+### Install engine from source to Mycroft
+
+Pre-requirests: Working **Source Install**, Mycroft source install and http server.
+
+After messing with the source code you can build a `precise-engine` and `precise-runner`
+executables and install them to your Mycroft Source installation.
+
+```bash
+source .venv/bin/activate # Gain access to precise-* executables
+
+./bash build.sh  #Build a new executables
+
+rm -r /home/user/.mycroft/precise/precise-engin*  #Remove old precise engine
+cp -r ./mycroft-precise/dist/precise-engin* /var/www/html/ #Copy a new build tarball with md5 hash to your http server
+
+mycroft-pip install ./mycroft-precise/runner  #Install a new build precise runner to Mycroft
+
+mycroft-config edit user   #Add information about a new precise module to Mycroft user config

+
+At first run, Mycroft  will try to download the new engine and install it. Mycroft will show INFO 
+messages about it in CLI. After succesful installation, You can start to use it.  
+  
+If anything goes wrong, Mycroft will prompt You with error messages in CLI.  
+  
+To revert installed engine remove directory `precise-engine` and `precise-engine*.tz.gz` from
+ `/home/user/.mycroft/precision/` directory, remove config entry added in steps above and restart
+ Mycroft. It will automatically download and install stable release.

 ## How it Works
 
 At it's core, Precise uses just a single recurrent network, specifically a GRU.
