-At long last... something useful
-================================
-
-It's been 2 years of me mostly not having time to work on go-i2p itself since my last update.
-However, after much waiting, this library is actually **useful** for something.
-It is now being used in the `reseed-tools` application to examine RouterInfos prior to including them in reseed bundles.
-Routers that self-report as unreachable or congested will be excluded from future reseed bundles.
-Additionally, routers that self-report an old version will be excluded from reseed bundles.
-This should help new users build better connections faster with the existing, working router implementations.
-
-This is not a working release of a go-i2p router
-------------------------------------------------
-
-It is a numbered version of the go-i2p library, which is pre-release, expressly for use in the `reseed-tools` application.
-The common library works, and so do some of the cryptographic primitives, however the API is unstable and the software itself is certain to have serious bugs outside of a few well-tested areas.
-If you're using it for something other than parsing and analyzing RouterInfos and LeaseSets, you'll probably encounter bugs.
-Please report them to the https://github.com/go-i2p/go-i2p
-Use any part of it at your own risk.

+## Verbosity ##
+Logging can be enabled and configured using the `DEBUG_I2P` environment variable. By default, logging is disabled.
+
+There are three available log levels:
+
+- Debug
+```shell
+export DEBUG_I2P=debug
+```
+- Warn
+```shell
+export DEBUG_I2P=warn
+```
+- Error
+```shell
+export DEBUG_I2P=error
+```
+
+If DEBUG_I2P is set to an unrecognized variable, it will fall back to "debug".
+
+## Fast-Fail mode ##
+
+Fast-Fail mode can be activated by setting `WARNFAIL_I2P` to any non-empty value. When set, every warning or error is Fatal.
+It is unsafe for production use, and intended only for debugging and testing purposes.
+
+```shell
+export WARNFAIL_I2P=true
+```
+
+If `WARNFAIL_I2P` is set and `DEBUG_I2P` is unset, `DEBUG_I2P` will be set to `debug`.

+
+**Test Coverage**: Core components have basic test coverage including NTCP2 sessions, I2NP message processing, and tunnel message parsing.

+### reseeding
+
+## Usage
+
+#### type Bootstrap
+
+```go
+type Bootstrap interface {
+	// get more peers for bootstrap
+	// try obtaining at most n router infos
+	// if n is 0 then try obtaining as many router infos as possible
+	// returns nil and error if we cannot fetch ANY router infos
+	// returns a channel that yields 1 slice of router infos containing n or fewer router infos, caller must close channel after use
+	GetPeers(ctx context.Context, n int) ([]router_info.RouterInfo, error)
+}
+```
+
+interface defining a way to bootstrap into the i2p network
+
+#### type ReseedBootstrap
+
+```go
+type ReseedBootstrap struct {
+}
+```
+
+ReseedBootstrap implements the Bootstrap interface using HTTP reseeding
+
+#### func  NewReseedBootstrap
+
+```go
+func NewReseedBootstrap(config *config.BootstrapConfig) *ReseedBootstrap
+```
+NewReseedBootstrap creates a new reseeder with the provided configuration
+
+#### func (*ReseedBootstrap) GetPeers
+
+```go
+func (rb *ReseedBootstrap) GetPeers(ctx context.Context, n int) ([]router_info.RouterInfo, error)
+```
+GetPeers implements the Bootstrap interface by obtaining RouterInfos from
+configured reseed servers
