BEFORE YOU BEGIN
You should install the modified bootloader that allows you to get into fastboot mode if necessary. This is because there is only one kernel on the A1, and if the kernel causes problems (unlikely, but it's better save yourself the risk) you won't be able to boot normally or into recovery. Being able to boot into fastboot mode gives you a way out of this by allowing you to flash a kernel through usb with the fastboot command.

Simple installation guide
David Artiss has written a beginners' guide that walks you through the process of installing CM7 starting from the stock system. Get to it here:
Syncing and building it:
Clone the Cyanogenmod repository:
repo init -u git://github.com/CyanogenMod/android.git -b gingerbread
git clone https://github.com/milaq/android.git local-android cd local-android git checkout gingerbread cd .. cp local-android/local_manifest.xml android/.repo
cd android repo sync ./vendor/cyanogen/get-rommanager source build/envsetup.sh && brunch A1_07
Graphics HW acceleration
Buttons (vol, power, menu, back, home)
Removable SD card
Wifi (see caveat below)
Internal SD card
Front and back camera for still images, video recording from back camera
HW accelerated decoding (h.264 etc)
No 3G on the 3G versions.
Video recording from the front camera
Accelerometer switch not working
Market gives phone layout instead of tablet layout after update
Modified partition layout used with CWM 184.108.40.206 seems to prevent the internal SD card mounting.
GPS Time from android.location.Location.getTime() is wrong (1 day ahead?).
DSPManager sometimes crashes when headphones are inserted.
Bluetooth file transfer doesn't work, but Bluetooth HID seems to work.
