+# SOCKET HTTP SERVER
+
+Once you're done, you should be able to start the web server inside the homework directory using `python -u http_server.py` and then point your web browser at locations like:
+	* http://localhost:10000/sample.txt
+	* http://localhost:10000/a_web_page.html
+	* http://localhost:10000/images/sample_1.png
+
+and see the corresponding file located under homework/webroot. Take a moment to look into the homework/webroot and see these files. 
+
+Inside this repository you'll find the http_server.py file. I've added enough stub code for the missing functions to let the server run. And there are more tests for you to make pass!
+
+You do NOT need to execute the `make_time.py` Python file. When a web user visits `http://localhost:1000/make_time.py` you only need to _serve up_ the contents of that file. But if you'd like to take on a challenge, then you _can_ choose to execute the file and serve up the result of performming that execution.
+
+
+## Building the Response
+
+Your `response_path` function will need to accomplish the following tasks:
+
+  * It should take a URI as the sole argument
+  * It should map the pathname represented by the URI to a filesystem location.
+  * It should have a ‘home directory’, and look only in that location.
+  * If the URI is a directory, it should return a plain-text listing of the directory contents and the mimetype text/plain.
+  * If the URI is a file, it should return the contents of that file and its correct mimetype.
+  * If the URI does not map to a real location, it should raise an exception that the server can catch to return a 404 response.
+
+Because your server will be transmitting files as bytes, you might want to try searching for "reading a file as bytes in Python".
+
+To find the correct mimetype for a file, you might find the following code helpful:
+
+```
+>>> import mimetypes
+>>> mimetypes.guess_type('file.txt')[0]
+    'text/plain'
+>>> mimetypes.types_map['.txt']
+    'text/plain'
+```
+
+## Use Your Tests
+
+As you work your way through the steps outlined above, look at your tests. Write code that makes them pass.
