-</details>
 
-### Using `straight.el`
+Org-roam requires sqlite to function. Org-roam optionally uses Graphviz for
-<details>
+graph-related functionality. It is recommended to install PCRE-enabled ripgrep
-<summary>Toggle instuctions</summary>
+for better performance and extended functionality.
-
-Installation from MELPA or MELPA Stable using `straight.el`:
-
-```emacs-lisp
-(straight-use-package 'org-roam)
-```
-
-Or with `use-package`:
-
-```emacs-lisp
-(use-package org-roam
-  :straight t
-  ...)
-```
-
-If you need to install the package directly from the source repository, instead
-of from MELPA, the next sample shows how to do so:
-
-```emacs-lisp
-(use-package org-roam
-  :straight (:host github :repo "org-roam/org-roam"
-             :files (:defaults "extensions/*"))
-  ...)
-```
-
-If you plan to use your own local fork for the development and contribution, the
-next sample will get you there:
-
-```emacs-lisp
-(use-package org-roam
-  :straight (:local-repo "/path/to/org-roam-fork"
-             :files (:defaults "extensions/*")
-             :build (:not compile))
-  ...)
-```
-</details>
-
-### Using Doom Emacs
-<details>
-<summary>Toggle instuctions</summary>
-
-Doom's `:lang org` module comes with support for `org-roam`, but it's not
-enabled by default. To activate it pass `+roam2` flag to `org` module in your
-`$DOOMDIR/init.el` (e.g. `(org +roam2)`), save the file and run `doom sync -u`
-in your shell.
-
-To provide better stability, Doom pins the package to a specific commit. If you
-need to unpin it *(not recommended doing that, request Doom to bump the package
-instead)* use the next in your `packages.el`:
-
-```emacs-lisp
-(unpin! org-roam)
-```
-
-If for some reasons you want to use a different recipe for `org-roam`, you can
-use the next form in your `packages.el` to install the package from a recipe
-repository (e.g. MELPA):
-
-```emacs-lisp
-(package! org-roam)
-```
-
-You can pass `:pin "commit hash"` to pin the package to a specific commit.
-
-With the next sample you can install the package directly from the source
-repository:
-
-```emacs-lisp
-(package! org-roam
-  :recipe (:host github :repo "org-roam/org-roam"
-           :files (:defaults "extensions/*")))
-```
-
-And if you plan to use your own local fork for the development or contribution,
-the next sample will get you there:
-
-```emacs-lisp
-(package! org-roam
-  :recipe (:local-repo "/path/to/org-roam-fork"
-           :files (:defaults "extensions/*")
-           :build (:not compile)))
-```
-</details>
-
-### Without a package manager
-<details>
-<summary>Toggle instructions</summary>
-
-To install the package without using a package manager you have the next two
-options:
-
-1. Install the package by cloning it with `git` from the source repository.
-2. Or install the package by downloading the latest [release
-   version](https://github.com/org-roam/org-roam/releases).
-   
-In both of the cases you will need to ensure that you have all the required
-dependencies. These include:
-
-- dash
-- f
-- s
-- org (9.4 is the minimal required version!)
-- emacsql
-- emacsql-sqlite
-- magit-section
-- filenotify-recursive
-
-After installing the package, you will need to properly setup `load-path` to the
-package:
-
-``` emacs-lisp
-(add-to-list 'load-path "/path/to/org-roam/")
-(add-to-list 'load-path "/path/to-org-roam/extensions/")
-```
-
-After which you should be able to resolve `(require 'org-roam)` call without any
-problems.
-
-Org-roam also comes with `.texi` files to integrate with Emacs' built-in Info
-system. Read the manual to find more details for how to install them manually.
