+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.

-# st - simple terminal
-
-st is a simple terminal emulator for X which sucks less.
-
-## Notes about this fork
-
-This is a fork of st, the original repo can be found here: [https://git.suckless.org/st/](https://git.suckless.org/st/)
-
-The original st webpage is here: [https://st.suckless.org/](https://st.suckless.org/)
-
-### Available patches
-
-* [Alpha](https://st.suckless.org/patches/alpha/) : This patch allows users to change the opacity of the background. Note that you need an X composite manager (e.g. compton, xcompmgr) to make this patch effective.
-* [Clipboard](https://st.suckless.org/patches/clipboard/) : This trivial patch sets CLIPBOARD on selection.
-* [font2](https://st.suckless.org/patches/font2/) : This patch allows to add spare font besides default.
-* [Wide glyph](https://st.suckless.org/patches/glyph_wide_support/) : This patch allows to display the full glyph instead of it being cut off. See also [here](https://github.com/LukeSmithxyz/st/pull/349)
-
-#### Colorscheme patch
-The colorscheme patch is a custom patch, it is not the ones from [colorscheme](https://st.suckless.org/patches/colorschemes/)
-It is `solarized.dark` exported from https://terminal.sexy with a different bg and fg color.
-Also the `defaultfg`, `defaultbg` and `defaultcs` are not `static`s, otherwise it won't compile.
-
-### Previous available patches
-
-* [Fix Keyboard Input](https://st.suckless.org/patches/fix_keyboard_input/) : Add a few previously undefined keys.
-Removed as this was used for additional keys for zooming.
-
-### Applying/Removing Patches
-Applying patches from this repository use:
-
-- applied all at once without committing:
-```
-git apply patches/*
-```
-
-- applied as individual commits
-```
-git am patches/*
-```
-
-Applying patches from https://st.suckless.org/patches/ use:
-```
-# Add custom patch
-patch -Np1 -i patches/custom.diff
-or
-patch < patch.diff
-
-# Remove st-alpha-201806-16-0.81 patch
-patch -R patches/st-alpha-20180616-0.8.1.diff
-```
-
-## 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):
-
-```bash
-make clean install
-```
-
-## Running st
-
-Start `st` from a launcher like dmenu or rofi.
-
-If you did not install st with make clean install, you must compile
-the st terminfo entry with the following command:
-
-```bash
-tic -sx st.info
-```
-
-See the man page for additional details.
