Which does 3 jobs: The installer will perform 3 actions:
* create and copy `acme.sh` to your home dir: `~/.acme.sh/`
All the certs will be placed in this folder.
* create alias : `acme.sh=~/.acme.sh/acme.sh`.
* create everyday cron job to check and renew the cert if needed.
After install, you must close current terminal and reopen again to make the alias take effect. 1. Create and copy `acme.sh` to your home dir (`$HOME`): `~/.acme.sh/`.
All certs will be placed in this folder.
2. Create alia for: `acme.sh=~/.acme.sh/acme.sh`.
3. Create everyday cron job to check and renew the cert if needed.
Cron entry example:
```bash
0 0 * * * "/home/user/.acme.sh"/acme.sh --cron --home "/home/user/.acme.sh" > /dev/null
```
After the installation, you must close current terminal and reopen again to make the alias take effect.
