 ## How to use
 
-1. Upload httpserver.lua using [luatool.py](https://github.com/4refr0nt/luatool) or equivalent.
+1. Upload server files using [luatool.py](https://github.com/4refr0nt/luatool) or equivalent.
+   Or, even better, use GNU Make with the bundled makefile. Type the following to upload
+   server, init, and some example files.
+
+         make upload
+
    Add the following to your init.lua in order to start the server:
 
          require("httpserver")
          server = httpserver.start(80, 10)
 
-   80 is the port your server is listening to, and 10 is the timeout (in seconds) for clients.
+   In this example, 80 is the port your server is listening to, and 10 is the timeout (in seconds) for clients.
 
-2. Upload the files you want to serve.
+2. Upload files you want to serve.
    Again, use luatool.py or similar and upload the HTML and other files.
 
    All the files you upload must be prefixed with "http/". Wait, what?
 
    Yes: NodeMCU's filesystem does not support folders, but filenames *can* contain slashes.
+   Only files that begin with "http/" will be accessible through the server.
 
 3. Visit your server from a web browser.
 
    __Example:__ Say the IP for your ESP8266 is 2.2.2.2 and the server is
    running in the default port 80. Go to http://2.2.2.2/index.html using your web browser. The ESP8266 will serve you with the contents
    of the file "http/myPage.html" (if it exists). If you visit the root (/)
-   then index.html is server. By the way, the URLs are case-sensitive.
+   then index.html is served. By the way, unlike some http servers, the URLs are case-sensitive.
 
 ## How to create dynamic Lua scripts

    For example, if the client requests _http://2.2.2.2/foo.lua?color=red_ then the server will execute the function
    in your Lua script _foo.lua_ and pass in _connection_ and _args_, where _args.color == "red"_.
 
+   The easiest is to look at some of the included example scripts.

 ## Not supported
 
 * Other methods: HEAD, POST, PUT, DELETE, TRACE, OPTIONS, CONNECT, PATCH
-* Server side scripting.
+* HTTP authentication
+* Encryption
 
 ## Open issues
+
 * File system doesn't like long names, need to protect:
 
         PANIC: unprotected error in call to Lua API (httpserver.lua:78: filename too long)
 
-* System is very, very memory constrained. Remote execution of Lua scripts only works with trivial scripts.
+* nodemcu firmware with floating point doesn't have enough memory to compile nor run the server. See below.
+
+* Binary files haven't been tested yet since luatool.py doesn't support uploading anything but text files.
+  If anyone has any luck with this, let us know!
+
+## A note on memory usage.
+
+   The chip is very, very memory constrained. If you find yourself having trouble running the server or anything beyond the most trivial scripts,
+   then try some of the following:
+
+   * Use a recent build of nodemcu-firmware that supports node.compile().
+     Compiled Lua code has extension .lc and has smaller memory footprint.
+     After uploading the server code (httpserver.lua) but before running anything,
+     type:
+
+         node.compile("httpserver.lua")
+
+   * If you can't even compile the server code, then you may need a build of the firmware without
+     floating point. In file nodemcu-firmware/app/lua/luaconf.h right around line 572 (line number
+     may change in the future) add
+
+         #define LUA_NUMBER_INTEGRAL
+
+     Then rebuild and re-flash the firmware. But if you **must** have floating point numbers and
+     run this server code, you may be out of luck.
+
+   * Any help reducing the memory needs of the server without crippling its features are appreciated!
