+# Content directory tooling
+
+## Definitions
+
+In order to make this documentation as clear as possible it is important to make a strict distinction between two types of schemas:
+
+- `json-schemas` mean files with `.schema.json` extension. This is a common standard for describing how to validate other `json` files or objects (ie. a `package.json` file may be an example of a file that can be supported by a `json-schema`). A documentation of this standard can be found here: https://json-schema.org/
+- `runtime-scheams` means schemas as they are "understood" by the `content-directory` runtime module, so schemas that can be added to classes via `api.tx.contentDirectory.addClassSchema` and linked to entities via `api.tx.contentDirectory.addSchemaSupportToEntity`
+
+## Content directory input
+
+### Initializing content directory
+
+In order to intialize the content directory on a development chain based on data that is provided in form of json files inside `/inputs` directory (`classes`, `schemas` and example entities - `entityBatches`), we can run:
+
+```
+yarn workspace cd-schemas initialize:dev
+```
+
+This will handle:
+
+- Creating a membership for `ALICE` (if not already created)
+- Setting (hiring) `ALICE` as content curators lead (if not already set)
+- Creating classes in the runtime based on `inputs/classes` json inputs (if the content directory is currently empty)
+- Creating schemas in the runtime based on `inputs/schemas` and adding them to the related classes
+- Creating entities based on `inputs/entityBatches`. Those json inputs allow describing entities and relationships between them in a simplified way and are then converted into one huge `api.tx.contentDirectory.transaction` call (this is further described in _**Entity batches**_ section).
+
+### Input files naming
+
+In order to get the full benefit of the tooling, in some cases you may need to respect a specific pattern of file naming:
+
+Each input file name should end with `Class`, `Schema` or `Batch` (depending on the input type, ie. `LanguageBatch`).
+It is also recommended that each of those file names starts with a class name (currently in `entityBatches` there's no distinction between schemas and classes, as it is assumed there will be a one-to-one relationship between them)
+
+### `json-schemas` support for json inputs in `VSCode`
+
+In order to link json files inside `inputs` directory to `json-schemas` inside `schemas` and have them validated in real-time by the IDE, follow the steps below:
+
+**If you don't have `.vscode/settings.json` in the root monorepo workspace yet:**
+
+1. Create `.vscode` directory inside your monorepo workspace
+1. Copy `vscode-recommended.settings.json` into this `.vscode` directory and rename it to `settings.json`.
+
+**If you already have the `.vscode/settings.json` file in the root monorepo workspace:**
+
+1. Copy the settings from `vscode-recommended.settings.json` and merge them with the existing `.vscode/settings.json`
+
+Now all the json files matching `*Class.json`, `*Schema.json`, `*{EntityName}Batch.json` patters will be linked to the correct `json schemas`. If you edit any file inside `inputs` or add a new one that follows the naming pattern (described in _Input files naming_), you should get the benefit of autocompleted properties, validated input, on-hover tooltips with property descriptions etc.
+
+For more context, see: https://code.visualstudio.com/docs/languages/json
+
+### Validate inputs and `json-schemas` via a command
+
+All inputs inside `inputs` directory and `json-schemas` used to validate those inputs can also be validated using `yarn workspace cd-schemas validate` command. This is mainly to facilitate checking the validity of `.json` and `.schema.json` files inside `content-directory-schemas` through CI.
+
+### Entity batches
+
+The concept of entity batches (`inputs/entityBatches`) basically provides an easy way of describing complex input to content directory (ie. many entities related to each other in many ways) without the need to deal with lower-level, hard-to-validate runtime operations like `CreateEntity` and `AddSchemaSupportEntity` and trying to glue them together into a huge `api.tx.contentDirectory.transaction` call.
+
+Instead, the script that initializes the content directory (`scripts/initializeContentDir.ts`) is able to generate the complex `api.tx.contentDirectory.transaction` call based on a more human-readable input provided in `inputs/entityBatches`.
+
+This input can be provided as a simple json array of objects matching `{ [propertyName]: propertyValue}` structure.
+
+For example, in order to describe creating entities as simple as `Language`, which only has `Code` and `Name` properties, we can just create an array of objects like:
+
+```
+[
+  { "Code": "EN", "Name": "English" },
+  { "Code": "RU", "Name": "Russian" },
+  { "Code": "DE", "Name": "German" }
+]
+```
+
+_(This is the actual content of `inputs/entityBatches/LanguageBatch.json`)_
+
+#### Related entities
+
+There also exists a specific syntax for defining relations between entities in batches.
