How-To: Claim neurons for seed participants
You are a seed participant if you donated to the DFINITY foundation in February of 2017. At that time, 30 tokens per Swiss Franc of value donated were allotted to your key. These tokens are now called "ICP tokens" or, shortly, "ICP".
At Genesis Unlock your ICP were then disbursed to you in the form of a basket of 49 voting neurons (insert link "NNS" here). These neurons already exist inside the Network Nervous System (insert link "NNS" here). Your neurons contain the ICP you have been awarded, staked inside.
Your neurons have been configured to vote automatically and are already earning voting rewards for you. You do not need to do anything to initialize your neurons in order to continue earning voting rewards.
The 49 neurons created for you have dissolve delays (insert link "NNS" here) of 0 days, 30 days, 60 days, 90 days and so on. Apart from the first neuron which has a dissolve delay of 0 days (which can be dissolved immediately), the other dissolve delays may have a small random number of days either added or removed.
We are pleased to inform you that your neurons have been pre-aged! At the moment of Genesis Unlock, their age was already set to 18 months old. This is important, because neuron age significantly increases your voting power and the voting rewards you receive.
To control your neurons you must use the same secret key that you generated when the donation was made. It was recorded as a 12-word mnemonic phrase. In order to control your neurons you need to first claim the whole basket. This article explains how to do the claiming. For how to control your neurons after claiming them see this article (insert link here).
Claiming with a Ledger Nano device
Coming soon. This will come with the next update of the IC's app for the Ledger Nano. The current release can manage neurons but cannot yet claim them.
Claiming with an air-gapped computer
Since you need to make use of your secret it is highly advised that you use an air-gapped computer for the purpose of claiming. If you are not comfortable with such a setup or with any of the following steps then you have to wait for the next release of the IC's app for the Ledger Nano device.
As an air-gapped device you can use a Windows, Linux (x86 or arm) or MacOS machine.

You need two tools. They are called keysmith and quill.
