+
+### Modules
+
+1.  `acme-sh`
+
+    -   source code: <nixos/modules/acme-sh.nix>
+    
+    Modified version of module originally from [Serokell](https://github.com/serokell/serokell.nix/blob/master/modules/acme-sh.nix). It allows to easy fetch and access certificates, facilitated by \`acme-sh\`. Can be used in tandem with any program which can load certificates from files.
+
+2.  `grafana`
+
+    -   source code: <nixos/modules/grafana.nix>
+    
+    Very simplified version of module originally from [nixpkgs](https://github.com/NixOS/nixpkgs/blob/nixos-24.05/nixos/modules/services/monitoring/grafana.nix).
+    
+    This module is currently **unused**, **untested**, and may be removed or completely reworked soon.
+
+3.  `hashicorp-envoy`
+
+    -   source code: <nixos/modules/hashicorp-envoy.nix>
+    
+    Allows deploying Envoy proxies that can integrate with the Consul Connect service mesh. Used to hook klipper into the rest of my infrastructure.
+    
+    This module is **deprecated** and **will** be removed soon. I'm switching away from Hashicorp Nomad+Consul and towards k3s+Istio and therefore won't have a need for this module.
+
+4.  `hashicorp`
+
+    -   source code: <nixos/modules/hashicorp.nix>
+    
+    Runs Hashicorp Vault, Consul and Nomad. Would probably work with OpenBao too, but this has not yet been tested.
+
+5.  `influx-provisioning`
+
+    -   source code: <nixos/modules/influx-provisioning.nix>
+    
+    Crudely provisions InfluxDB.
+    
+    This module is **deprecated** and **will** be removed soon. It was originally created when I thought I would be switching away from Terraform completely. Now I know I will be switching to OpenTofu.
+
+6.  `microvm-extras-host` and `microvm-extras`
+
+    -   source code: <nixos/modules/microvm-extras-host.nix>, <nixos/modules/microvm-extras.nix>
+    
+    Intended to somewhat simulate a service mesh using `microvm.nix` and clever `nftable` rules. Turned out to be too much work and both will be **removed**.
+
+7.  `netboot-xyz`
+
+    -   source code: <nixos/modules/netboot-xyz.nix>
+    
+    Adds `netboot.xyz` to GRUB, supports both EFI and BIOS. Used on my server in case of catastrophic root pool failure.
+
+8.  `notify-login`
+
+    -   source code: <nixos/modules/notify-login.nix>
+    
+    Send notifications over Matrix, when an SSH session is opened/closed.
+
+9.  `notnft`
+
+    -   source code: <nixos/modules/notnft.nix>
+    
+    Alternative implementation of upstream [notnft](https://github.com/chayleaf/notnft) module, which is part of the much larger [nixos-router](https://github.com/chayleaf/nixos-router) repository.
+
+10. `notnft-ns`
+
+    -   source code: <nixos/modules/notnft-ns.nix>
+    
+    Newer implementation of the [notnft](#org788f38d) module, this one supports network namespaces.
+
+11. `telegraf`
+
+    -   source code: <nixos/modules/telegraf.nix>
+    
+    Very simplified version of module originally from [nixpkgs](https://github.com/NixOS/nixpkgs/blob/nixos-24.05/nixos/modules/services/monitoring/telegraf.nix).
+    
+    This module is currently **unused**, **untested**, and may be removed or completely reworked soon.
