+# st
+
+This is my patched version of st. The base version is directly from suckless.org.
+This belongs to my larbs installation script, but does not directly depend on it.
+It is supposed to work in the environment after the larbs-base-installation.
+
+## Patches
+
+The list below shows the currently applied patches to the master branch.
+
+- st-alpha-20220206-0.8.5.diff (adds transparency)
+- st-anysize-20220718-baa9357.diff (st leaves no gaps if the height/width doesn't match a multiple of
+  character height)
+- st-externalpipe-0.8.4.diff (allows reading and writing st's screen through a pipe)
+- st-ligatures-scrollback-20230105-0.9.diff (scrollback compatible addition of ligatures)
+- st-scrollback-0.8.5.diff (add scrollback functionality)
+
+## Hotkeys
+
+There are various shortcuts and hotkeys used in this version. Included in my build are the following.
+
+| ModKey | Shift | Key             | Function                                     |

+| Alt    |       | o               | copy output of previous command to clipboard |
+
+## Installation
+
+The most basic way is to clone the repository and then invoke make.
+
+- `git clone https://github.com/tiyn/st`
+- `make clean install`
