+#### Default architecture
+
+Packages will be compiled for the architecture of the device running
+pmbootstrap by default. For example, if your `x86_64` PC runs pmbootstrap, it
+would build a package for `x86_64` with this command:
+```
+$ pmbootstrap build hello-world
+```
+
+If you would rather build for the target device selected in `pmbootstrap init`
+by default, then use the `build_default_device_arch` option:
+```
+$ pmbootstrap config build_default_device_arch True
+```
+
+If your target device is `pine64-pinephone` for example, pmbootstrap will now
+build this package for `aarch64`:

+### Use alternative sudo
 
-## Development
-### Testing
-Install `pytest` (via your package manager or pip) and run it inside the pmbootstrap folder.
+pmbootstrap supports `doas` and `sudo`.
+If multiple sudo implementations are installed, pmbootstrap will use `doas`.
+You can set the `PMB_SUDO` environmental variable to define the sudo
+implementation you want to use.
+
+### Select SSH keys to include and make authorized in new images
+
+If the config file option `ssh_keys` is set to `True` (it defaults to `False`),
+then all files matching the glob `~/.ssh/id_*.pub` will be placed in
+`~/.ssh/authorized_keys` in the user's home directory in newly-built images.
+
+Sometimes, for example if you have a large number of SSH keys, you may wish to
+select a different set of public keys to include in an image. To do this, set
+the `ssh_key_glob` configuration parameter in the pmbootstrap config file to a
+string containing a glob that is to match the file or files you wish to
+include.
+
+For example, a `~/.config/pmbootstrap.cfg` may contain:
+
+    [pmbootstrap]
+    # ...
+    ssh_keys = True
+    ssh_key_glob = ~/.ssh/postmarketos-dev.pub
+    # ...

-    This file sets up an SSH server in the native chroot, which will then be
-    used by the foreign arch chroot to communicate with the distcc daemon. We
-    make sure that only the foreign arch chroot can connect to the sshd by only
-    listening on localhost, as well as generating dedicated ssh keys.
-
-    Using the SSH server instead of running distccd directly is a security
-    measure. Distccd does not authenticate its clients and would therefore
-    allow any process of the host system (not related to pmbootstrap) to
-    execute compilers in the native chroot. By modifying the compiler's options
-    or sending malicious data to the compiler, it is likely that the process
-    can gain remote code execution [1]. That way, a compromised, but sandboxed
-    process could gain privilege escalation.
