+git clone --depth 1 --recurse-submodules -j8 https://github.com/helix-editor/helix
+cd helix

+This will install the `hx` binary to `$HOME/.cargo/bin`.

+# Notes

 - server-client architecture via gRPC, UI separate from core
 - multi cursor based editing and slicing
 - WASM based plugins (builtin LSP & fuzzy file finder)
-- piece table-based tree structure for changes

 Structure similar to codemirror:
 
-text (ropes)
+- text (ropes)
 - column utils, stuff like tab aware (row, col) -> char pos translation
 - word/grapheme/code point utils and iterators
-state
+- state
 - transactions
   - changes
   - annotations (time changed etc)

-codemirror uses offsets exclusively with Line being computed when necessary
-(with start/end extents)
-lines are temporarily cached in a lineCache
