Siapics
=======
Install
-------
First, you need to install Sia and execute `siad`. After block synchronization is complete (check with `siac` command),
you have to put some Sia coins into the wallet, and unlock the wallet.
https://github.com/dvstate/minio#install-sia-daemon
When this is all done, you are ready to set up Minio. Execute the following commands:
```
MINIO_ACCESS_KEY=*username*
MINIO_SECRET_KEY=*password*
minio gateway sia
```
Now, install siapics on the server, and execute `siapics --minio-user *username* --minio-password *password*`. It will
listen on `http://localhost:9191`. To access siapics from another device, you need to set up a proxy server, like Nginx.
You can browse the existing files at `http://localhost:9000`, with the above username and password.
