 ## Technologies used
 
-### [NixOS](https://nixos.org/)
+This is an incomplete and evolving list of core components planned to be used in this project.
+It will grow to support more advanced use cases as the framework matures.
+
+### Nix and [NixOS](https://nixos.org/)
 
 NixOS is a Linux distribution with a [vibrant](https://repology.org/repositories/graphs), [reproducible](https://reproducible.nixos.org/) and [security-conscious](https://tracker.security.nixos.org/) ecosystem.
 As such, we see NixOS as the only viable way to reliably create a reproducible outcome for all the work we create.
@@ -94,35 +97,6 @@ Considered alternatives include:
 
 - containers: do not by themselves offer the needed reproducibility
 
-#### [npins](https://github.com/andir/npins)
-
-Npins is a dependency pinning tool for Nix which leaves recursive dependencies explicit, keeping the consumer in control.
-
-Considered alternatives include:
-
-- Flakes: defaults to implicitly following recursive dependencies, leaving control with the publisher.
-
-### [SelfHostBlocks](https://nlnet.nl/project/SelfHostBlocks/)
-
-SelfHostBlocks offers Nix module contracts to decouple application configuration from implementation details, empowering user choice by providing sane defaults yet a [unified interface](https://nlnet.nl/project/SelfHostBlocks/).
-Offered contracts include back-ups, reverse proxies, single sign-on and LDAP.
-In addition, we have been in contact with its creator.
-
-Considered alternatives include:
-
-- nixpkgs-provided NixOS service modules: support far more applications, but tightly coupled with service providers, whereas we expect them to [sooner or later](https://discourse.nixos.org/t/pre-rfc-decouple-services-using-structured-typing/58257) follow suit.
-- NixOS service modules curated from scratch: would support any setup imaginable, but does not seem to align as well with our research-oriented goals.
-
-### [OpenTofu](https://opentofu.org/)
-
-OpenTofu is the leading open-source framework for infrastructure-as-code.
-This has led it to offer a vibrant ecosystem of 'provider' plugins integrating various programs and services.
-As such, it can facilitate automated deployment pipelines, including with — relevant to our project — hypervisors and DNS programs.
-
-Considered alternatives include:
-
-- Terraform: not open-source
-
 ### [Proxmox](https://proxmox.com/)
 
 Proxmox is a hypervisor, allowing us to create VMs for our applications while adhering to our goal of preventing lock-in.
@@ -141,68 +115,6 @@ Considered alternatives include:
 
 - file storage: less centralized for backups
 
-### [PostgreSQL](https://www.postgresql.org/)
-
-PostgreSQL is a relational database.
-It is used by most of our applications.
-
-Considered alternatives include:
-
-- Sqlite: default option for development in many applications, but less optimized for performance, and less centralized for backups
-
-### [Valkey](https://valkey.io/)
-
-Valkey is a key-value store.
-It is an open-source fork of Redis.
-
-Considered alternatives include:
-
-- Redis: not open-source
-
-### [OpenSearch](https://opensearch.org/)
-
-OpenSearch offers full-text search, and is used for this in many applications.
-It is an open-source fork of ElasticSearch.
-
-Considered alternatives include:
-
-- ElasticSearch: not open-source
-
-### [OctoDNS](https://github.com/octodns/octodns)
-
-OctoDNS is a DNS server that may be configured using the Nix-native [NixOS-DNS](https://janik-haag.github.io/NixOS-DNS/).
-
-Considered alternatives include:
-
-- PowerDNS: offers a front-end option, but less geared toward the use-case of configuring by Nix
-
-### [Authelia](https://github.com/authelia/authelia)
-
-Authelia is a single sign-on provider that integrates with LDAP.
-
-Considered alternatives include:
-
-- KaniDM: does not do proper LDAP
-- Authentik: larger package with focus on many things we do not need
-- Keycloak: larger package with focus on many things we do not need
-
-### [lldap](https://github.com/lldap/lldap)
-
-Lldap is a light LDAP server, allowing to centralize user roles across applications.
-
-Considered alternatives include:
-
-- 389 DS: older larger package
-- FreeIPA: wrapper around 389 DS
-
-### [Attic](https://github.com/zhaofengli/attic)
-
-Attic is a multi-tenant Nix cache featuring recency-based garbage collection written in Rust.
-
-Considered alternatives include:
-
-- cache-server: distributed cache written in Python that seems more of a research project than an actively maintained repository.
