This meant that it could be used as a fully-featured\nhomeserver.\n\n### The Dendron experiment mainly served to give us an excuse to learn Go and reveal that a strangler-pattern style rewrite like this isn't a clear win.  The additional hop of the dendron loadbalancer/proxy caused operational complexity (additional timeouts; logging; IP rewrites; FD limits; etc) whilst buying nothing that a normal LB couldn't do.  Also, the strangler-pattern didn't give us enough freedom to rapidly fix the problems of Synapse's DB schema and storage layer.\n\n### As of March 9th 2017, matrix.org's Synapse is no longer running behind Dendron (but instead using a normal haproxy), and meanwhile all our next-generation homeserver development effort is going into [Dendrite](https://github.com/matrix-org/dendrite) (aka \"Dendron done right\" ;D), which in turn is built on [gomatrixserverlib](https://github.com/matrix-org/gomatrixserverlib), [matrix.org/util](https://github.com/matrix-org/util), and other libs.\n\n### As such, Dendron development is dead, succeeded by Dendrite.\n\nBuilding\n--------\n\nCurrently to use Dendron you will need an development install of Synapse. See\n[these instructions](https://github.com/matrix-org/synapse#synapse-development \"Synapse Development\") \nfor setting up a dev install of Synapse.\n\nTo build Dendron itself check out this repository and build it using [gb](https://getgb.io):\n\n    gb generate\n    gb build\n\n\nConfiguring\n-----------\n\nWARNING: Dendron is currently in the early stages of development. These\ninstructions are likely to change frequently and no effort is made to provide\nbackwards compatibility.\n\n### Configuring Synapse\n\nYou will need to configure Synapse to use [PostgreSQL](https://github.com/matrix-org/synapse#using-postgresql)\nfor storage.\n\nYou will need to setup an unsecure HTTP listener for Dendron to proxy requests to.\n\n### Configuring Dendron\n\nThe configuration for Dendron is passed on the command line.\n\n\nSyTest\n------\n\nDendron can be tested using [SyTest](https://github.com/matrix-org/sytest#dendron), a \nblack box matrix integration tester.
