 (It is still very much a work in progress so a lot of things may seem incomplete)<br>
 For now it is just a single file editor. I plan to add a multi-file support with file pickers and tabs soon.<br>
 
+## Installation
+
+Binary can be installed with the following command:
+
+```bash
+curl https://syedm.dev/crib | sh
+```
+
+It requires `libruby-3.2.so` or `libruby.so.3.4` to be installed in the system.<br>
+It also requires `libmagic` to be installed (most systems have it preinstalled).<br>
+Currently only for Linux.<br>
+*Tested with arch linux and ubuntu*<br>

 * [ ] **Critical Crash:** Fix bug where closing immediately while LSP is still loading hangs and then segfaults (especially on slow ones like fish-lsp where quick edits and exit can hang).
 * [ ] **Line move:** fix the move line functions to work without the calculations from folds as folds are removed.
 * [ ] **Editor Indentation Fix:** - Main : merger indentation with the parser for more accurate results.
+    * [ ] Fix bug where enter at start of line with ending type crashes
     * [ ] Keep cache of language maps in engine to reduce lookup time.
     * [ ] In indents add function to support tab which indents if before any content and inserts a pure \t otherwise.
     * [ ] And backspace which undents if before any content.
