-A STATEMENT ON LEGACY SUPPORT
-
-In the terminal world there is much cruft that comes from old and unsup‐
-ported terminals that inherit incompatible modes and escape sequences
-which noone is able to know, except when he/she comes from that time and
-developed a graphical vt100 emulator at that time.
-
-One goal of st is to only support what is really needed. When you en‐
-counter a sequence which you really need, implement it. But while you
-are at it, do not add the other cruft you might encounter while sneek‐
-ing at other terminal emulators. History has bloated them and there is
-no real evidence that most of the sequences are used today.

-st - simple terminal
---------------------
-st is a simple terminal emulator for X which sucks less.
-
-
-Requirements
-------------
-In order to build st you need the Xlib header files.
-
-
-Installation
-------------
-Edit config.mk to match your local setup (st is installed into
-the /usr/local namespace by default).
-
-Afterwards enter the following command to build and install st (if
-necessary as root):
-
- make clean install
-
-
-Running st
-----------
-If you did not install st with make clean install, you must compile
-the st terminfo entry with the following command:
-
- tic -sx st.info
-
-See the man page for additional details.
-
-Credits
--------
-Based on Aurélien APTEL <aurelien dot aptel at gmail dot com> bt source code.

+# Luke's build of st - the simple (suckless) terminal
+
+The [suckless terminal (st)](https://st.suckless.org/) with some additional
+features that make it literally the best terminal emulator ever:
+
+## Unique features (using dmenu)
+
++ **follow urls** by pressing `alt-l`
++ **copy urls** in the same way with `alt-y`
++ **copy the output of commands** with `alt-o`
+
+## Bindings for
+
++ **scrollback** with `alt-↑/↓` or `alt-pageup/down` or `shift` while scrolling the
+ mouse.
++ OR **vim-bindings**: scroll up/down in history with `alt-k` and `alt-j`.
+ Faster with `alt-u`/`alt-d`.
++ **zoom/change font size**: same bindings as above, but holding down shift as
+ well. `alt-home` returns to default
++ **copy text** with `alt-c`, **paste** is `alt-v` or `shift-insert`
+
+## Pretty stuff
+
++ Compatibility with `Xresources` and `pywal` for dynamic colors.
++ Default [gruvbox](https://github.com/morhetz/gruvbox) colors otherwise.
++ Transparency/alpha, which is also adjustable from your `Xresources`.
++ Default font is system "mono" at 14pt, meaning the font will match your
+ system font.
+
+## Other st patches
+
++ Boxdraw
++ Ligatures
++ font2
++ updated to latest version 0.8.4
+
+## Installation for newbs
+
+You should have xlib header files and libharfbuzz build files installed.
+
+```
+git clone https://github.com/LukeSmithxyz/st
+cd st
+sudo make install
+```
+
+Obviously, `make` is required to build. `fontconfig` is required for the
+default build, since it asks `fontconfig` for your system monospace font. It
+might be obvious, but `libX11` and `libXft` are required as well. Chances are,
+you have all of this installed already.
+
+On OpenBSD, be sure to edit `config.mk` first and remove `-lrt` from the
+`$LIBS` before compiling.
+
+Be sure to have a composite manager (`xcompmgr`, `picom`, etc.) running if you
+want transparency.
+
+## How to configure dynamically with Xresources
+
+For many key variables, this build of `st` will look for X settings set in
+either `~/.Xdefaults` or `~/.Xresources`. You must run `xrdb` on one of these
+files to load the settings.
+
+For example, you can define your desired fonts, transparency or colors:
+
+```
+*.font: Liberation Mono:pixelsize=12:antialias=true:autohint=true;
+*.alpha: 0.9
+*.color0: #111
+...
+```
+
+The `alpha` value (for transparency) goes from `0` (transparent) to `1`
+(opaque). There is an example `Xdefaults` file in this respository.
+
+### Colors
+
+To be clear about the color settings:
+
+- This build will use gruvbox colors by default and as a fallback.
+- If there are Xresources colors defined, those will take priority.
+- But if `wal` has run in your session, its colors will take priority.
+
+Note that when you run `wal`, it will negate the transparency of existing windows, but new windows will continue with the previously defined transparency.
+
+## Notes on Emojis and Special Characters
+
+If st crashes when viewing emojis, install
+[libxft-bgra](https://aur.archlinux.org/packages/libxft-bgra/) from the AUR.
+
+Note that some special characters may appear truncated if too wide. You might
+want to manually set your prefered emoji/special character font to a lower size
+in the `config.h` file to avoid this. By default, JoyPixels is used at a
+smaller size than the usual text.
