+## Install interpreters
+
+You can install additional [interpreters](../manual/interpreters.html) using `bin/install-interpreter.sh` command.
+
+### Community managed interpreters
+
+Informations of community managed interpreters are listed in `conf/interpreter-list` file. `bin/install-interpreter.sh` command will read this file to install interpreters.
+
+##### Install all community managed interpreters
+
+```
+./bin/install-interpreter.sh --all
+```
+
+##### Install specific interpreters
+
+```
+./bin/install-interpreter.sh --name md,shell,jdbc,python
+```
+
+You can get full list of community managed interpreters by running
+
+```
+./bin/install-interpreter.sh --list
+```
+
+Once you have installed interpreter, restart Zeppelin. And then you'll need [create interpreter setting](../manual/interpreters.html#what-is-zeppelin-interpreter) and [binding it with your notebook](../manual/interpreters.html#what-is-zeppelin-interpreter-setting).
+
+
+### 3rd party interpreters
+
+`./bin/install-interpreter.sh` command can install 3rd party interpreters available in maven repository.
+
+##### Install 3rd party interpreters
+
+```
+./bin/install-interpreter.sh --name interpreter1 --repository groupId1:artifact1:version1
+```
+
+The command will download maven artifact `groupId1:artifact1:version1` and all of it's transitive dependencies into `interpreter/interpreter1` directory.
+
+Once you have installed interpreters, you'll need to add interpreter class name into `zeppelin.interpreters` property in [configuration](install.html#zeppelin-configuration).
+And then restart Zeppelin, [create interpreter setting](../manual/interpreters.html#what-is-zeppelin-interpreter) and [binding it with your notebook](../manual/interpreters.html#what-is-zeppelin-interpreter-setting).
+
+
+##### Install multiple 3rd party interpreters at once
+
+`--name` and `--repository` argument receives comma separated list
+
+```
+./bin/install-interpreter.sh --name interpreter1,interpreter2 --repository groupId1:artifact1:version1,groupId2:artifact2:version2
