Making the Neti Pot solution, which is really just saline/salt water couldn't be much easier.
Put a cup or two of sterilized water into a pot and warm it up on the stove. You can start with distilled water from the store, or purified water from a test reliable source.
Once the water is warm, pour it into the Netti Pot and then grab your salt. Take about half a teaspoon of salt and put it into your water mixture. Stir it well.
Now you are ready to proceed. Find a sink, some privacy and read on.
