Government
Project 2025 proposes that the entire federal bureaucracy, including independent agencies such as the Department of Justice, be placed under direct presidential control - a controversial idea known as "unitary executive theory".
In practice, that would streamline decision-making, allowing the president to directly implement policies in a number of areas.
The proposals also call for eliminating job protections for thousands of government employees, who could then be replaced by political appointees.
The document labels the FBI a "bloated, arrogant, increasingly lawless organization". It calls for drastic overhauls of this and several other federal agencies, as well as the complete elimination of the Department of Education.
The Republican Party platform includes a proposal to "declassify government records, root out wrongdoers, and fire corrupt employees", pledges to slash regulation and government spending, and also suggests eliminating the Department of Education. But it stops short of proposing a sweeping overhaul of federal agencies as outlined in Project 2025.
Immigration
EPA Increased funding for a wall on the US-Mexico border - one of Trump's signature proposals in 2016 - is proposed in the document.
Project 2025 also proposes dismantling the Department of Homeland Security and combining it with other immigration enforcement units in other agencies, creating a much larger and more powerful border policing operation.
Other proposals include eliminating visa categories for crime and human trafficking victims, increasing fees on immigrants and allowing fast-tracked applications for migrants who pay a premium.
Not all of those details are repeated in the Republican platform document, but the overall headlines are similar - the party is promising to implement the "largest deportation programme in American history".
Climate and economy
The document proposes slashing federal money for research and investment in renewable energy, and calls for the next president to "stop the war on oil and natural gas".
Carbon-reduction goals would be replaced by efforts to increase energy production and energy security.
The paper sets out two competing visions on tariffs, and is divided on whether the next president should try to boost free trade or raise barriers to imports.
But the economic advisers suggest that a second Trump administration should slash corporate and income taxes, abolish the Federal Reserve and even consider a return to gold-backed currency.
On this and many other topics, Project 2025 is more detailed and goes further than the official Republican platform, which talks of bringing down inflation and drilling for oil to reduce energy costs, but is thin on specific policy proposals.
Abortion and family
Project 2025 does not call outright for a nationwide abortion ban.
However, it proposes withdrawing the abortion pill mifepristone from the market, and using existing but little-enforced laws to stop the drug being sent through the post.
The document suggests that the department of Health and Human Services should "maintain a biblically based, social science-reinforced definition of marriage and family".
On this issue at least, the document differs fairly substantially from the Republican platform, which only mentions the word "abortion" once. The platform says abortion laws should be left to individual states and that late-term abortions (which it does not define) should be banned.
It adds that that access to prenatal care, birth control and in-vitro fertilisation should be protected. The party platform makes no mention of cracking down on the distribution of mifepristone.
Tech and education
Under the proposals, pornography would be banned, and tech and telecoms companies that allow access would be shut down.
The document calls for school choice and parental control over schools, and takes aim at what it calls "woke propaganda".
It proposes to eliminate a long list of terms from all laws and federal regulations, including "sexual orientation", "gender equality", "abortion" and "reproductive rights".
Project 2025 aims to end diversity, equity and inclusion programs in schools and government departments as part of what it describes as a wider crackdown on "woke" ideology.
Its proposals are broadly reflected in the Republican platform, which in addition to calling for the abolishing the Department of Education, aims to boost school choice and parental control over education and criticises what the party calls the "inappropriate political indoctrination of our children".
The plan's future
Project 2025 is backed by a $22m (£17m) budget and includes strategies for implementing policies immediately after the presidential inauguration in January 2025.
Heritage is also creating a database of conservative loyalists to fill government positions, and a programme to train those new workers.
Democrats led by Jared Huffman, a congressman from California, have launched a Stop Project 2025 Task Force.
And many of the proposals would likely face immediate legal challenges from Trump's opponents if implemented. Soros will cark it when he reads this
