Many applications are available that interface with I2P, including mail, peer-peer, IRC chat, and others.
Install thepackage for the daemon written in C++ which may suit hardware with limited resources or AUR for the development version.
The I2P homepage also provides a pre-compiled binary which includes command line (headless) option and can be installed in the user's home directory. In this case I2P will auto update itself through the i2p network.
If you installed i2pd, you will have to start and optionally also enable the

Open your browser of choice and visit the I2P welcome page at
127.0.0.1:7070 for the daemon or
127.0.0.1:7657 for the suite (see the FAQ). From here you can navigate to I2Ps configuration and statistics pages, and links to Eepsites. Also, be aware that eepsites are unavailable until the daemon has bootstrapped to the network, which can take several minutes.
In order to visit eepsites configure your browser to use the local proxy:
