+# Packages
+
+## Why? What have you done to suffer so much?
+Idk any other ways to let all users access individual package managers, so you'll have to use Nix. Sorry
+
+## How?
+I installed nix-env which is available for every user, but it has disgusting commands, so I suggest bash and fish users paste this
+functions into their respective `~/.bashrc` and `~/.config/fish/config.fish`:
+
+```bash
+function nix-install {
+    nix-env -iA "$@" 2>&1 | grep -v 'evaluation warning'
+}
+function nix-remove {
+    nix-env -e "$@" 2>&1 | grep -v 'evaluation warning'
+}
+function nix-upgrade {
+    nix-env --upgrade 2>&1 | grep -v 'evaluation warning'
+}
+function nix-rollback {
+    nix-env --rollback 2>&1 | grep -v 'evaluation warning'
+}
+function nix-list {
+    nix-env -q 2>&1 | grep -v 'evaluation warning'
+}
+```
+
+```fish
+function nix-install
+    nix-env -iA $argv 2>&1 | grep -v 'evaluation warning'
+end
+function nix-remove
+    nix-env -e $argv 2>&1 | grep -v 'evaluation warning'
+end
+function nix-upgrade
+    nix-env --upgrade 2>&1 | grep -v 'evaluation warning'
+end
+function nix-rollback
+    nix-env --rollback 2>&1 | grep -v 'evaluation warning'
+end
+function nix-list
+    nix-env -q 2>&1 | grep -v 'evaluation warning'
+end

+# Podman
+
+## Why?
+On that server we use podman instead of docker because it's:
+- rootless by default
+- individual for each user (you won't be able to access container of other person)
+- have preinstalled k8s (which is called pod and idk why it's needed for us but it's hella cool)
+
+## How to use? 
+Exactly the same as docker, but, obviously, instead of `docker` write `podman`. More documentation find [there](https://podman.io/docs)
+
+Maybe (just maybe) you'll need to run this thing (but I still not ceratin if it's necessary):
+```sh
+systemctl --user enable --now podman.socket
+```

+# Used ports
+
+This file explains which ports are used and for what reason (please categorize them somehow and sort if possible)
+
+## Shared usage
+22 - ssh
+80 - caddy
+443 - caddy
+1024 - gitea exposed on that port inside the server (not allowed to use from outside)
+1025 - gitea exposed it's ssh on that port (therefore allowed from outside)
+
+## Rules
+If you want to add some extra port, then please:
+1. Check prs of other people
+2. Use 1024+ (because user for caddy isn't root and I don't want to change smth so please)
+
+There will be more, but that's all for now
