In addition to the I2P download, you need to install Java if you do not have it
already installed. I2P requires Java Runtime Version 7 or higher.
(Oracle,
OpenJDK, or
IcedTea
Java Version 7 or 8 recommended,
except Raspberry Pi: OpenJDK 9 for ARM,
PowerPC: IBM Java SE 7 or 8)
Determine your installed Java version here
or type java -version at your command prompt.
Windows: Java 8 is recommended. Java 9 or higher may not work.

Pick your I2P Bundle
When you download the I2P software bundle, you get everything you need to connect and start participating in the I2P network and community. It even includes basic applications for every user, like e-mail, bittorrent, and a basic I2P Site for you to personalize and share.
After you've installed, a set up wizard will help you configure a few important things like how much bandwidth you would like to share while your router begins to make connections to the network. After the set up wizard is complete, you will be directed to the console home page where you can access the rest of the applications or configure, monitor, or troubleshoot your I2P connections.


The most reliable way to launch the installer is from a terminal like this:
java -jar i2pinstall_0.9.48.jar
. This will launch the GUI installer.
Depending on how your computer is set up, you may be able to start the
installer by double-clicking the "i2pinstall_0.9.48.jar" file or
right-clicking the file and selecting "Open with Java".
Unfortunately, this behaviour is difficult to predict.
Intalação via linha de comandos (sem interface gráfica):
I2P can also be installed in a terminal environment, which may be especially useful for servers, containers, or certain virtual machines. If you wish to use the installer without a GUI, you can use the commandjava -jar i2pinstall_0.9.48.jar -console
to follow
the install procedure in your terminal.

I2P is available in the official repositories for Ubuntu Bionic and later, and Debian Buster and Sid. However, Debian Buster and Ubuntu Bionic (LTS) distributions will have older I2P versions. If you are not running Debian Sid or the latest Ubuntu release, use our Debian repo or Launchpad PPA to ensure you're running the latest I2P version.


I2P is now available as a Docker package from the Docker Hub. You may retrieve the image by running the 'docker pull' command.
docker pull meeh/i2p.i2p

Alternativamente, você pode buscar a fonte do monotone
ou via Git pelo git.repo.i2p ou Github.
Execute (tar xjvf i2psource_0.9.48.tar.bz2 ; cd i2p-0.9.48 ; ant pkg)
ou então
rode o instalador GUI ou instalação headless como acima.
O código Android está no monotone e no Github. A construção do Android requer o código I2P. Veja a documentação no código Android para requerimentos de construção e instruções adicionais.
Atualizações de lançamentos anteriores:
O lançamento tem disponível tanto atualização automática como manual.

Se a versão do roteador I2P que roda no seu computador é 0.7.5 ou posterior, novos lançamentos são automaticamente detectados. Para atualizar basta clicar no botão 'Baixar atualização' que aparece no painel do seu roteador.
Since 0.9.23, some releases are signed by str4d, whose signing key has been in the router since 0.9.9. Routers older than 0.9.9 will fail to verify update files signed by str4d, and will need to be manually updated using the process below.

- Download the file to your I2P installation directory and rename as i2pupdate.zip. (alternately, you can get the source as above and run "ant updater", then copy the resulting i2pupdate.zip to your I2P installation directory). You do NOT need to unzip the file.
- Clique em "Reiniciar"
- Apanhe uma xícara de café e volte dentro de 11 minutos.
