1.) Sign up with a pool. i.e. give-me-coins.com
2.) Set a password for the worker on the website

3.) Use bfgminer rather than cminer. CPU mining is supported, but GPU mining would be better.

Starting BFGminer:

export GPU_MAX_ALLOC_PERCENT=100
export DISPLAY=:0
#shows all GPUs
./bfgminer -n

Paste the following into your console
You will need to find out the best –thread-concurrency for your card and put it in the command line
for
7950s 16384 seems to work well and for
6950 and 58XX cards 8000 is a good starting point
so for a 7950 you would put

./bfgminer --scrypt --opencl:auto -o http://ltc.give-me-coins.com:3334 -u "your worker name" -p "your worker password" --thread-concurrency 16384 -w 256 --gpu-engine 1125 --gpu-memclock 1250 --auto-fan --auto-gpu -g 1 -I 18

For CPU-Mining something like this would work, but it is VEEEERY slow (about 28Kh/s):

#!/bin/sh
export GPU_MAX_ALLOC_PERCENT=100
export DISPLAY=:0
./bfgminer --scrypt --cpu-threads 3 -o http://ltc.give-me-coins.com:3334 -u "test98765.1" -p "hChP8B9kb" --thread-concurrency 16384 -w 256 --gpu-engine 1125 --gpu-memclock 1250 --auto-fan --auto-gpu -g 1 -I 18

cd /usr/src
wget https://download.litecoin.org/litecoin-0.14.2/linux/litecoin-0.14.2-x86_64-linux-gnu.tar.gz
tar -xvzf litecoin-0.14.2-x86_64-linux-gnu.tar.gz 
cd litecoin-0.14.2/
cd bin
./litecoin-qt

will download about 8GB data. After download, the following can be used to prune the data to about 2GB:

./litecoin-qt --prune=1000
