It's a bit outside the scope, but I've tried to go through the instructions on a fresh machine (VM) and I've stumbled on some issues:

---

$ touch .env
$ echo "BASE_URL=https://plausible.example.com" >> .env
$ echo "SECRET_KEY_BASE=$(openssl rand -base64 48)" >> .env

$ cat .env
BASE_URL=https://plausible.example.com
SECRET_KEY_BASE=As0fZsJlUpuFYSthRjT5Yflg/NlxkFKPRro72xMLXF8yInZ60s6xGGXYVqml+XN1

I know it's an example, but I'd replace the secret key string with ellipsis, just in case 🙈

There's a missing indent in the override example. Instead of:

```bash
$ echo "HTTP_PORT=80" >> .env
$ echo "HTTPS_PORT=443" >> .env

$ cat > compose.override.yml << EOF
services:
    plausible:
    ports:
        - 80:80
        - 443:443
EOF

it should be:

```bash
$ echo "HTTP_PORT=80" >> .env
$ echo "HTTPS_PORT=443" >> .env

$ cat > compose.override.yml << EOF
services:
    plausible:
        ports:
            - 80:80
            - 443:443
EOF

---

Perhaps it would make sense to reformat/split snippets (with output examples in separate code blocks) so that they can be copied with a single click instead of selecting manually?

---

The 500 template shows "We have been notified" 😅

@aerosol @zoldar Thanks for checking this!

@zoldar I applied the fixes that you mentioned
#271

Perhaps it would make sense to reformat/split snippets (with output examples in separate code blocks) so that they can be copied with a single click instead of selecting manually?

It's a good idea (there's another PR with that suggestion), and I tried to when posting this PR, but it actually made it harder to read and understand, at least for me. I'm not opposed to it if you want to give it a shot though.
