+# ssh-agent plugin
+
+This plugin starts automatically `ssh-agent` to set up and load whichever
+credentials you want for ssh connections.
+
+To enable it, add `ssh-agent` to your plugins:
+
+```zsh
+plugins=(... ssh-agent)
+```
+
+## Settings
+
+**IMPORTANT: put these settings _before_ the line that sources oh-my-zsh**
+
+To enable **agent forwarding support** add the following to your zshrc file:
+
+```zsh
+zstyle :omz:plugins:ssh-agent agent-forwarding on
+```
+
+----
+
+To **NOT load any identities on start** use the `lazy` setting. This is particularly
+useful when combined with the `AddKeysToAgent` setting (available since OpenSSH 7.2),
+since it allows to enter the password only on first use. _NOTE: you can know your
+OpenSSH version with `ssh -V`._
+
+```zsh
+zstyle :omz:plugins:ssh-agent lazy yes
+```
+
+You can enable `AddKeysToAgent` by passing `-o AddKeysToAgent=yes` to the `ssh` command,
+or by adding `AddKeysToAgent yes` to your `~/.ssh/config` file [1].
+See the [OpenSSH 7.2 Release Notes](http://www.openssh.com/txt/release-7.2).
+
+----
+
+To **load multiple identities** use the `identities` style (**this has no effect
+if the `lazy` setting is enabled**). For example:
+
+```zsh
+zstyle :omz:plugins:ssh-agent identities id_rsa id_rsa2 id_github
+```
+
+**NOTE:** the identities may be an absolute path if they are somewhere other than
+`~/.ssh`. For example:
+
+```zsh
+zstyle :omz:plugins:ssh-agent identities ~/.config/ssh/id_rsa ~/.config/ssh/id_rsa2 ~/.config/ssh/id_github
+# which can be simplified to
+zstyle :omz:plugins:ssh-agent identities ~/.config/ssh/{id_rsa,id_rsa2,id_github}
+```
+
+----
+
+To **set the maximum lifetime of the identities**, use the `lifetime` style.
+The lifetime may be specified in seconds or as described in sshd_config(5)
+(see _TIME FORMATS_). If left unspecified, the default lifetime is forever.
+
+```zsh
+zstyle :omz:plugins:ssh-agent lifetime 4h
+```
+
+----
+
+To **pass arguments to the `ssh-add` command** that adds the identities on startup,
+use the `ssh-add-args` setting. You can pass multiple arguments separated by spaces:
+
+```zsh
+zstyle :omz:plugins:ssh-agent ssh-add-args -K -c -a /run/user/1000/ssh-auth
+```
+
+These will then be passed the the `ssh-add` call as if written directly. The example
+above will turn into:
+
+```zsh
+ssh-add -K -c -a /run/user/1000/ssh-auth <identities>
+```
+
+For valid `ssh-add` arguments run `ssh-add --help` or `man ssh-add`.
+
+----
+
+To set an **external helper** to ask for the passwords and possibly store
+them in the system keychain use the `helper` style. For example:
+
+```zsh
+zstyle :omz:plugins:ssh-agent helper ksshaskpass
+```
