# Configuration
You can choose to configure HedgeDoc with either a config file or with environment variables.
Environment variables take precedence over configurations from the config files. They generally start with `CMD_` for our own options, but we also list node-specific options you can configure this way.
- Environment variables are processed in [`lib/config/environment.js`](https://github.com/hedgedoc/hedgedoc/tree/master/lib/config/environment.js) - so this is the first place to look if anything is missing not obvious from this document. The default values are defined in [`lib/config/default.js`](https://github.com/hedgedoc/hedgedoc/tree/master/lib/config/default.js), in case you wonder if you even need to override it.
- The config file is processed in [`lib/config/index.js`](https://github.com/hedgedoc/hedgedoc/tree/master/lib/config/index.js) - so this is the first place to look if anything is missing not obvious from this document. The default values are defined in [`lib/config/default.js`](https://github.com/hedgedoc/hedgedoc/tree/master/lib/config/default.js), in case you wonder if you even need to override it. To get started, it is a good idea to take the [`config.json.example`](https://github.com/hedgedoc/hedgedoc/tree/master/config.json.example) and copy it
to `config.json` before filling in your own details.
**Note:** *Due to the rename process we renamed all `HMD_`-prefix variables to be `CMD_`-prefixed. The old ones continue to work.*

| `csp` | | `{"enable": true, "addDefaults": true}` | Nested object to configure the Content Security Policy |
| `csp.enable` | `CMD_CSP_ENABLE` | **`true`** or `false` | Whether to apply a `Content-Security-Policy` header to responses. We don't recommend disabling this option, as it significantly reduces the security of the application. |
| `csp.addDefaults` | | **`true`** or `false` | Disable to not include the default CSP. Be careful, this will break the application if the correct directives are not set manually. |
| `csp.directives` | | **no default**, `{"scriptSrc": "trustworthy-scripts.example.com"}` | Custom CSP directives. These are passed to Helmet - see [their documentation](https://helmetjs.github.io/docs/csp/) for more information on the format. |
| `csp.addDisqus` | `CMD_CSP_ADD_DISQUS` | **`false`** or `true` | Enable to allow users to add Disqus comments to their notes or presentations. We don't recommend enabling this option, as it increases the attack surface of XSS attacks. |
| `csp.addGoogleAnalytics` | `CMD_CSP_ADD_GOOGLE_ANALYTICS` | **`false`** or `true` | Enable to allow users to add Google Analytics to their notes. We don't recommend enabling this option, as it increases the attack surface of XSS attacks. |

| `csp.allowFraming` | `CMD_CSP_ALLOW_FRAMING` | **`true`** or `false` | Disable to disallow embedding of the instance via iframe. We **strongly recommend disabling** this option, as it increases the attack surface of XSS attacks. |
| `csp.allowPDFEmbed` | `CMD_CSP_ALLOW_PDF_EMBED` | **`true`** or `false` | Disable to disallow embedding PDFs. We recommend disabling this option, as it increases the attack surface of XSS attacks. |
| `cookiePolicy` | `CMD_COOKIE_POLICY` | **`lax`**, `strict` or `none` | Set a SameSite policy whether cookies are send from cross-origin. Be careful: setting a SameSite value of none without https breaks the editor. |
## Privacy and External Requests

| `requireFreeURLAuthentication` | `CMD_REQUIRE_FREEURL_AUTHENTICATION` | **`false`** or `true` | Set to require authentication for FreeURL mode style note creation. |
| `defaultPermission` | `CMD_DEFAULT_PERMISSION` | **`editable`**, `freely`, `limited`, `locked`, `protected` or `private` | Set notes default permission (only applied on signed-in users). |
