+# Dotfiles
+
+Coder offers the `coder dotfiles <repo>` command which simplifies workspace
+personalization. Our behavior is consistent with Codespaces, so
+[their documentation](https://docs.github.com/en/codespaces/customizing-your-codespace/personalizing-codespaces-for-your-account#dotfiles)
+explains how it loads your repo.
+
+You can read more on dotfiles best practices [here](https://dotfiles.github.io).
+
+## Templates
+
+Templates can prompt users for their dotfiles repo using the following pattern:
+
+```hcl
+variable "dotfiles_uri" {
+  description = <<-EOF
+  Dotfiles repo URI (optional)
+
+  see https://dotfiles.github.io
+  EOF
+    # The codercom/enterprise-* images are only built for amd64
+  default = ""
+}
+
+resource "coder_agent" "dev" {
+  ...
+  startup_script = var.dotfiles_uri != "" ? "/tmp/tmp.coder*/coder dotfiles -y ${var.dotfiles_uri}" : null
+}
+```
+
+[Here's a complete example.](https://github.com/coder/coder/tree/main/examples/templates/docker-with-dotfiles#how-it-works)
+
+## Persistent Home
+
+Sometimes you wants to support personalization without
+requiring dotfiles.
+
+In such cases:
+
+- Mount a persistent volume to the `/home` directory
+- Set the `startup_script` to call a `~/personalize` script that the user can edit
+
+```hcl
+resource "coder_agent" "dev" {
+  ...
+  startup_script = "/home/coder/personalize"
+}
+```
+
+The user can even fill `personalize` with `coder dotfiles <repo>`, but those
+looking for a simpler approach can inline commands like so:
+
+```bash
+#!/bin/bash
+sudo apt update
+# Install some of my favorite tools every time my workspace boots
+sudo apt install -y neovim fish cargo
+```
