replace the local path:

```clojure
{:deps {com.outskirtslabs/xitstash {:local/root "/path/to/xitstash"}
        io.github.radarroark/xitdb {:mvn/version "0.48.0"}}}
```

Start a REPL from the application:

```shell
clojure -M
```

Load the public namespace:

```clojure
(require '[ol.xitstash :as objects])
```

A successful load returns `nil`.
After changing xitstash’s Java source, rerun `bb javac` and restart the application JVM.
