by all means...
You start by building a good kitchen or cooking place. Then:
1. Decide on wood or gas.
2. Set up a sustainable fuel source system to avoid the Easter Island scenario.
3. Cultivate enough patches of land for long-term agriculture.
4. Research what is naturally available to grow and hunt in a sustainable way.
5. Add mushrooms, nuts, seeds, eggs, beans, vegetables, rice, potatoes and fruit to your diet.
6. Keep some live stock for meat and food garbage disposal (like chickens).
7. Kill less people, make them your friends and start your own tribe.
I assume you already have cooking gear.
