 # piazzaoptical.com
 
-Code for what once was piazzaoptical.com. Backend and frontend.
+Code for what once was piazzaoptical.com. Backend and frontend. Unfortunately, I lost the code of the final product; this is the code of a very early stage, and errors abound.
 
 ## To use:
 
-```bash
-podman run -it --rm -p 8000:8000 docker.io/library/alpine:3.14  # v3.15 can't seem to work with package "bsd-compat-headers"
-```
-
-Then within the container:
+First clone this repo, and the `bitser` repo that's included as a submodule:
 
 ```bash
-apk add --no-cache build-base bsd-compat-headers m4 openssl-dev libmagic libuuid lmdb lmdb-dev git readline-dev autoconf automake libtool zlib-dev vips ncurses wget unzip openssl util-linux-dev bash
-ln -s /usr/lib/libvips.so.42 /usr/lib/libvips.so
-git config --global url."https://".insteadOf git:// # for luarocks pulling from github; it uses unencrypted
-git clone https://git.sakal.us/brian/luaver.git ~/.luaver
-bash
+git clone https://git.sakal.us/brian/piazzaoptical.com
+cd piazzaoptical.com
+git submodule update --init --recursive  # for bitser; installed as git submodule
 ```
 
-Then in `bash` shell (not the default `ash`):
+Build the podman image based on the Containerfile:
 
 ```bash
-. ~/.luaver/luaver
-yes | luaver install 5.1.5
-yes | luaver install-luajit 2.0.5
-luaver use 5.1.5
-luaver use-luajit 2.0.5
-yes | luaver install-luarocks 3.8.0
-luaver use-luarocks 3.8.0
-luarocks install luarocks-fetch-gitrec # for magic
-luarocks install compat53
-luarocks install cqueues 
-luarocks install lpeg 
-luarocks install lpeg_patterns 
-luarocks install luafilesystem 
-luarocks install http 
-luarocks install lua-cjson 
-luarocks install mimetypes 
-luarocks install lrandom 
-luarocks install luaprompt
-luarocks install magic 
-luarocks install lightningmdb 
-luarocks install lua_uuid
-luarocks install lua-vips
+podman build --tag piazzaoptical.com .
 ```
 
-Finally:
+Finally, run a container based on this image (I chose to expose the container through port 8004 on the host):
 
 ```bash
-git clone https://git.sakal.us/brian/piazzaoptical.com
-cd piazzaoptical.com
-git submodule update --init --recursive  # for bitser; installed as git submodule
-cd server
-luajit ./server.lua
+podman run -it --rm -p 8004:8000 -v ${PWD}:/app localhost/piazzaoptical.com
