In my start-up experience, building a great Team starts with you as an example. You as a start-up founder need to show them by example that you will do whatever it takes and work super hard to make your start-up success. Your team needs to see your dedication and passion for what you are building. Also, transparency is huge. Don't ever hide anything from your team, especially in an early stage. Your team needs to know how you are progressing every day, so sharing the progress dashboard with them is very important. Remember, together you are on a mission to change the world. Regarding the teaching your team members, it depends on what you are trying to convey. Maybe you can record an online video course where you teach your team members about the industry areas. What I found is that the best early employees are resourceful and they will try to figure out on their own. Let them know that you will be here to answer any question but also let them have their own steep learning curve. Encourage them to learn on their own. Hope this helps a bit

Giving out Equity of your company is tricky. Equity should not be given freely and not to everybody in your company. If you are giving an Equity, then vesting is the key, with a cliff of at least 1 year. I would avoid giving equity to people that you don't know, especially, to developers whom you will yet get to know. Partner and give Equity only to your trusted friends, and colleagues, whom you really know and trust. Hire developers/contractors. Use Upwork as a great resource. You can find a great talent there. If you don't have money to hire a freelancer (developer), use your Entrepreneurial skills to create another revenue stream, or find a job, bootstrap the first simple beta version to see whether people want your app in the first place.
