You can choose to configure CodiMD 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`](../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`](../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`](../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`](../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` and copy it
to `config.json` before filling in your own details.
| `allowPDFExport` | `CMD_ALLOW_PDF_EXPORT` | `true` or `false` | Enable or disable PDF exports |
| | `CMD_CONFIG_FILE` | `/path/to/config.json` | optional override for the path to CodiMD's config file |
| `db` | | `{ "dialect": "sqlite", "storage": "./db.codimd.sqlite" }` | set the db configs, [see more here](http://sequelize.readthedocs.org/en/latest/api/sequelize/) |
| `dbURL` | `CMD_DB_URL` | `mysql://localhost:3306/database` | Set the db in URL style. If set, then the relevant `db` config entries will be overridden. |
| `loglevel` | `CMD_LOGLEVEL` | `info`, `debug` ... | Defines what kind of logs are provided to stdout. Available options: `debug`, `verbose`, `info`, `warn`, `error` |
| `forbiddenNoteIDs` | `CMD_FORBIDDEN_NOTE_IDS` | `['robots.txt']` or `'robots.txt'` | disallow creation of notes, even if `allowFreeUrl` or `CMD_ALLOW_FREEURL` is `true` |
| `imageUploadType` | `CMD_IMAGE_UPLOAD_TYPE` | `imgur`, `s3`, `minio`, `azure`, `lutim` or `filesystem` (default) | Where to upload images. For S3, see our Image Upload Guides for [S3](guides/s3-image-upload.md) or [Minio](guides/minio-image-upload.md), also there's a whole section on their respective env vars below. |
| `sourceURL` | `CMD_SOURCE_URL` | `https://github.com/codimd/server/tree/<current commit>` | Provides the link to the source code of CodiMD on the entry page (Please, make sure you change this when you run a modified version) |
| `tooBusyLag` | `CMD_TOOBUSY_LAG` | `70` | CPU time for one event loop tick until node throttles connections. (milliseconds) |

| `protocolUseSSL` | `CMD_PROTOCOL_USESSL` | `true` or `false` | set to use SSL protocol for resources path (only applied when domain is set) |
| `useSSL` | | `true` or `false` | set to use SSL server (if `true`, will auto turn on `protocolUseSSL`) |

## CSP and HSTS
| config file | environment | example value | description |
| `hsts` | | `{"enable": true, "maxAgeSeconds": 31536000, "includeSubdomains": true, "preload": true}` | [HSTS](https://en.wikipedia.org/wiki/HTTP_Strict_Transport_Security) options to use with HTTPS (default is the example value, max age is a year) |
| | `CMD_HSTS_ENABLE` | ` true` | set to enable [HSTS](https://en.wikipedia.org/wiki/HTTP_Strict_Transport_Security) if HTTPS is also enabled (default is ` true`) |
| `csp` | | `{"enable": true, "directives": {"scriptSrc": "trustworthy-scripts.example.com"}, "upgradeInsecureRequests": "auto", "addDefaults": true}` | Configures [Content Security Policy](https://helmetjs.github.io/docs/csp/). Directives are passed to Helmet - see [their documentation](https://helmetjs.github.io/docs/csp/) for more information on the format. Some defaults are added to the configured values so that the application doesn't break. To disable this behaviour, set `addDefaults` to `false`. Further, if `usecdn` is on, some CDN locations are allowed too. By default (`auto`), insecure (HTTP) requests are upgraded to HTTPS via CSP if `useSSL` is on. To change this behaviour, set `upgradeInsecureRequests` to either `true` or `false`. |
| | `CMD_CSP_ENABLE` | `true` | whether to enable Content Security Policy (directives cannot be configured with environment variables) |
| `allowGravatar` | `CMD_ALLOW_GRAVATAR` | `true` or `false` | set to `false` to disable [Libravatar](https://www.libravatar.org/) as profile picture source on your instance. Libravatar is a federated open-source alternative to Gravatar. |

| `allowFreeURL` | `CMD_ALLOW_FREEURL` | `true` or `false` | Set to allow new note creation by accessing a nonexistent note URL. This is the behavior familiar from [Etherpad](https://github.com/ether/etherpad-lite). |
| `defaultPermission` | `CMD_DEFAULT_PERMISSION` | `freely`, `editable`, `limited`, `locked`, `protected` or `private` | Set notes default permission (only applied on signed-in users). |
