@@ -13,16 +13,105 @@ The goal of this project is to make a simple implementation of the core features
 
   - use C
   - use xlib
-  - configuration at compile time / with command line arguments
   - IPC via unix signals
-  - optional features like sound support that can be disabled at compile time
+  - optional features like sound support
 
 I'm undecided on whether I want to include any GUI whatsoever, as kmousetool already has one if you want one. I might use a minimal UI library to add a GUI, but I don't really want a GTK or QT dependency.
 
 
-### Planned Features
+### Features
 
-  [ ] Click mouse after mouse movement stops
-  [ ] Drag mouse if mouse movement starts shortly after stopping
-  [ ] Play a sound on mouse click
-  [x] Unix signals for toggle/enable/disable
+  - Click mouse after mouse movement stops
+  - Drag mouse if mouse movement starts shortly after stopping
+  - Play a sound on mouse click
+    - defaults to using aplay
+  - Unix signals for toggle/enable/disable
+    - SIGHUP = toggle
+    - SIGUSR1 = enable
+    - SIGUSR2 = disable
+  - Status file
+    - defaults to /tmp/rtmouse-status.txt
+
+
+#### Planned Features
+
+  - Command line arguments
+  - Better configuration of audio playback method (right now it is just go find the execl call and modify it)
+
+
+### Dependencies
+
+  - a C compiler (should work with gcc, clang, tcc, cproc, etc.)
+  - libc
+  - xlib
+  - aplay, if you want sound. you can also change the audio playback command in the code
+
+
+### Config
+
+For now, modify `config.h` before building. I'll add a way to use command line
+arguments later. The default `config.h` is replicated below:
+
+```c
+struct Dwell_Config config =
+{
+    // Minimum movement before a mouse motion activates the dwell timer
+    .min_movement_pixels = 10,
+
+    // rtmouse will wait this long after mouse movement ends before clicking.
+    // default 500ms. you may want to make it longer
+    .dwell_time = 500 / TIMER_INTERVAL_MS,
+
+    // rtmouse will drag-click if you move the mouse within this timeframe
+    // after a click occurs.
+    .drag_time = 500 / TIMER_INTERVAL_MS,
+
+    // dragging only happens when this is on
+    .drag_enabled = true,
+
+    // sound plays on click when this is on
+    .sound_enabled = true,
+
+    // status_file will be modified with enabled/disabled/terminated statuses
+    // when this is on
+    .write_status = true,
+    .status_file = "/tmp/rtmouse-status.txt"
+};
+```
+
+
+### Install
+
+```bash
+./build.sh
+sudo ./install.sh
+```
+This will put `rtmouse` at `/usr/local/bin` and `mouse
+
+
+### Usage
+
+Run `rtmouse` and it'll start up.
+
+You can use `killall -HUP rtmouse` to toggle enabled/disabled state, or `-USR1/-USR2` to specifically enable and disable it respectively.
+
+
+#### i3wm
+
+I use i3wm, so here's how I'm integrating rtmouse with that.
+
+I put this in my i3 config:
+
+```
+exec --no-startup-id rtmouse
+bindsym $mod+z exec --no-startup-id killall -HUP rtmouse && killall -USR1 i3status
+```
+
+and then also add this to my i3status config:
+
+```
+order += "read_file rtmouse"
+read_file rtmouse {
+    path = "/tmp/rtmouse-status.txt"
+}
+```
