 6### Setup
 7
 8Zed currently doesn't install Solargraph automatically. To use Solargraph, you need to install the gem. Zed just looks for an executable called `solargraph` on your `PATH`.
 9
10You can install the gem manually with the following command:
11
12```shell
13gem install solargraph
14```
15
16Alternatively, if your project uses Bundler, you can add the Solargraph gem to your `Gemfile`:
17
18```ruby
19gem 'solargraph', group: :development
20```
21
22Solargraph has formatting and diagnostics disabled by default. We can tell Zed to enable them by adding the following to your `settings.json`:
23
24```json
25{
26  "lsp": {
27    "solargraph": {
28      "initialization_options": {
29        "diagnostics": true,
30        "formatting": true
31      }
32    }
33  }
34}
35```
36
37### Configuration
38
39Solargraph reads its configuration from a file called `.solargraph.yml` in the root of your project. For more information about this file, see the [Solargraph configuration documentation](https://solargraph.org/guides/configuration).
