 ## Requirements
 
-If installing from source, Git is required. You can install Git using the `geerlingguy.git` role.
+If installing from source (deprecated), Git is required. You can install Git using the `geerlingguy.git` role.
 
-Generally, installing from source (see section `Source Installation from Git`) leads to a better experience using Certbot and Let's Encrypt, especially if you're using an older OS release.
+For the `pip` install method, only Debian-family targets are supported (apt is used for the `python3-venv` / `libaugeas-dev` / `gcc` prerequisites).
+
+If you want an always-latest Certbot install on modern distros, prefer `pip` (see `Pip Installation` below) over `source` — the legacy source method relies on `certbot-auto`, which EFF removed from the Certbot repo in 2021.

-### Source Installation from Git
+### Pip Installation
+
+Setting `certbot_install_method: pip` installs Certbot into a Python virtual environment at `{{ certbot_dir }}` (default `/opt/certbot`) using EFF's recommended pip install path: <https://certbot.eff.org/instructions?os=pip>. The `certbot` binary is symlinked into `/usr/local/bin` so it is on `PATH`.
+
+This is the modern equivalent of the legacy `source` install — use it when you want an always-latest Certbot on a distro whose packaged version is too old. Only Debian-family targets are supported by the included tasks; the necessary apt prerequisites (`python3-venv`, `libaugeas-dev`, `gcc`, etc.) are installed automatically.

 You can install Certbot from it's Git source repository if desired with `certbot_install_method: source`. This might be useful in several cases, but especially when older distributions don't have Certbot packages available (e.g. CentOS < 7, Ubuntu < 16.10 and Debian < 8).

 ### Wildcard Certificates
 
 Let's Encrypt supports [generating wildcard certificates](https://community.letsencrypt.org/t/acme-v2-and-wildcard-certificate-support-is-live/55579), but the process for generating and using them is slightly more involved. See comments in [this pull request](https://github.com/geerlingguy/ansible-role-certbot/pull/60#issuecomment-423919284) for an example of how to use this role to maintain wildcard certs.
