-# Building Mailpit from source
-
-Go (>= version 1.8) and npm are required to compile mailpit from source.
-
-```
-git clone git@github.com:axllent/mailpit.git
-cd mailpit
-```
-
-## Building the UI
-
-The Mailpit web user interface is built with node. In the project's root (top) directory run the following to install the required node modules:
-
-
-### Installing the node modules
-```
-npm install
-```
-
-
-### Building the web UI
-
-```
-npm run build
-```
-
-You can also run `npm run watch` which will watch for changes and rebuild the HTML/CSS/JS automatically when changes are detected.
-Please note that you must restart Mailpit (`go run .`) to run with the changes.
-
-
-## Build the mailpit binary
-
-One you have the assets compiled, you can build mailpit as follows:
-```
-go build -ldflags "-s -w"
-```
-
-## Building a stand-alone sendmail binary
-
-This step is unnecessary, however if you do not intend to either symlink `sendmail` to mailpit or configure your existing sendmail to route mail to mailpit, you can optionally build a stand-alone sendmail binary.
-
-```
-cd sendmail
-go build -ldflags "-s -w"
