+## On Connecting to Your Wireless Network From the ISO The first time
+
+The handbook doesn't cover exactly how to connect wirelessly the first time. It
+can't solely be done via dhcpcd.
+
+Firstly find your wireless card interface reference:
+
+```sh
+ip addr
+```
+
+Or:
+
+```sh
+ifconfig
+```
+
+It will look like `wlps60` or something like that.
+
+The ISO comes with wpa_supplicant for connecting. First configure wpa_supplicant
+with your WIFI SSID and password:
+
+```sh
+wpa_passphrase "SSID" "PASSWORD" > /etc/wpa_supplicant/wpa_supplicant.conf
+```
+
+Then configure wpa_supplicant to recognize this wifi network:
+
+```sh
+wpa_supplicant -B -i wlps60 -c /etc/wpa_supplicant/wpa_supplicant.conf
+```
+
+Then use `dhcpcd` to grab an IP address:
+
+```sh
+dhcpcd wlps60
+```
+
+And use `ping` to test:
+
+```sh
+ping 8.8.8.8
+```
+
+You might still have trouble downloading the stage 3 tarball if your DNS does
+not resolve. In which case simply edit `/etc/resolv.conf` directly:
+
+```
+# /etc/resolv.conf
+# Quad 9
+nameserver 9.9.9.9
+nameserver 149.112.112.112
+
+# Alternatively:
+# Cloudflare
+nameserver 1.1.1.1
+nameserver 1.0.0.1
+```
+
+## General Notes
+
+A general speedrun guide to installing gentoo can be found at:
+
+https://www.reddit.com/r/Gentoo/comments/td684v/need_help_for_first_time_setting_up_a_virtual/
+
+Install a basic distribution-bin kernel first, then you can:
+
+You can get your current compiler flags from:
+
+zcat /proc/config.gz
+
+You can just output it and then save it as a default that you have.
+
+Also, you can find these same compiler flags in:
+
+/usr/lib/modules/$(uname -r)/build/.config
+
+You actually can use this in the /usr/src/linux-kernel-version
+
+But you just want to make sure to run: `make olddefconfig` to update with new
+options/safe defaults before running the compiling make commands documented in
+the Gentoo Handbook.
+
+Watch mental outlaws videos on configuring the kernel (one is more in depth than
+the others). Make notes on the options he changes and actually research the
+specific flags he configures in the handbook.
+
+At some point you can adjust the number of threads the kernel can use, which
+apparently defaults to a high number. Your Ryzen has 24 threads, but you can
+find out specifically by running
+
+```
+grep -c processor /proc/cpuinfo
+```
+
+Or:
+
+```
+lscpu
+```
+
+And looking at the "Thread(s) per core" section.
