-The idea behind these layers is to **bring the characters to the fingers, rather
-than moving the fingers to the keys**. This approach is what makes those 34-key
-keyboards so comfortable, and the goal here is to get a comparable experience
-with any other keyboard — including your laptop’s.
+This is how modern ergonomic keyboards work — e.g. [Planck][47], [Atreus][44],
+[Corne][42], [Ferris][34]… The goal here is to propose an approach that works
+with any keyboard, including your laptop’s.

-- all programming symbols are moved to the comfortable 3×10 zone
+- all programming symbols in the comfortable 3×10 zone
 - symmetrical modifiers on the home row
 - Vim-like navigation in all apps
 - easier left-hand shortcuts
 - works with any keyboard
 
 
-Suitable for *all* keyboards
+Using Arsenik
 --------------------------------------------------------------------------------
 
-… well, all keyboards that have at least 3×10 finger keys and 3 thumb keys. So
-yes, pretty much every computer keyboard out there.
+Unlike Miryoku which requires 6 thumb keys, Arsenik has been designed to work
+with standard ANSI/ISO/laptop keyboards, leveraging the spacebar and the two
+Alt/Cmd keys.
 
-Miryoku requires 6 thumb keys, which tends to limit its use to ergonomic
-keyboards. Selenium works with 3, which means it’s usable with any standard ANSI
-or ISO keyboard (spacebar + Alt/Cmd keys), even non-programmable ones thanks to
-[kanata](https://github.com/jtroo/kanata); and it also works with minimalist
-keyboards like the [Ferris](https://github.com/pierrechevalier83/ferris) (only 4
-thumb keys).
+[Non-programmable keyboards are supported through kanata.](kanata)
 
-Of course, Selenium can be implemented in programmable keyboards with QMK, ZMK,
+Programmable keyboards should be trivial to configure with QMK, ZMK,
 Kaleidoscope, etc.
 
 
 No numbers? No problem.

-If your keyboard has no number row, we got you covered! From <kbd>Prog</kbd>

+Related Projects
 --------------------------------------------------------------------------------
 
-The main idea is settled (3 home-row mods + 3 layer-taps), but Selenium is still
-a work in progress in an early stage. Expect refinements.
+### Inspiration
 
-- NumPad layer
-- macOS support (KMonad / Karabiner)
-- sample QMK / ZMK implementations for common keyboards
-- variants for specific keyboard layouts
+- [Miryoku][1] for the main idea of using modifiers on the homerow and layer
+shifters under the thumbs;
+- [Lafayette][2] and [Ergo-L][3] for the <kbd>Symbol</kbd> layer, which has been
+blatantly taken *as is*.
 
+### Alternatives
 
-Why the name?
---------------------------------------------------------------------------------
+- [Extend][4] for the <kbd>Navigation</kbd> layer
+- [Neo][5] for the <kbd>Navigation</kbd> and <kbd>Symbol</kbd> layers
+- [Pascal Getreuer][6] for the <kbd>Symbol</kbd> layer
+
+### Non-Goals
 
-I believe 34-key keyboards like the [Ferris](https://github.com/pierrechevalier83/ferris)
-are the end game of ergonomic keyboards, and 34 is selenium’s atomic number. All
-other keyboards I’ve tried feel like unstable isotopes of the Ferris experience.
+- being the most efficient 3×5 layout — [Miryoku][1] is probably the most
+advanced approach for that, at least on custom 36-key keyboards;
+- being the most intuitive 3×5 layout — [Neo][4]’s navigation-and-numpad layer
+would be an easier alternative, but a more Vim-like approach has been preferred;
+- fitting any OS layout — Arsenik works best if your OS layout has either no
+AltGr layer at all (e.g. QWERTY, Colemak, Workman…), or an optimized AltGr layer
+([Lafayette][2], [Ergo-L][3]…).
 
-[Other cultural biases](https://en.wikipedia.org/wiki/Evolution_(2001_film))
-might have been involved as well, though this remains to be proven. :-)

+- ANSI variants assume all symbols in your keyboard layout are in their
+QWERTY-ANSI positions: works fine with most US layouts but Dvorak users will get
+a slightly different <kbd>Prog</kbd> layer.
+- AltGr variants use your layout’s AltGr layer instead of the <kbd>Prog</kbd>
+layer: perfect for layouts that already have an optimized AltGr layer, such as
+[QWERTY-Lafayette][10] and [Ergo-L][11].
+- “Easy” variants don’t use any homerow-mods and leave the left thumb key
+modifier unchanged — but they still use a <kbd>Prog</kbd> layer and put the
+<kbd>Backspace</kbd> and <kbd>Return</kbd> keys under the thumbs. A good
+starting point if you’re new to dual keys.
+

+
+Note that kanata can also use the laptop’s trackpoint buttons (e.g. ThinkPad)
+as two additional thumb keys. :-)