+We can do it by either using `"new"` or `"existing"` keyword.
+
+- The `"new"` keyword allows describing a scenario where related entity should be created **along with** the main entity and then referenced by it. An example of this could be `Video` and `VideoMedia` which have a one-to-one relationship and it doesn't make much sense to specify them in separate batches. Instead, we can use a syntax like:
+
+```
+{
+  "title": "Awesome video",
+  /* other Video properties... */
+  "media": { "new": {
+    "pixelWidth": 1024,
+    "pixelHeight": 764,
+    /* other VideoMedia object properties... */
+  }
+}
+```
+
+- The `"existing"` keyword allows referencing an entity created as part of any other batch inside `inputs/entityBatches`. We can do it by specifying the value of **any unique property of the referenced entity**. So, for example to reference a `Language` entity from `VideoBatch.json` file, we use this syntax:
+
+```
+{
+  "title": "Awesome video",
+  /* other Video properties... */
+  "language": { "existing": { "Code": "EN" } }
+}
+```
+
+## `json-schemas` and tooling
+
+### Entity `json-schemas`
+
+There is a script that provides an easy way of converting `runtime-schemas` (based on inputs from `inputs/schemas`) to `json-schemas` (`.schema.json` files) which allow validating the input (ie. json files) describing some specific entities. It can be run with:
+
+```
+yarn workspace cd-schemas generate:entity-schemas
+```
+
+Those `json-schemas` are currently mainly used for validating the inputs inside `inputs/entityBatches`.
+
+The generated `json-schemas` include:
+
+- `schemas/entities` - `json-schemas` that provide validation for given entity (ie. `Video`) input. They can, for example, check if the `title` property in a json object is a string that is no longer than `64` characters. They are used to validate a single entity in `inputs/entityBatches`, but can also be re-used to provide "frontend" validation of any entity input to the content directory (ie. input provided to/via `joystream-cli`).
+- `schemas/entityReferences` - `json-schemas` that describe how an entity of given class can be referenced. Currently they are used for providing an easy way of referencing entites between batches in `inputs/entityBatches`. For more details on how entities can be referenced in batches, read the _**Entity batches**_ section.
+- `schemas/entityBatches` - very simple `json-schemas` that basically just provide `array` wrappers over `schemas/entities`. Those are the actual `json-schemas` that can be linked to json input files inside `inputs/entityBatches` (ie. via `.vscode/settings.json`)
+
+### Typescript support
+
+Thanks to the `json-schema-to-typescript` library, we can very simply generate Typescript interfaces based on existing `json-schemas`. This can be done via:
+
+```
+yarn workspace cd-schemas generate:types
+```
+
+This command will generate:
+
+- `types/entities` based on `schemas/entities`, providing typescript interfaces for entities like `Video` etc. (note that this interface will include a peculiar way of describing entity relationships, further described in _**Entity batches**_ section)
+- `types/extrinsics` based on `schemas/extrinsics`, providing typescript interfaces for input to extrinsics like `AddClassSchema` and `CreateClass`
+
+The most obvious use-case of those interfaces currently is that when we're parsing any json files inside `inputs` using a Typescript code, we can assert that the resulting object will be of given type, ie.:
+
+```
+const createClassInput = JSON.parse(fs.readFileSync('/path/to/inputs/LanguageClass.json')) as CreateClass
+```
+
+Besides that, a Typescript code can be written to generate some inputs (ie. using a loop) that can then can be used to create classes/schemas or insert entities into the content directory.
+
+There are a lot of other potential use-cases, but for the purpose of this documentation it should be enough to mention there exists this very easy way of converting `.schema.json` files into Typescript interfaces.
+
+## Using as library
+
+The `content-directory-schemas` directory of the monorepo is constructed in such a way, that it should be possible to use it as library and import from it json schemas, types (mentioned in `Typescript support` section) and tools to, for example, convert entity input like this described in the `Entity batches` section into `CreateEntity`, `AddSchemaSupportToEntity` and/or `UpdateEntityPropertyValues` operations.
