-# 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"

 - SMTP server (default `0.0.0.0:1025`)
 - Web UI to view emails (HTML format, text, source and MIME attachments, default `0.0.0.0:8025`)
 - Real-time web UI updates using web sockets for new mail
-- Optional basic authentication for web UI (see [wiki](https://github.com/axllent/mailpit/wiki/Basic-authentication))
-- Email storage in either memory or disk (using [CloverDB](https://github.com/ostafen/clover)) - note that in-memory has a physical limit of 1MB per email
 - Configurable automatic email pruning (default keeps the most recent 500 emails)
+- Email storage either in memory or disk ([see wiki](https://github.com/axllent/mailpit/wiki/Email-storage))
 - Fast SMTP processing & storing - approximately 300-600 emails per second depending on CPU, network speed & email size
 - Can handle tens of thousands of emails

 ## Installation
 
 Download a pre-built binary in the [releases](https://github.com/axllent/mailpit/releases/latest). The `mailpit` can be placed in your `$PATH`, or simply run as `./mailpit`. See `mailpit -h` for options.
