-3. So it appears to be working, how can we check?
-  - we can check the sessions table
-  - we can also render a dynamic welcome message on the home page based on who is logged in!
-
-  add the object req.session.user object to the view!
-
-  ```
-  app.get('/', function(req, res) {
-    res.render('home.html.ejs', { user: req.session.user})
-  })
-  ```
-
-  ```
-  <% if (user) {%>
-    <h3>Welcome <%= user.email %></h3>
-  <% } %>
-  ```
 
 ## Challenges: Part 4 logout
 
 **Goal:** Add a route to log a user out
 
-1. Add a delete route /logout to users.js
-2. Install method override
-3. Add a form/button on the home page that links to that delete route
-
-What is that delete route going to delete? The user? what?
-Answer: the session!
-
-```
-<div>
-  <form method="post" action="users/logout?_method=DELETE">
-    <button>logout</button>
-  </form>
-</div>
-```
-
-```
-users.delete('/logout', (req,res) => {
-  req.session.destroy(function(err) {
-    res.redirect('/')
-  })
-})
-```
+1. Add a delete route / logout to users.js
+2. Install `method-override`
+3. Add a form/button on the home page that links to that `delete` route
 
 
-## Challenges: Part 5 How do we restrict routes?
 
-**Goal:**
-
-1. create an image router an image view index.html.ejs that just
-
-We need to check and see if there is a session, if there is, great! next()
-if not throw an error.
-
-```
-images.use(function(req, res, next) {
-  console.log(req.session)
-  if (req.session.user) {
-    next()
-  } else {
-    res.status(301).json({succes: false, data: 'not logged in'})
-  }
-})```