+
+### Examples
+
+The best way to ilustrate this would be by providing some examples:
+
+#### Creating a channel
+```
+  import { InputParser } from 'cd-schemas'
+  import { ChannelEntity } from 'cd-schemas/types/entities/ChannelEntity'
+  // Other imports...
+
+  async main() {
+    // Initialize the api, SENDER_KEYPAIR and SENDER_MEMBER_ID...
+
+    const channel: ChannelEntity = {
+      title: 'Example channel',
+      description: 'This is an example channel',
+      language: { existing: { code: 'EN' } },
+      coverPhotoUrl: '',
+      avatarPhotoURL: '',
+      isPublic: true,
+    }
+
+    const parser = InputParser.createWithKnownSchemas(api, [
+      {
+        className: 'Channel',
+        entries: [channel],
+      },
+    ])
+
+    const operations = await parser.getEntityBatchOperations()
+    await api.tx.contentDirectory
+      .transaction({ Member: SENDER_MEMBER_ID }, operations)
+      .signAndSend(SENDER_KEYPAIR)
+  }
+```
+_Full example with comments can be found in `content-directory-schemas/examples/createChannel.ts` and ran with `yarn workspace cd-schemas example:createChannel`_
+
+#### Creating a video
+```
+import { InputParser } from 'cd-schemas'
+import { VideoEntity } from 'cd-schemas/types/entities/VideoEntity'
+// ...
+
+async main() {
+  // ...
+
+  const video: VideoEntity = {
+    title: 'Example video',
+    description: 'This is an example video',
+    language: { existing: { code: 'EN' } },
+    category: { existing: { name: 'Education' } },
+    channel: { existing: { title: 'Example channel' } },
+    media: {
+      new: {
+        encoding: { existing: { name: 'H.263_MP4' } },
+        pixelHeight: 600,
+        pixelWidth: 800,
+        location: {
+          new: {
+            httpMediaLocation: {
+              new: { url: 'https://testnet.joystream.org/' },
+            },
+          },
+        },
+      },
+    },
+    license: {
+      new: {
+        knownLicense: {
+          existing: { code: 'CC_BY' },
+        },
+      },
+    },
+    duration: 3600,
+    thumbnailURL: '',
+    isExplicit: false,
+    isPublic: true,
+  }
+
+  const parser = InputParser.createWithKnownSchemas(api, [
+    {
+      className: 'Video',
+      entries: [video],
+    },
+  ])
+
+  const operations = await parser.getEntityBatchOperations()
+  await api.tx.contentDirectory
+    .transaction({ Member: SENDER_MEMBER_ID }, operations)
+    .signAndSend(SENDER_KEYPAIR)
+}
+```
+_Full example with comments can be found in `content-directory-schemas/examples/createVideo.ts` and ran with `yarn workspace cd-schemas example:createChannel`_
+
+#### Update channel title
+
+```
+import { InputParser } from 'cd-schemas'
+import { ChannelEntity } from 'cd-schemas/types/entities/ChannelEntity'
+// ...
+
+async function main() {
+  // ...
+
+  const channelUpdateInput: Partial<ChannelEntity> = {
+    title: 'Updated channel title',
+  }
+
+  const parser = InputParser.createWithKnownSchemas(api)
+
+  const CHANNEL_ID = await parser.findEntityIdByUniqueQuery({ title: 'Example channel' }, 'Channel')
+
+  const updateOperations = await parser.getEntityUpdateOperations(channelUpdateInput, 'Channel', CHANNEL_ID)
+
+  await api.tx.contentDirectory
+    .transaction({ Member: SENDER_MEMBER_ID }, [updateOperation])
+    .signAndSend(SENDER_KEYPAIR)
+}
+```
+_Full example with comments can be found in `content-directory-schemas/examples/updateChannelTitle.ts` and ran with `yarn workspace cd-schemas example:updateChannelTitle`_
+
+Note: Updates can also inlucde `new` and `existing` keywords. In case `new` is specified inside the update - `CreateEntity` and `AddSchemaSupportToEntity` operations will be included as part of the operations returned by `InputParser.getEntityUpdateOperations`.
+
+## Current limitations
+
+Some limitations that should be dealt with in the nearest future:
+
+- Filename restrictions described in **_Input files naming_** section
+- Some code runs on the assumption that there is only one schema for each class, which is very limiting
+- `Vector<Reference>` property type is not yet supported when parsing entity batches
