+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"

+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only

-# Это заготовка для нормального файла
+# Chrly

-Для настройки Dev-окружения нужно склонировать проект в удобное место,
-за тем сделать символьную ссылку в свой GOPATH:
+Chrly is a lightweight implementation of Minecraft skins system server. It's packaged and distributed as a Docker
+image and can be downloaded from [Dockerhub](https://hub.docker.com/r/elyby/chrly/). App is written in Go, can
+withstand heavy loads and is production ready.

-```sh
-# Выполнять, находясь внутри директории репозитория
-mkdir -p $GOPATH/src/elyby
-ln -s $PWD $GOPATH/src/elyby/minecraft-skinsystem
+## Installation
+
+You can easily install Chrly using [docker-compose](https://docs.docker.com/compose/). The configuration below (save
+it as `docker-compose.yml`) can be used to start a Chrly server. It relies on `CHRLY_SECRET` environment variable
+that you must set before running `docker-compose up -d`. Other possible variables are described below.
+
+```yml
+version: '2'
+services:
+  app:
+    image: elyby/chrly
+    hostname: chrly0
+    restart: always
+    links:
+      - redis
+    volumes:
+      - ./data/capes:/data/capes
+    ports:
+      - "80:80"
+    environment:
+      CHRLY_SECRET: replace_this_value_in_production
+
+  redis:
+    image: redis:4.0-32bit
+    restart: always
+    volumes:
+      - ./data/redis:/data
 ```

-Или можно склонировать репозиторий сразу в нужную локацию:
+Chrly will mount some volumes on the host machine to persist storage for capes and Redis database.
+
+### Config
+
+Application's configuration is based on the environment variables. You can adjust config by modifying `environment` key
+inside your `docker-compose.yml` file. After value will have been changed, container should be stopped and recreated.
+If environment variables have been changed, Docker will automatically recreate the container, so you only need to `stop`
+and `up` it:

 ```sh
-git clone git@bitbucket.org:elyby/minecraft-skinsystem.git $GOPATH/src/elyby/minecraft-skinsystem
+docker-compose stop app
+docker-compose up -d app
 ```

-Нужно скопировать правильный docker-compose файл для желаемого окружения:
+**Variables to adjust:**

-```sh
-cp docker-compose.dev.yml docker-compose.yml  # dev env
-cp docker-compose.prod.yml docker-compose.yml # prod env
+| ENV                | Description                                                                        | Example                                   |
+|--------------------|------------------------------------------------------------------------------------|-------------------------------------------|
+| STORAGE_REDIS_POOL | By default, Chrly creates pool with 10 connection, but you may want to increase it | `20`                                      |
+| STATSD_ADDR        | StatsD can be used to collect metrics                                              | `localhost:8125`                          |
+| SENTRY_DSN         | Sentry can be used to collect app errors                                           | `https://public:private@your.sentry.io/1` |
+
+If something goes wrong, you can always access logs by executing `docker-compose logs -f app`.
+
+## Endpoints
+
+Each endpoint that accepts `username` as a part of an url takes it case insensitive. `.png` part can be omitted too.
+
+#### `GET /skins/{username}.png`
+
+This endpoint responds to requested `username` with a skin texture. If user's skin was set as texture's link, then it'll
+respond with the `301` redirect to that url. If there is no record for requested username, it'll redirect to the
+Mojang skins system as: `http://skins.minecraft.net/MinecraftSkins/{username}.png` with the original username's case.
+
+#### `GET /cloaks/{username}.png`
+
+It responds to requested `username` with a cape texture. If user's cape file doesn't exists, then it'll redirect to the
+Mojang skins system as: `http://skins.minecraft.net/MinecraftCloaks/{username}.png` with the original username's case.
+
+#### `GET /textures/{username}`
+
+This endpoint forms response payloads as if it was the `textures`' property, but without base64 encoding. For example:
+
+```json
+{
+    "SKIN": {
+        "url": "http://ely.by/minecraft/skins/skin.png",
+        "hash": "55d2a8848764f5ff04012cdb093458bd",
+        "metadata": {
+            "model": "slim"
+        }
+    },
+    "CAPE": {
+        "url": "http://skinsystem.ely.by/cloaks/username",
+        "hash": "424ff79dce9940af89c28ad80de8aaad"
+    }
+}
 ```

