 This repository is a valid QMK external userspace as documented [here](https://docs.qmk.fm/newbs_external_userspace). To use it, you need:
 
-1. QMK setup locally. See [QMK Docs](https://docs.qmk.fm/newbs_getting_started) for details
-2. Clone this repository and add it as an overlay:
-
-   ```
-    qmk config user.overlay_dir="/home/chzerv/qmk_keymap/"
-   ```
-
-3. To build the firmware:
+1. QMK setup locally. See [QMK Docs](https://docs.qmk.fm/newbs_getting_started) for details.
    ```shell
+   qmk setup
+   ```
+2. Clone this repository locally.
+   ```
+    git clone https://github.com/chzerv/qmk_keymap
+   ```
+3. Add the cloned repository as an overlay (replace `path/to/qmk_keymap` with the path of the cloned repo).
+
+   ```shell
+
+   qmk config user.overlay_dir="$(realpath path/to/qmk_keymap)"
+   ```
+
+4. (optional) set a default keyboard and keymap.
+
+   ```shell
+   qmk config user.keyboard=keebio/iris_ce/rev1
+   qmk config user.keymap=chzerv
+   ```
+
+5. Build and flash.
+
+   ```shell
+   qmk compile -kb keebio/iris_ce/rev1 -km chzerv
    qmk flash -kb keebio/iris_ce/rev1 -km chzerv
+
+   # Or, if you followed step #4
+   qmk compile
+   qmk flash
    ```
 
 ## TODO
 
 - [ ] My symbol layer needs a bit more tweaking
-- [x] Make my `Control/Escape` mod-tap send a one-shot `Ctrl` when held
+- ~~Make my `Control/Escape` mod-tap send a one-shot `Ctrl` when held~~
+  - Turns out this causes more trouble than it solves:
+    - `Ctrl + Mouse` doesn't work
+    - `Ctrl` only applies to the first key, which makes shortcuts like deleting backwards in the shell using `Ctrl+h` feel very awkward, as you have to keep pressing `Ctrl`
