+### 1. What is bootstrap.dat?
+
+It is a flat, binary file containing bitcoin blockchain data starting from the
+genesis block and continuing through a relatively recent block height depending
+on the last time it was updated.
+
+See [this](https://bitcointalk.org/index.php?topic=145386.0) thread on
+bitcointalk for more details.
+
+**NOTE:** Using bootstrap.dat is entirely optional.  Btcd will download the
+block chain from other peers through the Bitcoin protocol with no extra
+configuration needed.
+
+<a name="ProsCons" />
+### 2. What are the pros and cons of using bootstrap.dat?
+
+Pros:
+- Typically accelerates the initial process of bringing up a new node as it
+  downloads from public P2P nodes and generally is able to achieve faster
+  download speeds
+- It is particularly beneficial when bringing up multiple nodes as you only need
+  to download the data once
+
+Cons:
+- Requires you to setup and configure a torrent client if you don't already have
+  one available
+- Requires roughly twice as much disk space since you'll need the flat file as
+  well as the imported database
+
+<a name="Obtaining" />
+### 3. Where do I get bootstrap.dat?
+
+The bootstrap.dat file is made available via a torrent.  See
+[this](https://bitcointalk.org/index.php?topic=145386.0) thread on bitcointalk
+for the torrent download details.
+
+<a name="Trust" />
+### 4. How do I know I can trust the bootstrap.dat I downloaded?
+
+You don't need to trust the file as the `addblock` utility verifies every block
+using the same rules that are used when downloading the block chain normally
+through the Bitcoin protocol.  Additionally, the chain rules contain hard-coded
+checkpoints for the known-good block chain at periodic intervals.  This ensures
+that not only is it a valid chain, but it is the same chain that everyone else
+is using.
+
+<a name="Importing" />
+### 5. How do I use bootstrap.dat with btcd?
+
+btcd comes with a separate utility named `addblock` which can be used to import
+`bootstrap.dat`.  This approach is used since the import is a one-time operation
+and we prefer to keep the daemon itself as lightweight as possible.
+
+1. Stop btcd if it is already running.  This is required since addblock needs to
+   access the database used by btcd and it will be locked if btcd is using it.
+2. Note the path to the downloaded bootstrap.dat file.
+3. Run the addblock utility with the `-i` argument pointing to the location of
+   boostrap.dat:<br /><br />
+**Windows:**
+```bat
+C:\> "%PROGRAMFILES%\Btcd Suite\Btcd\addblock" -i C:\Path\To\bootstrap.dat
+```
+**Linux/Unix/BSD/POSIX:**
+```bash
+$ $GOPATH/bin/addblock -i /path/to/bootstrap.dat
+```
