+### Pull Request Process
+
+After you are done implementing the feature or fixing a bug, make sure your forked repository 
+is up to date with the original repository. To complete this step, execute the following commands:
+
+```sh
+git remote add upstream [email protected]:FreezingMoon/AncientBeast.git
+git checkout master
+git pull upstream master
+```
+
+After you have pulled all the changes from the original remote repository, push your changes 
+to your forked repository. Do NOT attempt to push to the original repository. 
+To complete this step, execute the following commands:
+
+```sh
+git rebase master
+git push --set-upstream origin master
+```
+
+The changes are now in your forked GitHub repository, and you are ready to open a pull request. If the purpose 
+of your commit was to implement a fix for one of the currently open issues, please reference the name of 
+the issue in the name of the pull request. Write a descriptive message for the changes you have implemented. 
+
+*Please provide your EC20 wallet address*, especially if you are addressing an issue with a bounty.
+
+Warning: make sure that you are providing a *wallet* address and not a deposit address to an exchange.
