## REPL
You can try out Bitcoin-S in a REPL in a matter of seconds. Run the provided
["try bitcoin-s"](https://github.com/bitcoin-s/bitcoin-s-core/blob/master/try-bitcoin-s.sh)
script, which has no dependencies other than an installed JDK. The script
downloads and installs [Coursier](https://get-coursier.io/) and uses it to
fetch the [Ammonite](https://ammonite.io) REPL and the latest version of
Bitcoin-S. It then drops you into immediately into a REPL session.
```bash
$ curl -s https://raw.githubusercontent.com/bitcoin-s/bitcoin-s/master/try-bitcoin-s.sh | bash

@ address.value # Tada! You've just made a Bech32 address

## Getting prebuilt JARs
If you want to add Bitcoin-S to your project, follow the
instructions for your build tool
### sbt
Add this to your `build.sbt`:
```scala
libraryDependencies +="org.bitcoin-s" % "bitcoin-s-secp256k1jni" % "0.2.0"
libraryDependencies += "org.bitcoin-s" %% "bitcoin-s-core" % "0.2.0"
libraryDependencies += "org.bitcoin-s" %% "bitcoin-s-bitcoind-rpc" % "0.2.0"
libraryDependencies += "org.bitcoin-s" %% "bitcoin-s-eclair-rpc" % "0.2.0"
libraryDependencies += "org.bitcoin-s" %% "bitcoin-s-testkit" % "0.2.0"
libraryDependencies += "org.bitcoin-s" %% "bitcoin-s-zmq" % "0.2.0"
```
### Nightly builds
You can also run on the bleeding edge of Bitcoin-S, by
adding a snapshot build to your `build.sbt`. The most
recent snapshot published is `0.2.0+129-56f20393+20191222-0903-SNAPSHOT`.
To fetch snapshots, you will need to add the correct
resolver in your `build.sbt`:
```sbt
resolvers += Resolver.sonatypeRepo("snapshots")
```

TODO
## Building JARs yourself
If you want to build Bitcoin-S JARs yourself, you need to use the
[sbt](https://www.scala-sbt.org/) build tool. Once you have sbt
installed, run `sbt publishLocal`. This places the required JAR
files in your `.ivy2/local` folder. On Linux, this is located at
`$HOME/.ivy2/local/` by default.
