=== Deploy httpd to ESP8266 ===
  * Download ''httpd.c'' [[https://raw.githubusercontent.com/lichnak/nodemcu-labka/master/src/node_server_20170311/firmware/httpd.c|here.]]
  * Copy file ''httpd.c'' to folder ''app/modules/''
<code>
  cp httpd.c ~/nodemcu-firmware/nodemcu-firmware-2.0.0-master_20170202/app/modules/
</code>
  * Edit file ''app/include/user_modules.h'' and add one line to user modules.
<code>
mcedit ~/nodemcu-firmware/nodemcu-firmware-2.0.0-master_20170202/app/include/user_modules.h

#define LUA_USE_MODULES_HTTPD
</code>
  * Compile firmware as was descibed [[:project:nodemcu_lbe:en|here]] or download compiled bootloader [[https://github.com/lichnak/nodemcu-labka/raw/master/src/node_server_20170311/firmware/0x00000.bin|here]] and firmware [[https://github.com/lichnak/nodemcu-labka/raw/master/src/node_server_20170311/firmware/0x10000.bin|here]]
  * Connect nodeMCU to USB
{{ project:wiki_nodemcu_lolin.png }}
  * Upload bootloader //bin/0x00000.bin// and firmware //bin/0x10000.bin// to ESP8266 as was descibed for Windows 10 [[:project:nodemcu_windev:en|here]] and for Ubuntu [[:project:nodemcu_ubudev:en|here]]
