| # Development | ||
|
|
||
| ## Setup | ||
|
|
||
| 1. Install dependencies listed in [README.md](https://github.com/nandesh-dev/subtle/blob/main/README.md) or [shell.nix](https://github.com/nandesh-dev/subtle/blob/main/shell.nix) | ||
|
|
||
| 2. Generate protobuf files | ||
|
|
||
| ```bash | ||
| make proto | ||
| ``` | ||
|
|
||
| 3. Run go | ||
|
|
||
| ```bash | ||
| go run ./cmd/subtle | ||
| ``` | ||
|
|
||
| ## Docker Image | ||
|
|
||
| ### Volumes | ||
|
|
||
| |Path|Use| | ||
| |---|---| | ||
| |`/media`|Directory where all your media content is stored| | ||
| |`/config`|Directory where all the subtle data will be stored| | ||
