Installation

The recommended method is using use-package and straight, or a similar package manager.

(use-package org-roam
      :after org
      :hook 
      ((org-mode . org-roam-mode)
       (after-init . org-roam--build-cache-async) ;; optional!
       )
      :straight (:host github :repo "jethrokuan/org-roam" :branch "develop")
      :custom
      (org-roam-directory "/path/to/org-files/")
      :bind
      ("C-c n l" . org-roam)
      ("C-c n t" . org-roam-today)
      ("C-c n f" . org-roam-find-file)
      ("C-c n i" . org-roam-insert)
      ("C-c n g" . org-roam-show-graph))

If not using package.el, you can also clone it into your Emacs directory and add it to your load path:

git clone https://github.com/jethrokuan/org-roam/ ~/.emacs.d/elisp/org-roam

(use-package org-roam
      :after org
      :load-path "elisp/"
      :hook 
      ((org-mode . org-roam-mode)
       (after-init . org-roam--build-cache-async) ;; optional!
       )
      :custom
      (org-roam-directory "/path/to/org-files/")
      :bind
      ("C-c n l" . org-roam)
      ("C-c n t" . org-roam-today)
      ("C-c n f" . org-roam-find-file)
      ("C-c n i" . org-roam-insert)
      ("C-c n g" . org-roam-show-graph))

Or without use-package:

(add-to-list 'load-path "./elisp")
(require 'org-roam)

There are a number of important configuration options, that greatly affect the Roam workflow. Do look through them at the Configuration page.

Spacemacs

If you are using Spacemacs, you can easily install org-roam by creating a simple layer that wraps org-roam. Paste the following into a new file /.emacs.d/private/org-roam/packages.el.

(defconst org-roam-packages
  '((org-roam :location
        (recipe :fetcher github :repo "jethrokuan/org-roam" :branch "develop"))))

(defun org-roam/init-org-roam ()
    (use-package org-roam
        :after org
        :hook
        ((org-mode . org-roam-mode)
         (after-init . org-roam--build-cache-async) ;; optional!
         )
        :custom
        (org-roam-directory "/path/to/org-files/")
        :init
        (progn
          (spacemacs/declare-prefix "ar" "org-roam")
          (spacemacs/set-leader-keys
            "arl" 'org-roam
            "art" 'org-roam-today
            "arf" 'org-roam-find-file
            "arg" 'org-roam-show-graph)

          (spacemacs/declare-prefix-for-mode 'org-mode "mr" "org-roam")
          (spacemacs/set-leader-keys-for-major-mode 'org-mode
            "rl" 'org-roam
            "rt" 'org-roam-today
            "rf" 'org-roam-find-file
            "ri" 'org-roam-insert
            "rg" 'org-roam-show-graph)
          )))

Next, append org-roam to the dotspacemacs-configuration-layers list in your .spacemacs configuration file. Reload (SPC f e R) or restart Emacs to load org-roam. It's functions are available under the prefix SPC a r and , r when visiting an org-mode buffer.