-И за тем всё это поднять:
+If record for the requested username wasn't found, cape would be omitted and skin would be formed for Mojang skins
+system. Hash would be formed as the username plus the half-hour-ranged time of request, which is needed to improve
+caching of Mojang skins inside Minecraft.
+
+That request is handy in case when your server implements authentication for a game server (e.g. join/hasJoined
+operation) and you have to respond with hasJoined request with an actual user textures. You have to simply send request
+to the Chrly server and put the result in your hasJoined response.
+
+#### `GET /textures/signed/{username}`
+
+Actually, it's [Ely.by](http://ely.by) feature called [Server Skins System](http://ely.by/server-skins-system), but if
+you have your own source of the Mojang signatures, then you can pass it with textures and it'll be displayed in this
+method. Received response should be directly sent to the client without any modification via game server API.
+
+Response example:
+
+```json
+{
+    "id": "0f657aa8bfbe415db7005750090d3af3",
+    "name": "username",
+    "properties": [
+        {
+            "name": "textures",
+            "signature": "signature value",
+            "value": "base64 encoded value"
+        },
+        {
+            "name": "chrly",
+            "value": "how do you tame a horse in Minecraft?"
+        }
+    ]
+}
+```
+
+If there is no requested `username` or `mojangSignature` field isn't set, `204` status code will be sent.
+
+#### `GET /skins?name={username}`
+
+Equivalent of the `GET /skins/{username}.png`, but constructed especially for old Minecraft versions, where username
+placeholder wasn't used.
+
+#### `GET /cloaks?name={username}`
+
+Equivalent of the `GET /cloaks/{username}.png`, but constructed especially for old Minecraft versions, where username
+placeholder wasn't used.
+
+### Records manipulating API
+
+Each request to the internal API should be performed with the Bearer authorization header. Example curl request:

 ```sh
+curl -X POST -i http://chrly.domain.com/api/skins \
+  -H "Authorization: Bearer Ym9zY236Ym9zY28="
+```
+
+You can obtain token by executing `docker-compose run --rm app token`.
+
+#### `POST /api/skins`
+
+> **Warning**: skin uploading via `skin` field is not implemented for now.
+
+Endpoint allows you to create or update skin record for a username. To upload skin, you have to send multipart
+form data. `form-urlencoded` also supported, but, as you may know, it doesn't support files uploading.
+
+**Request params:**
+
+| Field           | Type   | Description                                                                    |
+|-----------------|--------|--------------------------------------------------------------------------------|
+| identityId      | int    | Unique record identifier.                                                      |
+| username        | string | Username. Case insensitive.                                                    |
+| uuid            | uuid   | UUID of the user.                                                              |
+| skinId          | int    | Skin identifier.                                                               |
+| hash            | string | Skin's hash. Algorithm can be any. For example `md5`.                          |
+| is1_8           | bool   | Does the skin have the new format (64x64).                                     |
+| isSlim          | bool   | Does skin have slim arms (Alex model).                                         |
+| mojangTextures  | string | Mojang textures field. It must be a base64 encoded json string. Not required.  |
+| mojangSignature | string | Signature for Mojang textures, which is required when `mojangTextures` passed. |
+| url             | string | Actual url of the skin. You have to pass this parameter or `skin`.             |
+| skin            | file   | Skin file. You have to pass this parameter or `url`.                           |
+
+If successful you'll receive `201` status code. In the case of failure there will be `400` status code and errors list
+as json:
+
+```json
+{
+    "errors": {
+        "identityId": [
+            "The identityId field must be numeric"
+        ]
+    }
+}
+```
+
+#### `DELETE /api/skins/id:{identityId}`
+
+Performs record removal by identity id. Request body is not required. On success you will receive `204` status code.
+On failure it'll be `404` with the json body:
+
+```json
+{
+    "error": "Cannot find record for requested user id"
+}
+```
+
+#### `DELETE /api/skins/{username}`
+
+Same endpoint as above but it removes record by identity's username. Have the same behavior, but in case of failure
+response will be:
+
+```json
+{
+    "error": "Cannot find record for requested username"
+}
+```
+
+## Development
+
+First of all you should install the [latest stable version of Go](https://golang.org/doc/install) and set `GOPATH`
+environment variable.
+
+This project uses [`dep`](https://github.com/golang/dep) for dependencies management, so it
+[should be installed](https://github.com/golang/dep#installation) too.
+
+Then you must fork this repository. Now follow these steps:
+
+```sh
+# Get the source code
+go get github.com/elyby/chrly
+# Switch to the project folder
+cd $GOPATH/src/github.com/elyby/chrly
+# Install dependencies (it can take a while)
+dep ensure
+# Add your fork link as a remote
+git remote add fork git@github.com:your-username/chrly.git
+# Create a new branch for your task
+git checkout -b iss-123
+```
+
+You only need to execute `go run main.go` to run the project, but without Redis database and a secret key it won't work
+for very long. You have to export `CHRLY_SECRET` environment variable globally or pass it via `env`:
+
+```sh
+env CHRLY_SECRET=some_local_secret go run main.go serve
+```
+
+Redis can be installed manually, but if you have [Docker installed](https://docs.docker.com/install/), you can run
+predefined docker-compose service. Simply execute the next commands:
+
+```sh
+cp docker-compose.dev.yml docker-compose.yml
 docker-compose up -d
 ```

-Если нужно пересобрать весь контейнер, то выполняем следующее:
+If your Redis instance isn't located at the `localhost`, you can change host by editing environment variable
+`STORAGE_REDIS_HOST`.

-```
-docker-compose stop app  # Останавливаем конейтнер, если он ещё работает
-docker-compose rm -f app # Удаляем конейтнер
-docker-compose build app # Запускаем билд по новой
-docker-compose up -d app # Поднимаем свежесобранный контейнер обратно
-```
-
-### Шорткаты для разработки
-
-Потом это надо преобразовать в нормальные доки.
-
-Run Redis:
-
-```sh
-docker run --rm \
-p 6379:6379 \
-redis:3.0-alpine
-```
-
-Run RabbitMQ:
-
-```sh
-docker run --rm \
-p 5672:5672 \
-e RABBITMQ_DEFAULT_USER=ely-skinsystem-app \
-e RABBITMQ_DEFAULT_PASS=ely-skinsystem-app-password \
-e RABBITMQ_DEFAULT_VHOST=/ely \
-rabbitmq:3.6
-```
+After all of that `go run main.go serve` should successfully start the application.
+To run tests execute `go test ./...`. If your Go version is older than 1.9, then run a `/script/test`.
