-> For automatic Papirus folder icon color syncing, `papirus-folders` needs to be able to run with `sudo` without a password prompt.
-> 
-> **Recommended** - Create a sudoers file:
-> ```fish
-> # Fish shell
-> echo "$USER ALL=(ALL) NOPASSWD: "(which papirus-folders) | sudo tee /etc/sudoers.d/papirus-folders
-> sudo chmod 440 /etc/sudoers.d/papirus-folders

-> sudo chmod 440 /etc/sudoers.d/papirus-folders
-> ```
-> 
-> **Alternatively** - Edit the main sudoers file by running `sudo visudo` and adding at the end:
-> ```
-> your_username ALL=(ALL) NOPASSWD: /usr/bin/papirus-folders

+### Additional steps
+
+#### Auto folder colour theming
+
+For automatic Papirus folder icon colour syncing, you must have [`papirus-folders`](https://github.com/PapirusDevelopmentTeam/papirus-folders)
+installed, and `papirus-folders` must to be able to run with `sudo` without a password prompt.
+
+You can allow this by creating a sudoers file:
+
+```sh
+echo "$USER ALL=(ALL) NOPASSWD: $(which papirus-folders)" | sudo tee /etc/sudoers.d/papirus-folders
+sudo chmod 440 /etc/sudoers.d/papirus-folders
+```
+
+#### Chromium-based browser theming
+
+For live Chromium-based browser theming, the CLI must be allowed to create certain directories in `/etc`
+and write to them via `sudo` without a password prompt.
+
+You can allow this by creating a sudoers file:
+
+```fish
+# Fish shell
+for dir in /etc/chromium/policies/managed /etc/brave/policies/managed /etc/opt/chrome/policies/managed
+    echo "$USER ALL=(ALL) NOPASSWD: $(which mkdir) -p $dir" | sudo tee -a /etc/sudoers.d/caelestia-chromium
+    echo "$USER ALL=(ALL) NOPASSWD: $(which tee) $dir/caelestia.json" | sudo tee -a /etc/sudoers.d/caelestia-chromium
+end
+sudo chmod 440 /etc/sudoers.d/caelestia-chromium
+```
+
+```sh
+# Bash/other shells
+for dir in /etc/chromium/policies/managed /etc/brave/policies/managed /etc/opt/chrome/policies/managed; do
+    echo "$USER ALL=(ALL) NOPASSWD: $(which mkdir) -p $dir" | sudo tee -a /etc/sudoers.d/caelestia-chromium

+### User templates
+
+Custom user templates can be defined in `~/.config/caelestia/templates/`.
+
+#### Template syntax
+
+`{{ <color>.<format> }}`
+
+- `<color>` is a theme color role derived from the Material You color system (e.g. `primary`, `secondary`, `background`)
+- `<format>` is the output format: `hex` or `rgb`
+
+#### Examples
+
+- `{{ primary.hex }}` outputs `3f4ba2`
+- `{{ primary.rgb }}` outputs `rgb(193, 132, 207)`
+
+Output files are written to `~/.local/state/caelestia/theme/`. You can symlink them to your desired locations.
