# Configuration Cheat Sheet

This is a cheat sheet for the Gitea configuration file. It contains most of the settings
that can be configured as well as their default values.

Any changes to the Gitea configuration file should be made in `custom/conf/app.ini`
or any corresponding location. When installing from a distribution, this will
typically be found at `/etc/gitea/conf/app.ini`.

The defaults provided here are best-effort (not built automatically). They are
accurately recorded in [app.example.ini](https://github.com/go-gitea/gitea/blob/master/custom/conf/app.example.ini)
(s/master/\<tag|release\>). Any string in the format `%(X)s` is a feature powered
by [ini](https://github.com/go-ini/ini/#recursive-values), for reading values recursively.

Values containing `#` or `;` must be quoted using `` ` `` or `"""`.

**Note:** A full restart is required for Gitea configuration changes to take effect.

## Overall (`DEFAULT`)

- `APP_NAME`: **Gitea: Git with a cup of tea**: Application name, used in the page title.
- `RUN_USER`: **git**: The user Gitea will run as. This should be a dedicated system
   (non-user) account. Setting this incorrectly will cause Gitea to not start.
- `RUN_MODE`: **prod**: Application run mode, affects performance and debugging. Either "dev", "prod" or "test".

## Repository (`repository`)

- `ROOT`: **data/gitea-repositories/**: Root path for storing all repository data. It must be
   an absolute path. By default it is stored in a sub-directory of `APP_DATA_PATH`.
- `SCRIPT_TYPE`: **bash**: The script type this server supports. Usually this is `bash`,
   but some users report that only `sh` is available.
- `DETECTED_CHARSETS_ORDER`: **UTF-8, UTF-16BE, UTF-16LE, UTF-32BE, UTF-32LE, ISO-8859, windows-1252, ISO-8859, windows-1250, ISO-8859, ISO-8859, ISO-8859, windows-1253, ISO-8859, windows-1255, ISO-8859, windows-1251, windows-1256, KOI8-R, ISO-8859, windows-1254, Shift_JIS, GB18030, EUC-JP, EUC-KR, Big5, ISO-2022, ISO-2022, ISO-2022, IBM424_rtl, IBM424_ltr, IBM420_rtl, IBM420_ltr**: Tie-break order of detected charsets - if the detected charsets have equal confidence, charsets earlier in the list will be chosen in preference to those later. Adding `defaults` will place the unnamed charsets at that point.

RENDER_COMMAND = "asciidoc --out-file=- -"
IS_INPUT_FILE = false
```

- `GITEA_PREFIX_RAW`, which contains the current URL prefix in the `raw` path tree. To be used as prefix for image paths.


Gitea supports customizing the sanitization policy for rendered HTML. The example below will support KaTeX output from pandoc.

```ini
[markup.sanitizer.TeX]

; with "inline" or "display" classes depending on context.
ELEMENT = span
ALLOW_ATTR = class
REGEXP = ^\s*((math(\s+|$)|inline(\s+|$)|display(\s+|$)))+
```

And you can also define a customize storage like below:

```ini

STORAGE_TYPE = minio
; Minio endpoint to connect only available when STORAGE_TYPE is `minio`
MINIO_ENDPOINT = localhost:9000
; Minio accessKeyID to connect only available when STORAGE_TYPE is `minio`
MINIO_ACCESS_KEY_ID =
