> Logseq web app uses [File System Access API](https://developer.mozilla.org/en-US/docs/Web/API/File_System_Access_API) to access the file system. You need a [compatible browser](https://caniuse.com/native-filesystem-api).
> Also, an HTTPS connection is required if you are accessing it remotely.
Here we use the [mkcert](https://github.com/FiloSottile/mkcert) to generate locally-trusted development certificates. For other purposes, you should apply a certificate from a trusted CA.
Suppose you are deploying the web app to 192.168.11.95.
### Install mkcert(web app of Filesystem API requires HTTPS)
```shell
# macOS
brew install mkcert
# or archlinux
sudo pacman -Ss mkcert
# or follow the install instructions from https://github.com/FiloSottile/mkcert
```
### Install mkcert root CA
```shell
mkcert -install
```
### Prepare SSL cert
```shell
mkcert 192.168.11.95 # public IP address or hostname of the remote machine
