 ## Install
 
+### Rebar3
+If you're using [rebar3](https://github.com/erlang/rebar3), add `syn` as a dependency in your project's `rebar.config` file:
+
+```erlang
+{syn, {git, "git://github.com/ostinelli/syn.git", {tag, "1.2.1"}}}
+```
+
+Or, if you're using [Hex.pm](https://hex.pm/) as package manager (with the [rebar3_hex](https://github.com/hexpm/rebar3_hex) plugin):
+
+```erlang
+{syn, "1.2.1"}
+```
+
+Then, compile:
+
+```bash
+$ rebar3 compile
+```

+### Rebar2
 If you're using [rebar](https://github.com/rebar/rebar), add `syn` as a dependency in your project's `rebar.config` file:
 
 ```erlang

+{syn, ".*", {git, "git://github.com/ostinelli/syn.git", {tag, "1.2.1"}}}
