 ## Getting the code
 Just clone it from the GitHub repository. Make sure you pass --recurse-submodules to git clone so all required submodules are also cloned.
 
+```bash
 % git clone --recurse-submodules https://github.com/BatchDrake/suscan.git
+```
 
 ## Building and installing Suscan
 In order to build Suscan, you will need the development files for the following packages:
-
-```
-sigutils fftw3 sndfile SoapySDR libxml-2.0
-```
+* sigutils
+* fftw3
+* sndfile
+* SoapySDR
+* libxml-2.0
 
 If you are in a Debian-like operating system, you will also need `cmake` and `build-essential`. 
 
 After installing all dependencies, enter Suscan's source directory and compile by typing:
 
-```
+```bash
 % cd suscan
 % mkdir build
 % cd build

-### Suscan's STARCon 2018 tentative TO-DO List
----
-#### Must-do
-- Add 7-segment widget
-- Fix main screen layout
-- Prevent self-correcting blocks from drifting (add limits)
-- Update inspector tab with information from Costas/Gardner's blocks
-- Add button to reset internal states of self-correcting blocks
-- Add configuration tab for look & feel properties
-- Add option to change Costas loop arm gains
-- Change Start/Stop button color
-- Add option to save inspector configuration
-- Tweak throttle speed
-- Add button to freeze channel view
-- Add channel view context menu
-- Add measurements menu to inspector spectrum
-- Save channel list as XML
-- Fix spectrum glitches on poor noise floor level calculation
-- Save inspector configuration as a .c file
-
-#### Desirable
-- Add SoapySDR support
-- Allow real-time frequency selection
-- Add full-spectrum analysis
-- Add inspector log window?
-- Generalize inspector API
-- Fix freezing when opening some small channels
-- Add baseband channel recorder
